1 00:00:04,240 --> 00:00:07,440 Speaker 1: Get in text with technology with tex Stuff from Hastaf. 2 00:00:11,680 --> 00:00:14,920 Speaker 1: Hey there, and welcome to tech Stuff. I'm Jonathan Strickland. 3 00:00:15,200 --> 00:00:19,680 Speaker 1: I'm still on vacation, vacating which means that we're going 4 00:00:19,720 --> 00:00:24,439 Speaker 1: to enjoy another classic episode of tech Stuff, but we're 5 00:00:24,480 --> 00:00:27,240 Speaker 1: doing so for a specific reason because of a little 6 00:00:28,040 --> 00:00:31,840 Speaker 1: listener mail. And this comes from Troy, who says, good afternoon. 7 00:00:31,920 --> 00:00:34,159 Speaker 1: I've recently started to listen to your podcast as my 8 00:00:34,280 --> 00:00:37,640 Speaker 1: tech interests begin to grow. I was hoping you could 9 00:00:37,640 --> 00:00:40,479 Speaker 1: do an episode on WiFi versus Y Max would be 10 00:00:40,520 --> 00:00:44,120 Speaker 1: great to learn about that. Well, Troy, way back in 11 00:00:44,159 --> 00:00:48,080 Speaker 1: the day, I'm talking November of two thousand nine, Chris Pallette, 12 00:00:48,120 --> 00:00:51,960 Speaker 1: my original co host, and I talked about WiFi and 13 00:00:52,000 --> 00:00:54,680 Speaker 1: the different types of WiFi, and we also talked about 14 00:00:54,680 --> 00:00:57,880 Speaker 1: Wi Max, which is not a type of WiFi. We 15 00:00:58,040 --> 00:01:01,120 Speaker 1: grouped it under there because it was the easiest way 16 00:01:01,160 --> 00:01:04,400 Speaker 1: to explain it to people who are unfamiliar with it. 17 00:01:04,760 --> 00:01:09,360 Speaker 1: But I regret actually calling the episode the different types 18 00:01:09,400 --> 00:01:12,440 Speaker 1: of WiFi, because why that's that's that's misleading. Why Max 19 00:01:12,480 --> 00:01:14,920 Speaker 1: and WiFi are two different things. There are actually two 20 00:01:14,959 --> 00:01:20,399 Speaker 1: different communications standards designed to transmit data wirelessly, So you 21 00:01:20,440 --> 00:01:23,320 Speaker 1: can think of it as two different approaches to accomplish 22 00:01:23,600 --> 00:01:28,880 Speaker 1: similar goals. Now, why MAX can transmit up to about 23 00:01:28,880 --> 00:01:32,360 Speaker 1: a gigabit per second for fixed stations, in other words, 24 00:01:32,400 --> 00:01:34,840 Speaker 1: a station that is in a fixed location, it's not 25 00:01:34,920 --> 00:01:38,920 Speaker 1: moving around, and it can also transmit this at a 26 00:01:39,040 --> 00:01:43,120 Speaker 1: much wider area than say WiFi could. Uh. That is 27 00:01:43,880 --> 00:01:49,120 Speaker 1: why why Max is really being used in municipal wireless data. 28 00:01:49,560 --> 00:01:52,600 Speaker 1: So in other words, it's it's kind of a a 29 00:01:52,640 --> 00:01:57,560 Speaker 1: replacement for wired connections. You wouldn't use cables instead, you 30 00:01:57,560 --> 00:02:00,480 Speaker 1: would have these towers that would transmit why MAX signals 31 00:02:00,960 --> 00:02:05,320 Speaker 1: using this specific standard, and you could then provide internet 32 00:02:05,320 --> 00:02:09,760 Speaker 1: connectivity to different to a large area, whereas WiFi tends 33 00:02:09,800 --> 00:02:13,000 Speaker 1: to be much more localized, it doesn't have as broad 34 00:02:13,040 --> 00:02:16,480 Speaker 1: a transmission range, but it can also go really fast. 35 00:02:16,880 --> 00:02:20,160 Speaker 1: In fact, the the eight O two dot eleven a 36 00:02:20,400 --> 00:02:24,640 Speaker 1: C standard is on the five giga Hurts band of frequencies, 37 00:02:24,680 --> 00:02:27,920 Speaker 1: because WiFi uses two different frequency bands depending upon the 38 00:02:27,919 --> 00:02:32,040 Speaker 1: standard you're using, and can also reach a gigabit per 39 00:02:32,080 --> 00:02:36,560 Speaker 1: second or even theoretically faster than that. So the two 40 00:02:36,560 --> 00:02:39,480 Speaker 1: are able to transmit data at similar speeds, but doing 41 00:02:39,520 --> 00:02:43,000 Speaker 1: so in a different way, and I will now transfer 42 00:02:43,120 --> 00:02:47,359 Speaker 1: this over to the episode where Chris and I talked 43 00:02:47,480 --> 00:02:50,720 Speaker 1: more about these different types. Keeping in mind this goes 44 00:02:50,760 --> 00:02:54,040 Speaker 1: back to two thousand nine and the standards have evolved 45 00:02:54,400 --> 00:03:02,280 Speaker 1: considerably since then, So enjoy this episode. We thought we'd 46 00:03:02,280 --> 00:03:05,760 Speaker 1: talked a little bit about the different kinds of wireless 47 00:03:06,440 --> 00:03:09,120 Speaker 1: networks out there are the ones that use the various 48 00:03:09,280 --> 00:03:13,200 Speaker 1: standards set out by our good friends at the Triple E, 49 00:03:13,600 --> 00:03:20,160 Speaker 1: or as I always like to call them, a yeah right, Yeah, 50 00:03:20,320 --> 00:03:24,880 Speaker 1: you know, early early networks were sort of like tin 51 00:03:24,960 --> 00:03:27,720 Speaker 1: cans with the string between them. This sort of makes 52 00:03:27,760 --> 00:03:30,959 Speaker 1: this string virtual. Yeah, there you go. That's all you 53 00:03:31,000 --> 00:03:38,360 Speaker 1: need to know. There's the whole we're gonna alright, So anyway, uh, 54 00:03:38,640 --> 00:03:41,480 Speaker 1: we're talking about a set of standards that in general 55 00:03:41,760 --> 00:03:45,920 Speaker 1: fall under the designation eight zero two point one one. 56 00:03:46,320 --> 00:03:49,480 Speaker 1: Doesn't that easy? Yeah, well it's it's the most those 57 00:03:49,520 --> 00:03:55,520 Speaker 1: are the most common frequency variations of wireless networking. So 58 00:03:56,960 --> 00:04:00,400 Speaker 1: the way you h you'll see on things like outers 59 00:04:00,400 --> 00:04:03,000 Speaker 1: and modems and stuff. You'll see this number followed by 60 00:04:03,040 --> 00:04:06,400 Speaker 1: a letter, and that tells you which of the specific 61 00:04:06,440 --> 00:04:08,800 Speaker 1: sets of standards you're working with. Now you've got to 62 00:04:08,920 --> 00:04:12,560 Speaker 1: understand what I was getting ready to correct myself because 63 00:04:12,600 --> 00:04:16,400 Speaker 1: I said, and that's not a frequency, no, No, it's 64 00:04:16,480 --> 00:04:19,400 Speaker 1: just a designation. Is a designation? Yes, so so the 65 00:04:19,520 --> 00:04:24,599 Speaker 1: I triple ey. They work on various designations for different 66 00:04:25,120 --> 00:04:28,279 Speaker 1: UM networking solutions, and with the eight to two point 67 00:04:28,360 --> 00:04:31,000 Speaker 1: one one, you have different working groups all working on 68 00:04:31,080 --> 00:04:35,679 Speaker 1: different sets of standards to try and create the most 69 00:04:35,800 --> 00:04:41,080 Speaker 1: stable and reliable form of wireless networking in this case 70 00:04:41,080 --> 00:04:44,880 Speaker 1: wireless networking UM. And it's it's a little confusing because 71 00:04:44,960 --> 00:04:47,280 Speaker 1: you have all these different groups working on working from 72 00:04:47,279 --> 00:04:50,760 Speaker 1: the same basic set of standards, but they're all tweaking 73 00:04:50,800 --> 00:04:53,559 Speaker 1: them in different ways to try and get different kinds 74 00:04:53,560 --> 00:04:57,320 Speaker 1: of performance out of them. So let's try and go 75 00:04:57,440 --> 00:04:59,880 Speaker 1: through some of these. It's really kind of complex, but 76 00:05:00,120 --> 00:05:03,600 Speaker 1: um yeah. One of the things to uh that's kind 77 00:05:03,600 --> 00:05:07,839 Speaker 1: of interesting about these different standards is, UH, as we 78 00:05:07,880 --> 00:05:10,280 Speaker 1: start going through them, if we are going through them 79 00:05:10,279 --> 00:05:13,520 Speaker 1: in alphabetical order, you will find that they do not 80 00:05:13,760 --> 00:05:18,200 Speaker 1: necessarily uh go start from the bottom up, like if 81 00:05:18,240 --> 00:05:22,719 Speaker 1: we start with eight eight O two dot eleven A. UH. 82 00:05:22,760 --> 00:05:26,760 Speaker 1: This actually operates on the five gigga hurts frequency and 83 00:05:27,040 --> 00:05:31,919 Speaker 1: can carry up to fifty four megabets of data per second. Uh, 84 00:05:32,040 --> 00:05:34,760 Speaker 1: in contrast at two dot eleven B you'd figure to 85 00:05:34,800 --> 00:05:38,320 Speaker 1: be faster. No, actually it's not. It operates at the 86 00:05:38,360 --> 00:05:41,760 Speaker 1: two point four gigga hurts frequency and only can handle 87 00:05:41,800 --> 00:05:45,360 Speaker 1: eleven megabits of data per second. And that's just one 88 00:05:45,400 --> 00:05:47,920 Speaker 1: of those things that makes it so confusing is you 89 00:05:47,920 --> 00:05:50,039 Speaker 1: you'd figure there would be a logical progression there, and 90 00:05:50,080 --> 00:05:53,680 Speaker 1: there's not necessarily one. Yeah, so what do you think 91 00:05:53,680 --> 00:05:55,920 Speaker 1: should we go by just by letter even though it's 92 00:05:55,920 --> 00:05:58,599 Speaker 1: not logical progression necessarily, but just to make it easier 93 00:05:58,640 --> 00:06:01,520 Speaker 1: to move from one to the other. Those two, those 94 00:06:01,520 --> 00:06:04,040 Speaker 1: two do fit well together because they were the first 95 00:06:04,200 --> 00:06:10,280 Speaker 1: two very common standards, at least in my experience. Well. 96 00:06:10,320 --> 00:06:16,080 Speaker 1: ATO two point eleven B uses UH unregulated radio signal 97 00:06:16,080 --> 00:06:21,520 Speaker 1: frequencies in the two point four gigga hurts range. So uh, 98 00:06:21,800 --> 00:06:24,120 Speaker 1: here's something. Here's some things about the ATO two point 99 00:06:24,160 --> 00:06:29,520 Speaker 1: one one B set standards. It's single ranges is pretty good, 100 00:06:30,240 --> 00:06:32,479 Speaker 1: um in the two point four gigga Hurts range, and 101 00:06:32,680 --> 00:06:36,280 Speaker 1: it's not going to have problems with obstructions that some 102 00:06:36,320 --> 00:06:39,760 Speaker 1: other frequencies do. So, in other words, you might be 103 00:06:39,839 --> 00:06:43,840 Speaker 1: able to use this kind of signal through walls things 104 00:06:43,880 --> 00:06:46,320 Speaker 1: like that, you don't have to worry about losing signal 105 00:06:46,360 --> 00:06:49,560 Speaker 1: as soon as you turn a corner some UH from 106 00:06:49,600 --> 00:06:54,040 Speaker 1: the source of the the frequency UM, and it's not 107 00:06:54,400 --> 00:06:58,560 Speaker 1: very expensive. The range is pretty good, UM, but it's 108 00:06:59,120 --> 00:07:01,920 Speaker 1: not a very it's not very fast, as you pointed out, 109 00:07:02,360 --> 00:07:04,760 Speaker 1: you know, compared to eight to two point eleven A. 110 00:07:05,440 --> 00:07:11,800 Speaker 1: It's it's fairly slow. UM. And because it's an unregulated frequency, 111 00:07:12,160 --> 00:07:16,320 Speaker 1: some other appliances that generate radio frequencies can cause interference 112 00:07:16,480 --> 00:07:20,920 Speaker 1: within that wireless UH frequency because you have to remember 113 00:07:21,880 --> 00:07:24,800 Speaker 1: the computer you're using whatever, Like if you have a 114 00:07:24,840 --> 00:07:30,040 Speaker 1: wireless router that's broadcasting WiFi on this set of standards, 115 00:07:30,400 --> 00:07:33,560 Speaker 1: if it's using unregulated radio frequencies, that means that it 116 00:07:33,600 --> 00:07:36,960 Speaker 1: can fall within a wider range, and that things that 117 00:07:37,360 --> 00:07:40,520 Speaker 1: also generate radio frequencies within that range. When you're using 118 00:07:40,560 --> 00:07:42,679 Speaker 1: your computer, your computer doesn't know which one of those 119 00:07:42,760 --> 00:07:45,040 Speaker 1: which of those signals are coming from your router and 120 00:07:45,080 --> 00:07:47,960 Speaker 1: which are coming from other devices. So that's where you 121 00:07:47,960 --> 00:07:52,000 Speaker 1: get your your interference. If you're saying, what kind of 122 00:07:52,040 --> 00:07:55,200 Speaker 1: interference could you possibly be talking about? While we're talking 123 00:07:55,240 --> 00:07:58,880 Speaker 1: about things like your cordless phone in your house, for example, 124 00:07:59,080 --> 00:08:04,400 Speaker 1: or perhaps an alarm system where you have uh wireless 125 00:08:04,760 --> 00:08:08,920 Speaker 1: UM the devices that go above your windows and doors, 126 00:08:09,200 --> 00:08:12,320 Speaker 1: if you know, it uses radio frequencies to talk to 127 00:08:12,360 --> 00:08:17,200 Speaker 1: the main box UM and baby monitors stuff like that. 128 00:08:17,640 --> 00:08:20,920 Speaker 1: Those are all using you know, those radio frequencies in 129 00:08:21,040 --> 00:08:24,080 Speaker 1: those ranges. And of course you can you can buy 130 00:08:24,160 --> 00:08:28,240 Speaker 1: cordless phones and and not to over use that word 131 00:08:28,560 --> 00:08:32,280 Speaker 1: range of different frequencies. UM. So you could try to 132 00:08:32,280 --> 00:08:34,679 Speaker 1: get to to get around that. But that's one of 133 00:08:34,720 --> 00:08:38,040 Speaker 1: those things that I think they've been trying to improve 134 00:08:38,200 --> 00:08:40,160 Speaker 1: is is cut down on some of the interference. And 135 00:08:40,200 --> 00:08:45,160 Speaker 1: that's why um ATO two eleven A uses the orthogonal 136 00:08:45,200 --> 00:08:50,240 Speaker 1: frequency division multiplexing. Basically, it's it's just a system of 137 00:08:50,280 --> 00:08:53,920 Speaker 1: splitting down that signal into a group of sub signals 138 00:08:54,360 --> 00:08:57,480 Speaker 1: to kind of make it less likely that you're going 139 00:08:57,520 --> 00:09:00,360 Speaker 1: to be interfered with. It breaks it down so that 140 00:09:00,440 --> 00:09:03,280 Speaker 1: it's not all in one one signal, Right, so you're 141 00:09:03,320 --> 00:09:06,240 Speaker 1: not gonna you're not gonna have the same interference issues. 142 00:09:06,800 --> 00:09:10,000 Speaker 1: UM it's you shouldn't. And again, like we point out, 143 00:09:10,000 --> 00:09:12,880 Speaker 1: it is faster. ATO two point eleven A is faster 144 00:09:12,920 --> 00:09:15,440 Speaker 1: than NATO to a point eleven B. But it's also 145 00:09:15,880 --> 00:09:19,400 Speaker 1: it's UM range is shorter, it's not it doesn't go 146 00:09:19,480 --> 00:09:22,679 Speaker 1: as far, and because of the frequencies that uses UM, 147 00:09:22,720 --> 00:09:26,400 Speaker 1: it's a little more easily obstructed, So you can't necessarily 148 00:09:26,440 --> 00:09:29,520 Speaker 1: broadcast through several walls. If you have a large house 149 00:09:29,520 --> 00:09:32,920 Speaker 1: and you've got a wireless router in the middle, then 150 00:09:33,080 --> 00:09:35,920 Speaker 1: you may notice that as you move away you start 151 00:09:35,960 --> 00:09:38,719 Speaker 1: having problems getting a signal. I also suggested you don't 152 00:09:38,760 --> 00:09:43,080 Speaker 1: make your walls out of lead. Yeah, I um, never again, 153 00:09:43,760 --> 00:09:46,400 Speaker 1: never again. I tell you one thing. You know what, 154 00:09:46,760 --> 00:09:48,800 Speaker 1: You make your walls out of lead, and you invite 155 00:09:48,840 --> 00:09:52,040 Speaker 1: Superman over. The dude is just a total jerk face 156 00:09:52,600 --> 00:09:57,079 Speaker 1: the entire time. He's just easy, right, He's just standing around, 157 00:09:57,120 --> 00:10:00,280 Speaker 1: staring at the walls and just mumbling hers. I can't 158 00:10:00,280 --> 00:10:04,280 Speaker 1: even repeat the things that man says. He just a 159 00:10:04,280 --> 00:10:07,120 Speaker 1: lot of mouth on that guy. At any rate. I 160 00:10:07,679 --> 00:10:10,680 Speaker 1: had no idea that my little joke would turn so awry. No, 161 00:10:10,840 --> 00:10:13,199 Speaker 1: but tell you what, green Lantern is awesome. You get 162 00:10:13,200 --> 00:10:16,199 Speaker 1: a few drinks in him, so uh so, yeah, eight 163 00:10:16,320 --> 00:10:19,880 Speaker 1: two point eleven. A faster, shorter range also was more expensive. 164 00:10:20,400 --> 00:10:22,240 Speaker 1: Both A and B were being worked on at the 165 00:10:22,240 --> 00:10:26,000 Speaker 1: same time, UM B was. Even though B was slower, 166 00:10:26,320 --> 00:10:28,720 Speaker 1: it was less expensive and had a greater range, so 167 00:10:28,800 --> 00:10:31,120 Speaker 1: it it caught on a lot faster than A did. 168 00:10:31,679 --> 00:10:34,120 Speaker 1: UM A was much more expensive, so you didn't really 169 00:10:34,160 --> 00:10:37,360 Speaker 1: see that getting adopted in home networks as much. But 170 00:10:37,400 --> 00:10:41,319 Speaker 1: that brings us up to eight to two point eleven G. Yes, 171 00:10:41,559 --> 00:10:45,720 Speaker 1: we skipped a few letters and specifications, yes, UM not that. Yeah, 172 00:10:45,760 --> 00:10:47,520 Speaker 1: I mean you could. If you look up all these 173 00:10:47,559 --> 00:10:51,960 Speaker 1: different numbers UH along with I E, you'll see that 174 00:10:51,960 --> 00:10:54,400 Speaker 1: there are all these different working groups that are working 175 00:10:54,440 --> 00:10:58,800 Speaker 1: on various projects that have different designations. But it gets 176 00:10:58,800 --> 00:11:01,160 Speaker 1: way too complex to talk about all that, especially since 177 00:11:01,160 --> 00:11:03,320 Speaker 1: it doesn't really relate to what we're talking about here 178 00:11:03,360 --> 00:11:07,600 Speaker 1: with home networking. So ATO two yeah, that was A 179 00:11:07,679 --> 00:11:10,719 Speaker 1: and B were popular together for a while, and then 180 00:11:10,840 --> 00:11:14,880 Speaker 1: G was a good sized leap forward. I would say, yeah, 181 00:11:15,000 --> 00:11:18,000 Speaker 1: I agree, and it has been a standard. UM it's 182 00:11:18,000 --> 00:11:21,360 Speaker 1: been widely adopted up until just recently, but we'll get 183 00:11:21,360 --> 00:11:23,640 Speaker 1: into that in a moment. Um ATO two dot eleven 184 00:11:23,640 --> 00:11:27,559 Speaker 1: G also uses the two point for giga hurts spectrum, 185 00:11:27,640 --> 00:11:30,920 Speaker 1: just like ATO two dot eleven B. However, it is 186 00:11:31,000 --> 00:11:34,760 Speaker 1: much faster band with up to fifty four megabits per 187 00:11:34,800 --> 00:11:37,640 Speaker 1: second as I as I see before me, that's the 188 00:11:37,679 --> 00:11:39,520 Speaker 1: figure I have. Yeah, that's the number I have as well. 189 00:11:39,640 --> 00:11:43,280 Speaker 1: So yeah, that's really fast speed. And it's actually the 190 00:11:44,600 --> 00:11:48,199 Speaker 1: it has really much better range. It's not easily obstructed, 191 00:11:48,240 --> 00:11:49,800 Speaker 1: so it's it's kind of taking the best of both 192 00:11:49,800 --> 00:11:53,160 Speaker 1: worlds here. It's got the range and and uh and 193 00:11:53,440 --> 00:11:56,560 Speaker 1: the penetration of ATO two point eleven B and the 194 00:11:56,679 --> 00:12:01,400 Speaker 1: speed and um and and uh well, probably just the 195 00:12:01,440 --> 00:12:06,000 Speaker 1: speed of two point eleven eight UM. But it it 196 00:12:06,080 --> 00:12:08,200 Speaker 1: was a little it's a little more expensive, or at 197 00:12:08,280 --> 00:12:10,480 Speaker 1: least it was more expensive than NATO two point eleven B. 198 00:12:10,800 --> 00:12:13,640 Speaker 1: It took a while for that too kind of become 199 00:12:13,679 --> 00:12:15,599 Speaker 1: the standard and home networks, but that did become the 200 00:12:15,640 --> 00:12:20,679 Speaker 1: standard after shortly after it was introduced, and uh so 201 00:12:20,760 --> 00:12:22,480 Speaker 1: you would look on routers and you would see if 202 00:12:22,600 --> 00:12:26,040 Speaker 1: we know which which standards it was compatible within eight 203 00:12:26,120 --> 00:12:29,360 Speaker 1: or two point eleven G became more and more common 204 00:12:30,679 --> 00:12:35,080 Speaker 1: and uh yeah, again had another problem with the fact 205 00:12:35,080 --> 00:12:39,040 Speaker 1: that it had the unregulated signal, just like eight O 206 00:12:39,160 --> 00:12:42,480 Speaker 1: two point eleven B did. So again there were there 207 00:12:42,600 --> 00:12:45,280 Speaker 1: was at least the potential for signals to have some 208 00:12:45,360 --> 00:12:47,720 Speaker 1: interference issues if you had a lot of other wireless 209 00:12:48,400 --> 00:12:51,040 Speaker 1: technologies running in the house, a lot of kids running 210 00:12:51,040 --> 00:12:57,040 Speaker 1: around on walkie talkies or you know exactly, I'll never 211 00:12:57,080 --> 00:13:00,840 Speaker 1: be over it. I'm never over kids over at my 212 00:13:00,880 --> 00:13:03,440 Speaker 1: house walking is that is just the most distracting thing 213 00:13:03,440 --> 00:13:05,280 Speaker 1: in the world, because especially because you don't have kids. 214 00:13:05,360 --> 00:13:07,720 Speaker 1: Yeah that who are you people? How did you get 215 00:13:07,720 --> 00:13:11,160 Speaker 1: into my house? Did Superman let you in? Has he 216 00:13:11,280 --> 00:13:15,320 Speaker 1: not gotten over the lead walls thing yet? You know? 217 00:13:15,520 --> 00:13:17,840 Speaker 1: Does that bring us up to two eleven N Yes? 218 00:13:17,880 --> 00:13:20,880 Speaker 1: And up until very very recently, this was not an 219 00:13:20,880 --> 00:13:25,280 Speaker 1: approved standard. However, UM, you know I have seen from 220 00:13:25,320 --> 00:13:31,040 Speaker 1: looking at the WiFi Alliances website, UM that at two 221 00:13:31,120 --> 00:13:36,240 Speaker 1: dot eleven and is actually an accepted specification at this time, UM, 222 00:13:36,280 --> 00:13:38,560 Speaker 1: which was supposed to happen this year. So you know 223 00:13:38,720 --> 00:13:40,880 Speaker 1: that those of you who are going, you know, okay, 224 00:13:40,880 --> 00:13:42,880 Speaker 1: so where's the surprise in that. No, that's that's uh, 225 00:13:42,960 --> 00:13:45,760 Speaker 1: that's right on time. They're supposed to do that this year. UM. 226 00:13:46,160 --> 00:13:50,480 Speaker 1: And uh, basically you're supposed to be able to get 227 00:13:50,520 --> 00:13:53,280 Speaker 1: a lot better range with at two dot eleven N 228 00:13:54,440 --> 00:13:57,160 Speaker 1: and speed for that matter, Um. That was one of 229 00:13:57,240 --> 00:14:00,120 Speaker 1: the things when I got UM. I got a new 230 00:14:00,360 --> 00:14:05,040 Speaker 1: wireless access point UM a few months ago, and it 231 00:14:05,120 --> 00:14:09,760 Speaker 1: had a proposed ATO two dot eleven and specification in it. Um. 232 00:14:09,800 --> 00:14:12,160 Speaker 1: You know, since I am sitting right next to or 233 00:14:12,200 --> 00:14:15,360 Speaker 1: almost right next to the the access point, I find 234 00:14:15,360 --> 00:14:19,880 Speaker 1: the ranges great. Yeah, but yeah, you are right next 235 00:14:19,920 --> 00:14:22,360 Speaker 1: to it as if you could actually plug your device 236 00:14:22,480 --> 00:14:25,240 Speaker 1: into it with a physical wire. How great the range 237 00:14:25,240 --> 00:14:28,720 Speaker 1: of details details? Actually, Um, when I was down the hall, 238 00:14:28,760 --> 00:14:31,120 Speaker 1: I actually moved the computer since then. UM, No, it 239 00:14:31,240 --> 00:14:33,200 Speaker 1: was it was giving me a much better range than 240 00:14:33,240 --> 00:14:35,960 Speaker 1: the old one. So UM, so you know it was 241 00:14:36,080 --> 00:14:39,840 Speaker 1: it was an improvement. Um. But yeah, the ATO two 242 00:14:39,920 --> 00:14:42,120 Speaker 1: dot eleven N is supposed to get you up to 243 00:14:42,160 --> 00:14:45,720 Speaker 1: a hundred forty megabits per second, which is pretty speedy. 244 00:14:45,840 --> 00:14:49,920 Speaker 1: Yeah that's considering I can't even get my my DSL 245 00:14:49,960 --> 00:14:55,920 Speaker 1: connection near that fast. So you were asking Mark about 246 00:14:56,040 --> 00:14:59,640 Speaker 1: the difficulties and networking. If you have different machines running 247 00:14:59,680 --> 00:15:03,320 Speaker 1: on different uh that require different standards, Yes, that will 248 00:15:03,360 --> 00:15:06,320 Speaker 1: be a problem because you have to have the right 249 00:15:06,600 --> 00:15:08,320 Speaker 1: It's it's like an antenna. You have to the right 250 00:15:08,400 --> 00:15:10,640 Speaker 1: kind of antenna to pick up the right kind of frequency. 251 00:15:10,800 --> 00:15:12,280 Speaker 1: And UM, it sort of depends on what kind of 252 00:15:12,320 --> 00:15:15,000 Speaker 1: card you have. Sorry interrupt, No, no no, go ahead, You 253 00:15:15,280 --> 00:15:18,720 Speaker 1: need to have something that will receive these signals in 254 00:15:18,760 --> 00:15:23,560 Speaker 1: your computer. UM and uh, you know, you can get 255 00:15:23,680 --> 00:15:26,040 Speaker 1: cards that are built right in and there are also 256 00:15:26,360 --> 00:15:28,560 Speaker 1: different kinds of cards that you can add on an 257 00:15:28,600 --> 00:15:32,000 Speaker 1: aftermarket depending on what kind of computer you have. UM. 258 00:15:32,040 --> 00:15:34,000 Speaker 1: And many of these cards can actually accept more than 259 00:15:34,040 --> 00:15:36,680 Speaker 1: one standard, like they'll they'll say it'll be you know, 260 00:15:36,720 --> 00:15:38,840 Speaker 1: you'll see like a B slash in or something like that, 261 00:15:38,960 --> 00:15:41,880 Speaker 1: or in slash G or Yeah. The chances are actually 262 00:15:41,880 --> 00:15:43,880 Speaker 1: if you go out and buy whatever off the shelf, 263 00:15:43,920 --> 00:15:46,920 Speaker 1: now it's going to be end compatible and backwards compatible 264 00:15:46,960 --> 00:15:50,360 Speaker 1: with the other three standards, which is great. I mean 265 00:15:50,440 --> 00:15:53,480 Speaker 1: if you don't have those compatible ones, then obviously if 266 00:15:53,480 --> 00:15:55,080 Speaker 1: you were to get if you were to have an 267 00:15:55,080 --> 00:15:59,040 Speaker 1: old eight O two point eleven G wireless card and 268 00:15:59,040 --> 00:16:01,040 Speaker 1: a laptop and you get an ETO two point eleven 269 00:16:01,360 --> 00:16:04,080 Speaker 1: in router, it's not going to do any good. Yeah, 270 00:16:04,120 --> 00:16:05,760 Speaker 1: you're not going to be able to access those faster 271 00:16:05,800 --> 00:16:09,440 Speaker 1: speeds because you're limited by it's kind of the weakest 272 00:16:09,800 --> 00:16:12,200 Speaker 1: link in the in the chain, kind of thing. Um, 273 00:16:12,240 --> 00:16:15,960 Speaker 1: you're you're limited by whatever you are, Your least fast 274 00:16:16,400 --> 00:16:19,400 Speaker 1: device is going to be uh in that in that 275 00:16:19,880 --> 00:16:23,520 Speaker 1: chain from router to computer. So yeah, it can cause 276 00:16:23,520 --> 00:16:25,240 Speaker 1: a little issue. It's not not as bad as you 277 00:16:25,320 --> 00:16:28,200 Speaker 1: might think because most things that most have routers and 278 00:16:28,440 --> 00:16:31,280 Speaker 1: modems that have been sold in the last few years 279 00:16:32,040 --> 00:16:33,720 Speaker 1: have really kind of ironed out a lot of the 280 00:16:33,720 --> 00:16:38,800 Speaker 1: compatibility issues. Um. But that's and you know, again, it's 281 00:16:38,880 --> 00:16:42,800 Speaker 1: kind of confusing because the standards do evolve over time 282 00:16:42,840 --> 00:16:46,800 Speaker 1: and the group is always working on different projects. That 283 00:16:47,040 --> 00:16:49,200 Speaker 1: mean that you know, within another five or six years 284 00:16:49,240 --> 00:16:51,360 Speaker 1: we may see something different. And not only that, but 285 00:16:51,440 --> 00:16:56,040 Speaker 1: we have other networking technologies that also come into play 286 00:16:56,080 --> 00:16:59,400 Speaker 1: that can be a little confusing. There's Bluetooth. Actually, it's 287 00:16:59,400 --> 00:17:01,600 Speaker 1: funny you mentioned that. I was getting ready to mention. 288 00:17:02,000 --> 00:17:04,520 Speaker 1: Please do um there are a couple different standards of 289 00:17:04,560 --> 00:17:09,080 Speaker 1: Bluetooth technology now. Bluetooth UM in general has a shorter 290 00:17:10,040 --> 00:17:12,479 Speaker 1: distance that you can use it a smaller range. Yes, 291 00:17:12,800 --> 00:17:17,840 Speaker 1: that's what I meant. Thank you for fixing that. Um. Hey, 292 00:17:17,920 --> 00:17:19,960 Speaker 1: who's the editor here? Yeah, well that would be me, 293 00:17:21,240 --> 00:17:24,600 Speaker 1: except when I'm talking this is why I add it. Um. Yeah, 294 00:17:24,640 --> 00:17:28,160 Speaker 1: it actually operates on frequency of two point four five 295 00:17:28,200 --> 00:17:32,240 Speaker 1: gigga hurts uh generally between two point four zero two 296 00:17:32,240 --> 00:17:34,560 Speaker 1: and two point four eight zero. If you're you know 297 00:17:34,640 --> 00:17:38,199 Speaker 1: split in hair for those notes. Yeah, yeah, and you 298 00:17:38,240 --> 00:17:42,240 Speaker 1: can you know, connect up to eight devices, um you 299 00:17:42,400 --> 00:17:44,920 Speaker 1: find I don't think a lot of people use Bluetooth 300 00:17:44,920 --> 00:17:47,119 Speaker 1: to connect a lot of devices to their computer. Maybe 301 00:17:47,160 --> 00:17:50,680 Speaker 1: like a wireless keyboard, er mouse maybe maybe or or yeah, 302 00:17:50,720 --> 00:17:53,600 Speaker 1: maybe a printer, sometimes your phone. I had a phone 303 00:17:53,600 --> 00:17:55,960 Speaker 1: that used Bluetooth, and I could drag and drop files 304 00:17:55,960 --> 00:17:57,760 Speaker 1: over like if I wanted to change ring tones, I 305 00:17:58,200 --> 00:18:01,399 Speaker 1: make an MP three and and you know, connect with it. 306 00:18:01,520 --> 00:18:04,199 Speaker 1: The promise of Bluetooth is really really cool in the 307 00:18:04,240 --> 00:18:08,600 Speaker 1: sense that you can have this personal area network and 308 00:18:09,119 --> 00:18:12,159 Speaker 1: you know, you the network would constantly be changing depending 309 00:18:12,200 --> 00:18:15,480 Speaker 1: on what devices you brought within the scope of that network. 310 00:18:15,760 --> 00:18:18,000 Speaker 1: So you can bring two devices together and it creates 311 00:18:18,000 --> 00:18:20,960 Speaker 1: one network. You bring those two devices toward a third device, 312 00:18:21,000 --> 00:18:23,600 Speaker 1: and you've got a new network. You take one device away. 313 00:18:23,920 --> 00:18:30,520 Speaker 1: I mean, it's a really flexible, uh and and dynamic system. 314 00:18:30,560 --> 00:18:33,719 Speaker 1: It's really really cool. I don't think anyone uses it 315 00:18:33,800 --> 00:18:37,600 Speaker 1: to the to its potential. Really, I mean, I don't 316 00:18:37,760 --> 00:18:40,800 Speaker 1: know one I know of uses Bluetooth. Like the people 317 00:18:40,840 --> 00:18:43,240 Speaker 1: who use Bluetooth that I know are using the very 318 00:18:43,320 --> 00:18:46,639 Speaker 1: very basic. So it's normally the headset and the and 319 00:18:46,760 --> 00:18:50,040 Speaker 1: the phone the handset. Um, that's pretty much it. Or 320 00:18:50,320 --> 00:18:52,760 Speaker 1: some of them are using some sort of handset and 321 00:18:52,880 --> 00:18:55,359 Speaker 1: a car like the car that's Bluetooth enabled, so that 322 00:18:55,400 --> 00:18:57,520 Speaker 1: the handset sinks with the car and they can listen 323 00:18:57,560 --> 00:19:01,160 Speaker 1: to music, or they can use a EPs system something 324 00:19:01,200 --> 00:19:05,080 Speaker 1: like that where or even use the cars sound system 325 00:19:05,119 --> 00:19:08,080 Speaker 1: for a if they're taking on calls or things of 326 00:19:08,080 --> 00:19:11,080 Speaker 1: that nature. But again it's still you're talking about a 327 00:19:11,080 --> 00:19:13,520 Speaker 1: two device maximum there as opposed to what the real 328 00:19:13,560 --> 00:19:15,879 Speaker 1: potential or Bluetooth is. I know somebody else is going 329 00:19:15,960 --> 00:19:18,119 Speaker 1: to write into now that I think about it. Another 330 00:19:18,119 --> 00:19:21,280 Speaker 1: device that you might see people use with their Bluetooth 331 00:19:21,359 --> 00:19:24,520 Speaker 1: enabled computer and be a set of headphones. Yeah, that's 332 00:19:24,520 --> 00:19:28,480 Speaker 1: that's pretty common. That's true. That's true. That's another common one. Um. 333 00:19:28,520 --> 00:19:33,320 Speaker 1: And another thing we're another kind of wireless standard. Was 334 00:19:33,359 --> 00:19:36,159 Speaker 1: going to talk about y max. So y max and 335 00:19:36,200 --> 00:19:39,720 Speaker 1: WiFi are two different things. They are not the you 336 00:19:39,880 --> 00:19:42,920 Speaker 1: often will see the media reference y max is saying 337 00:19:42,920 --> 00:19:47,120 Speaker 1: something like WiFi on steroids, which is I mean it's 338 00:19:47,119 --> 00:19:50,840 Speaker 1: an oversimplification. Yeah, it's definitely an oversimplification. Yes, y max 339 00:19:50,920 --> 00:19:54,840 Speaker 1: has a greater range than WiFi standards because it can 340 00:19:54,840 --> 00:19:58,280 Speaker 1: reach up to thirty miles right something like somewhere, and 341 00:19:58,280 --> 00:20:00,240 Speaker 1: and so y max has a much larger ring change. 342 00:20:00,440 --> 00:20:04,320 Speaker 1: And yes, you can get very fast uh down link 343 00:20:04,359 --> 00:20:06,840 Speaker 1: and uplink speeds on y max are relatively fast in 344 00:20:06,920 --> 00:20:09,919 Speaker 1: the way, about seventy megabits per seconds. So yeah, that's 345 00:20:09,960 --> 00:20:11,680 Speaker 1: pretty fast. I mean it's still not as fast, you know, 346 00:20:11,760 --> 00:20:15,280 Speaker 1: eight two point eleven and but yes, but you're not 347 00:20:15,320 --> 00:20:17,040 Speaker 1: going to get an eight or two down eleven and 348 00:20:17,400 --> 00:20:19,480 Speaker 1: much past oh I don't know, like the street in 349 00:20:19,520 --> 00:20:21,399 Speaker 1: front of your house. Yeah, you're not gonna That's the 350 00:20:21,440 --> 00:20:23,640 Speaker 1: other thing is that when we talk about these speeds, 351 00:20:23,680 --> 00:20:26,960 Speaker 1: we're talking about the maximum that those devices are capable 352 00:20:27,000 --> 00:20:29,720 Speaker 1: of generating. That doesn't necessarily mean that's the speed you 353 00:20:29,720 --> 00:20:32,920 Speaker 1: will experience. I will experience it based upon what your 354 00:20:32,960 --> 00:20:35,879 Speaker 1: I s P provides to you. Actually, when I was 355 00:20:35,880 --> 00:20:38,439 Speaker 1: saying a few minutes ago that my DSL struggles to 356 00:20:38,480 --> 00:20:41,280 Speaker 1: reach one point five megabits per second, you know, I 357 00:20:41,359 --> 00:20:43,640 Speaker 1: have a my router now is an eight or two 358 00:20:43,600 --> 00:20:47,359 Speaker 1: down eleven N I'm never gonna see anything faster than 359 00:20:47,440 --> 00:20:50,200 Speaker 1: one point five megabits per second because that's as fast 360 00:20:50,200 --> 00:20:53,080 Speaker 1: as it's gonna go. Now, if I connect with another computer, 361 00:20:53,960 --> 00:20:56,720 Speaker 1: if I have, you know, say my music library on 362 00:20:56,760 --> 00:20:58,240 Speaker 1: one computer I want to move it to another, I 363 00:20:58,240 --> 00:21:01,600 Speaker 1: can move it at that speed provided my cards in 364 00:21:01,640 --> 00:21:04,560 Speaker 1: both computers will reach that speed. So data transfers within 365 00:21:04,640 --> 00:21:08,120 Speaker 1: your network will go at at the ideal speed, right, 366 00:21:08,359 --> 00:21:12,280 Speaker 1: But data coming into or moving out of your network 367 00:21:12,400 --> 00:21:15,400 Speaker 1: to the outside world the Internet is going to move 368 00:21:15,480 --> 00:21:19,200 Speaker 1: at whatever speed the Internet service provider has designated or 369 00:21:19,400 --> 00:21:22,439 Speaker 1: what your current technology is capable of delivering. Yeah, so 370 00:21:22,480 --> 00:21:24,800 Speaker 1: the slowest point of connection in this case would be 371 00:21:24,840 --> 00:21:27,800 Speaker 1: my you know, pipe to the outside world, and everything 372 00:21:27,840 --> 00:21:31,160 Speaker 1: else is regulated by that, right, Everything inside super fast, 373 00:21:31,160 --> 00:21:35,000 Speaker 1: everything outside not so fast. Still fast, just not nearly 374 00:21:35,040 --> 00:21:37,040 Speaker 1: as fast as we sit there and think about how 375 00:21:37,040 --> 00:21:39,000 Speaker 1: slow this is. But then we'd sit there and like, hey, 376 00:21:39,000 --> 00:21:43,440 Speaker 1: do you remember that these bod modems. Okay, so it's 377 00:21:43,560 --> 00:21:45,920 Speaker 1: very fast compared to dial up modems. So y max 378 00:21:45,920 --> 00:21:47,920 Speaker 1: getting back to wy max um. Yeah, it's a totally 379 00:21:47,960 --> 00:21:51,720 Speaker 1: different set of standards. Uh to dot one six. I 380 00:21:51,800 --> 00:21:53,879 Speaker 1: like to I like to describe wy max the way 381 00:21:53,920 --> 00:21:56,920 Speaker 1: I tried to describe it to someone, uh, and how 382 00:21:56,960 --> 00:21:58,480 Speaker 1: it works if you if you want to try and 383 00:21:58,560 --> 00:22:02,720 Speaker 1: visualize it within an analogy is imagine a big circular 384 00:22:03,040 --> 00:22:07,800 Speaker 1: building that has a set number of doors along the 385 00:22:07,880 --> 00:22:10,880 Speaker 1: perimeter of the building. So we'll say forty forty doors 386 00:22:10,920 --> 00:22:14,000 Speaker 1: along the perimeter of the building. That means that forty 387 00:22:14,040 --> 00:22:16,880 Speaker 1: people can walk in and out of that building, carrying 388 00:22:16,880 --> 00:22:19,320 Speaker 1: stuff in and taking stuff out. So there's forty people 389 00:22:19,320 --> 00:22:21,520 Speaker 1: that would be people connecting to the white Max tower 390 00:22:21,840 --> 00:22:27,040 Speaker 1: to get data, so home networks necessary pretty much. Um 391 00:22:27,160 --> 00:22:30,480 Speaker 1: and after the after those forty doors are taken up 392 00:22:30,520 --> 00:22:33,240 Speaker 1: by the various people, that's it. It's not going to 393 00:22:33,280 --> 00:22:36,040 Speaker 1: accept any more people on that tower, which means that 394 00:22:36,160 --> 00:22:39,640 Speaker 1: every single person is going to still get the speeds 395 00:22:39,640 --> 00:22:43,040 Speaker 1: that they were promised. You know, there's no choking because 396 00:22:43,080 --> 00:22:46,840 Speaker 1: there's no bottleneck there because the tower has cut off 397 00:22:46,880 --> 00:22:49,520 Speaker 1: the number of people who can connect to it. WiFi 398 00:22:49,600 --> 00:22:52,200 Speaker 1: is different. WiFi people just keep piling in and out. 399 00:22:52,240 --> 00:22:54,960 Speaker 1: There's like one big set of doors, and everyone is 400 00:22:54,960 --> 00:22:56,320 Speaker 1: trying to get in and out of that set of 401 00:22:56,359 --> 00:22:59,040 Speaker 1: doors at the same time. So the more people are 402 00:22:59,040 --> 00:23:02,480 Speaker 1: trying to access a WiFi spot, the slower you're going 403 00:23:02,520 --> 00:23:05,119 Speaker 1: to experience, the slower the data rates will be, slower 404 00:23:05,200 --> 00:23:09,119 Speaker 1: data transfer rates will be because it does not limit 405 00:23:09,200 --> 00:23:12,119 Speaker 1: the number like y MAX does, so it's a different 406 00:23:12,160 --> 00:23:15,240 Speaker 1: approach really. UM and y max, of course, is just 407 00:23:15,400 --> 00:23:18,200 Speaker 1: one of the four G solutions that we're looking at 408 00:23:18,320 --> 00:23:20,960 Speaker 1: in the in the future. There are others as well, 409 00:23:21,119 --> 00:23:24,439 Speaker 1: such as LTE, which is long term evolution. Looks it 410 00:23:24,480 --> 00:23:26,080 Speaker 1: looks like those two are going to be fighting it 411 00:23:26,119 --> 00:23:29,560 Speaker 1: out to be that the four G standard. Depending on 412 00:23:29,800 --> 00:23:34,840 Speaker 1: whom you ask and where and what what company you 413 00:23:34,920 --> 00:23:37,200 Speaker 1: happen to be working for that is backing which standard. 414 00:23:37,440 --> 00:23:40,120 Speaker 1: Right here in Atlanta we're actually seeing y max now 415 00:23:40,520 --> 00:23:43,359 Speaker 1: UM and a few other cities in the United States 416 00:23:43,440 --> 00:23:46,320 Speaker 1: also have y max now and more are expected to 417 00:23:46,359 --> 00:23:49,679 Speaker 1: get it within the next year. Yeah, but LT is 418 00:23:49,720 --> 00:23:52,040 Speaker 1: on its way, I'm I'm pretty sure. Yeah. And it's 419 00:23:52,080 --> 00:23:55,720 Speaker 1: also that's also being giving the UH the fast track 420 00:23:55,760 --> 00:23:58,560 Speaker 1: and development. I do want to clarify though, just to 421 00:23:58,600 --> 00:24:01,760 Speaker 1: make certain that everyone understand hands that if you have 422 00:24:01,840 --> 00:24:04,240 Speaker 1: a Wi Fi card A to two down eleven, a 423 00:24:04,359 --> 00:24:07,240 Speaker 1: b G or n UM, those may or may not 424 00:24:07,359 --> 00:24:11,760 Speaker 1: be compatible with you know, a a particular card or 425 00:24:12,160 --> 00:24:15,560 Speaker 1: you know, some plug in for your computer. But Bluetooth 426 00:24:15,600 --> 00:24:18,400 Speaker 1: and Wi max are going to require their own separate thing. 427 00:24:18,680 --> 00:24:22,040 Speaker 1: They're not they're not related. You can't get one card, 428 00:24:22,280 --> 00:24:24,359 Speaker 1: as far as I know, you can't get one card 429 00:24:24,359 --> 00:24:27,119 Speaker 1: that will get all of those frequencies, you know, and 430 00:24:27,200 --> 00:24:29,080 Speaker 1: one thing that you can plug into your machinery looking 431 00:24:29,119 --> 00:24:33,920 Speaker 1: at probably three. Yeah, although I guess you could argue 432 00:24:33,960 --> 00:24:38,280 Speaker 1: that y max could replace WiFi, except unless you're actually well, 433 00:24:38,320 --> 00:24:40,280 Speaker 1: if you're doing home networking stuff, if you're trying to 434 00:24:40,280 --> 00:24:43,960 Speaker 1: actually transfer data between machines in your home network, then 435 00:24:44,000 --> 00:24:47,400 Speaker 1: you will need something. Because wy max it's it's reporting 436 00:24:47,440 --> 00:24:50,600 Speaker 1: back to the internet service provider. It's not it's not 437 00:24:50,640 --> 00:24:55,600 Speaker 1: a home networking solution. Well, okay, that's actually a good point, because, um, 438 00:24:55,720 --> 00:25:00,040 Speaker 1: the the particular y max provider that is advertising in 439 00:25:00,040 --> 00:25:02,359 Speaker 1: the Atlanta area shows off that you can have your 440 00:25:02,440 --> 00:25:06,120 Speaker 1: laptop with you and get access anywhere and you could 441 00:25:06,119 --> 00:25:07,640 Speaker 1: be on the bus, you could be you know, at 442 00:25:07,640 --> 00:25:09,800 Speaker 1: an sidewalk cafe, you could be at your home and 443 00:25:09,800 --> 00:25:13,360 Speaker 1: you're still going to get your winmax speed. Well that's great. However, 444 00:25:13,600 --> 00:25:15,760 Speaker 1: if you're using basically what they're showing off as a 445 00:25:15,760 --> 00:25:20,600 Speaker 1: as a dongle type card modem thing. Um, that's the 446 00:25:20,640 --> 00:25:24,720 Speaker 1: scientific term for it, modem card thing. Yes, yes, I 447 00:25:24,720 --> 00:25:28,760 Speaker 1: think it's on the box. Okay, okay, So anyway, you 448 00:25:28,800 --> 00:25:30,280 Speaker 1: plug the thing in the side of your computer, you 449 00:25:30,280 --> 00:25:32,720 Speaker 1: can get and you can go anywhere. What happens if 450 00:25:32,720 --> 00:25:35,360 Speaker 1: you go home and you want to hook up, say 451 00:25:35,520 --> 00:25:39,240 Speaker 1: your spouse is computer, Well, now you kind of need 452 00:25:39,280 --> 00:25:42,399 Speaker 1: the internet. We'll see that's what's she going to do 453 00:25:42,440 --> 00:25:47,240 Speaker 1: with it? Okay, so then you're stuck. That's no, no 454 00:25:47,320 --> 00:25:49,480 Speaker 1: more home networking if all you have is that one 455 00:25:49,560 --> 00:25:53,919 Speaker 1: type of you know, connectivity. You know, they offer this 456 00:25:54,000 --> 00:25:56,679 Speaker 1: The m X provider also offers a home modem and 457 00:25:56,720 --> 00:25:58,800 Speaker 1: then you could plug that into wave WiFi connection. But 458 00:25:58,840 --> 00:26:01,040 Speaker 1: if you want to get you know, the Wi Max 459 00:26:01,480 --> 00:26:04,760 Speaker 1: all around town, you're going to have to have the portable. Yeah, 460 00:26:05,400 --> 00:26:07,919 Speaker 1: that's that's a difference. Does have night actually have a 461 00:26:07,920 --> 00:26:11,120 Speaker 1: WiMAX and a WiFi Well, yeah, they Yeah, that's true, 462 00:26:11,200 --> 00:26:13,680 Speaker 1: that's true. I've seen I've seen the packages I've seen 463 00:26:13,760 --> 00:26:16,440 Speaker 1: usually involved you can get one of each. You can 464 00:26:16,440 --> 00:26:18,840 Speaker 1: get one that's the home solution where you you hook 465 00:26:18,920 --> 00:26:21,520 Speaker 1: that up to your router. So you have to buy 466 00:26:21,600 --> 00:26:25,840 Speaker 1: both of them, Yes, but but there's some that's like 467 00:26:25,880 --> 00:26:28,679 Speaker 1: a package deal though, so you're getting a discount as 468 00:26:28,720 --> 00:26:33,200 Speaker 1: opposed to if you were buying each separately. Yes, yes, 469 00:26:33,640 --> 00:26:35,960 Speaker 1: so yes, you would still have to have your wireless router, 470 00:26:36,560 --> 00:26:38,560 Speaker 1: which would that's working on the WiFi if you want 471 00:26:38,560 --> 00:26:40,880 Speaker 1: to hook up all your computers, yes, exactly, and within 472 00:26:40,960 --> 00:26:43,040 Speaker 1: your home, and then you would have the y max 473 00:26:43,080 --> 00:26:48,400 Speaker 1: dongle for whichever computer you have designated as the the 474 00:26:48,440 --> 00:26:50,720 Speaker 1: main one whenever you're heading outside the house and you 475 00:26:50,760 --> 00:26:52,960 Speaker 1: want to be able to hook directly to your I 476 00:26:53,080 --> 00:26:54,320 Speaker 1: s P. The nice thing about that is you don't 477 00:26:54,359 --> 00:26:57,120 Speaker 1: have to pay for any other like WiFi services, any 478 00:26:57,160 --> 00:26:59,520 Speaker 1: hotspots or anything like that, and you don't have to 479 00:26:59,640 --> 00:27:01,600 Speaker 1: you don't have to depend upon no yeah, because with 480 00:27:01,640 --> 00:27:04,919 Speaker 1: the yeah, you're connecting right to the Wi max thing tower, 481 00:27:05,040 --> 00:27:09,240 Speaker 1: not not to WiFi UH networks. And so I know 482 00:27:09,320 --> 00:27:12,520 Speaker 1: that's a big problem for us, us being me and 483 00:27:12,560 --> 00:27:18,080 Speaker 1: my wife, we when we're traveling around UH town, we 484 00:27:18,160 --> 00:27:20,320 Speaker 1: have to hope that wherever we're going has a WiFi 485 00:27:20,359 --> 00:27:23,520 Speaker 1: network and that that hopefully it's a WiFi network where 486 00:27:23,520 --> 00:27:26,000 Speaker 1: we don't have to pay extra to get attached to it, 487 00:27:26,000 --> 00:27:29,159 Speaker 1: because when you're already paying uh an internet service provider 488 00:27:29,200 --> 00:27:31,240 Speaker 1: to get access to the internet, you kind of hate 489 00:27:31,280 --> 00:27:32,959 Speaker 1: the thought of having to pay again because you're like, 490 00:27:33,160 --> 00:27:36,399 Speaker 1: if we were home, we could access this based on 491 00:27:36,440 --> 00:27:39,680 Speaker 1: our plan, we wouldn't have to pay extra. So yeah, 492 00:27:39,680 --> 00:27:45,720 Speaker 1: we get a little yeah mightily miffed. Great was the 493 00:27:45,760 --> 00:27:49,879 Speaker 1: message thereof all, Right, well, I think that that pretty 494 00:27:49,920 --> 00:27:52,520 Speaker 1: much covers the whole WiFi angle. Yeah. I'm sure we've 495 00:27:52,560 --> 00:27:55,480 Speaker 1: confused everyone by now. I know I'm more confused than 496 00:27:55,520 --> 00:28:01,359 Speaker 1: when we started, so good job. Um, well, you know, 497 00:28:01,600 --> 00:28:03,800 Speaker 1: I guess that means that it's time to wrap things 498 00:28:03,920 --> 00:28:10,400 Speaker 1: up with a little a listener mail. This listener mail 499 00:28:10,440 --> 00:28:13,399 Speaker 1: comes from kse. Hey, guys, I love the podcast. I 500 00:28:13,440 --> 00:28:15,600 Speaker 1: had a quick question for you. I've heard that Mac 501 00:28:15,600 --> 00:28:19,040 Speaker 1: and Linux operating systems don't get viruses like Windows computers do. 502 00:28:19,320 --> 00:28:21,040 Speaker 1: As far as I can tell, I haven't even heard 503 00:28:21,040 --> 00:28:24,240 Speaker 1: of a virus protection software from my Leopard running operating system. 504 00:28:24,359 --> 00:28:26,760 Speaker 1: Is this because the Unix base that Mac and Lenox 505 00:28:26,800 --> 00:28:29,440 Speaker 1: were built on is less susceptible, or because Windows is 506 00:28:29,480 --> 00:28:31,600 Speaker 1: a little easier to target because of how mainstream they 507 00:28:31,600 --> 00:28:33,800 Speaker 1: are operating system is keep up the good work, and 508 00:28:33,840 --> 00:28:37,040 Speaker 1: I would love to hear the answer to this sometime. Okay, See, 509 00:28:37,040 --> 00:28:40,080 Speaker 1: first of all, let's let's address a couple of things. Uh. 510 00:28:40,280 --> 00:28:44,200 Speaker 1: Linux does not have a Unix base. Technically, it is not. 511 00:28:44,680 --> 00:28:48,840 Speaker 1: It is it was inspired Lennox was inspired by Unix, 512 00:28:48,960 --> 00:28:52,000 Speaker 1: or rather we should say Linus was inspired by Unix. 513 00:28:52,280 --> 00:28:56,400 Speaker 1: Actually he was inspired by Umnix Minix, which in turn 514 00:28:56,560 --> 00:28:59,960 Speaker 1: was a a kind of open source alternative to Unix. 515 00:29:00,280 --> 00:29:02,680 Speaker 1: Yes see, you have Unix, you have the open source 516 00:29:02,720 --> 00:29:05,360 Speaker 1: alternative to Unix called Minix. You had Linus Torvalds, who 517 00:29:05,360 --> 00:29:09,480 Speaker 1: was then inspired by Minix to create Linux. So let's 518 00:29:09,520 --> 00:29:13,240 Speaker 1: get that all the way. Um As for are they 519 00:29:13,360 --> 00:29:19,360 Speaker 1: just naturally less susceptible? Not technically, I mean there, it's 520 00:29:19,440 --> 00:29:24,080 Speaker 1: it's more challenging to create the uh something that exploits 521 00:29:24,080 --> 00:29:28,320 Speaker 1: a vulnerability in Linux or Mac because you've got, within 522 00:29:28,360 --> 00:29:30,880 Speaker 1: the case of Linux, you've got a community that is 523 00:29:30,880 --> 00:29:33,680 Speaker 1: dedicated to finding these things out and fixing them before 524 00:29:33,680 --> 00:29:36,640 Speaker 1: they become problems. It doesn't mean that it's impossible. It 525 00:29:36,640 --> 00:29:39,520 Speaker 1: just means it's more challenging because you've you know, you've 526 00:29:39,520 --> 00:29:44,200 Speaker 1: got the entire worldwide Linux community working on this stuff. Um, 527 00:29:44,240 --> 00:29:47,000 Speaker 1: even though there are various distributions and each distribution is 528 00:29:47,040 --> 00:29:51,000 Speaker 1: slightly different from each other distribution Mac, you've got a 529 00:29:51,040 --> 00:29:55,400 Speaker 1: closed system which is harder to get into and learn 530 00:29:55,480 --> 00:29:59,600 Speaker 1: how that works because Apple controls the whole Mac situation 531 00:29:59,680 --> 00:30:03,880 Speaker 1: from the hardware to the operating system. Even so, it 532 00:30:04,000 --> 00:30:08,600 Speaker 1: is possible to create uh programs that exploit vulnerabilities. We've 533 00:30:08,640 --> 00:30:12,320 Speaker 1: seen that both in max and in Linux systems. Recently, 534 00:30:12,400 --> 00:30:15,160 Speaker 1: we've seen some that went as that that even exploit 535 00:30:15,240 --> 00:30:20,480 Speaker 1: vulnerabilities or could exploit vulnerability within the Linux kernel itself. Um, 536 00:30:20,600 --> 00:30:25,200 Speaker 1: that doesn't mean that there as vulnerable as a Windows system. 537 00:30:25,560 --> 00:30:28,080 Speaker 1: Your question of is Windows more vulnerable because it's more 538 00:30:28,120 --> 00:30:31,160 Speaker 1: popular In a way, Yes, it's certainly more popular with 539 00:30:31,200 --> 00:30:36,000 Speaker 1: hackers for one thing. I mean it's it's more accessible. Also, 540 00:30:36,240 --> 00:30:39,200 Speaker 1: more people are using Windows, So therefore your target is 541 00:30:39,240 --> 00:30:42,000 Speaker 1: You've got a target rich environment is what our friends 542 00:30:42,000 --> 00:30:44,640 Speaker 1: in the military would call it. It's it means that 543 00:30:44,680 --> 00:30:48,080 Speaker 1: if you do write some malicious software, you're gonna hit 544 00:30:48,240 --> 00:30:50,360 Speaker 1: way more victims. If you do it for Windows, then 545 00:30:50,360 --> 00:30:52,520 Speaker 1: you're gonna hit if you use it for Macrolnox just 546 00:30:52,600 --> 00:30:55,280 Speaker 1: because there are more people using Windows out there than 547 00:30:55,640 --> 00:30:57,880 Speaker 1: the alternatives. But if you look at some of the 548 00:30:57,920 --> 00:31:02,400 Speaker 1: vulnerabilities that exploit servers off where that's all Linux based stuff. Yeah, 549 00:31:02,440 --> 00:31:04,520 Speaker 1: I mean almost all of it, not not all of it, 550 00:31:04,600 --> 00:31:06,680 Speaker 1: don't write me, I know, not all of it, but 551 00:31:06,880 --> 00:31:10,200 Speaker 1: a great deal of it. So it is possible, it's 552 00:31:10,240 --> 00:31:13,560 Speaker 1: just not as common. Yeah, And there are there are 553 00:31:13,600 --> 00:31:18,440 Speaker 1: a couple of security providers who have written uh mac 554 00:31:18,600 --> 00:31:22,320 Speaker 1: virus software and has been out for many many years now. Um. 555 00:31:22,920 --> 00:31:25,400 Speaker 1: Actually I think snow Leppard came with some anti virus 556 00:31:26,040 --> 00:31:30,280 Speaker 1: in under the hood. Yeah, it's it's sort of invisible. Actually, 557 00:31:30,720 --> 00:31:32,600 Speaker 1: not like I've actually noticed it, let me put it 558 00:31:32,640 --> 00:31:36,520 Speaker 1: that way. Um, but but yeah, I mean, and and 559 00:31:36,560 --> 00:31:40,120 Speaker 1: the one, the one I would say that is arguable, argue, 560 00:31:40,160 --> 00:31:44,040 Speaker 1: I believe the largest. Um it's a company called Intigo. 561 00:31:44,080 --> 00:31:49,080 Speaker 1: And they're the ones who always draw attention to vulnerabilities 562 00:31:49,120 --> 00:31:52,040 Speaker 1: when they are pointed out, and um, they usually get 563 00:31:52,240 --> 00:31:56,000 Speaker 1: sort of picked on, uh and in some of the 564 00:31:56,040 --> 00:31:58,440 Speaker 1: stuff that I've read because they go, oh, yeah, well 565 00:31:58,560 --> 00:32:00,320 Speaker 1: you guys are the ones writing this saw where of 566 00:32:00,320 --> 00:32:05,000 Speaker 1: course that's what happens when Symantec or or McAfee also 567 00:32:05,040 --> 00:32:07,120 Speaker 1: points out that there are vulnerabilities out there. I mean, 568 00:32:07,160 --> 00:32:11,640 Speaker 1: they have a vested interest in keeping that um in mind. 569 00:32:11,720 --> 00:32:13,320 Speaker 1: But a lot of and a lot of cases to 570 00:32:13,400 --> 00:32:19,320 Speaker 1: the Mac stuff scans for Windows uh UM malware as well, 571 00:32:19,440 --> 00:32:21,480 Speaker 1: which is useful if you're running an Intel MAAC and 572 00:32:21,520 --> 00:32:23,880 Speaker 1: happen to be running and happen to have an installation 573 00:32:23,880 --> 00:32:27,680 Speaker 1: of Windows and the Mac operating system on your Mac UM. 574 00:32:27,760 --> 00:32:30,040 Speaker 1: So you know, it can be handy. But a lot 575 00:32:30,040 --> 00:32:32,880 Speaker 1: of people in the Mac world still believe that their 576 00:32:33,000 --> 00:32:37,520 Speaker 1: position is very secure and do not use any virus 577 00:32:37,560 --> 00:32:39,760 Speaker 1: software right now. That does not mean if you have 578 00:32:39,800 --> 00:32:42,040 Speaker 1: a Mac or Linux machine that you should go clicking 579 00:32:42,040 --> 00:32:44,800 Speaker 1: on every single link and and installing every single application 580 00:32:44,840 --> 00:32:48,160 Speaker 1: you come across, because you never know when that that 581 00:32:48,480 --> 00:32:52,200 Speaker 1: vulnerability will be discovered and exploited. Uh. Here's the tricky 582 00:32:52,240 --> 00:32:55,280 Speaker 1: thing about hackers who find vulnerabilities. Some of them don't 583 00:32:55,320 --> 00:32:58,480 Speaker 1: make it public knowledge, and so it may be you 584 00:32:58,480 --> 00:33:01,080 Speaker 1: know that it's constantly a game of let's catch up 585 00:33:01,080 --> 00:33:04,240 Speaker 1: to what the hackers know and uh and then patch it. 586 00:33:04,520 --> 00:33:07,920 Speaker 1: So just be careful. Uh yeah, Max and Lennox machines 587 00:33:07,960 --> 00:33:10,920 Speaker 1: aren't gonna experience them as often as windows are uh, 588 00:33:11,280 --> 00:33:14,520 Speaker 1: just in general, but it's it's not outside the realm 589 00:33:14,520 --> 00:33:21,280 Speaker 1: of possibility. I hope you enjoyed that look back. I 590 00:33:21,280 --> 00:33:24,440 Speaker 1: will remind you that things have changed quite a bit 591 00:33:24,480 --> 00:33:27,720 Speaker 1: since two thousand nine. We have seen improvements in both 592 00:33:27,840 --> 00:33:30,880 Speaker 1: y Max and WiFi over that time, as well as 593 00:33:30,960 --> 00:33:36,120 Speaker 1: improvements to Bluetooth and other wireless transmission technologies. No big 594 00:33:36,120 --> 00:33:38,560 Speaker 1: surprise there. You would imagine that we would continue to 595 00:33:38,640 --> 00:33:41,560 Speaker 1: improve on those. But I hope that gives you the 596 00:33:41,600 --> 00:33:44,640 Speaker 1: basics that you needed to understand the differences and what 597 00:33:44,760 --> 00:33:47,800 Speaker 1: these things do and what they're intended for. And if 598 00:33:47,840 --> 00:33:51,000 Speaker 1: you guys have any suggestions for future episodes, First of all, 599 00:33:51,120 --> 00:33:53,680 Speaker 1: I'm gonna be back in the studio very soon, so 600 00:33:53,880 --> 00:33:56,080 Speaker 1: definitely let me know what you want to hear about, 601 00:33:56,120 --> 00:33:58,280 Speaker 1: because I'll be ready to record as soon as I 602 00:33:58,320 --> 00:34:02,000 Speaker 1: get back.

You would love 605 00:34:07,640 --> 00:34:09,680 Speaker 1: to have a guest host come in and talk about 606 00:34:09,680 --> 00:34:12,880 Speaker 1: a particular subject, let me know. Send me an email 607 00:34:12,920 --> 00:34:16,040 Speaker 1: that addresses tech stuff at how stuff works dot com. 608 00:34:16,120 --> 00:34:18,920 Speaker 1: Will draw me a line on Twitter, Facebook, for Tumbler. 609 00:34:18,960 --> 00:34:22,000 Speaker 1: At all three, I am tech stuff hs W, and 610 00:34:22,040 --> 00:34:29,680 Speaker 1: I'll talk to you again really soon.
