WEBVTT - TechStuff Classics: The types of WiFi 0:00:04.240 --> 0:00:07.440 Get in text with technology with tex Stuff from Hastaf. 0:00:11.680 --> 0:00:14.920 Hey there, and welcome to tech Stuff. I'm Jonathan Strickland. 0:00:15.200 --> 0:00:19.680 I'm still on vacation, vacating which means that we're going 0:00:19.720 --> 0:00:24.439 to enjoy another classic episode of tech Stuff, but we're 0:00:24.480 --> 0:00:27.240 doing so for a specific reason because of a little 0:00:28.040 --> 0:00:31.840 listener mail. And this comes from Troy, who says, good afternoon. 0:00:31.920 --> 0:00:34.159 I've recently started to listen to your podcast as my 0:00:34.280 --> 0:00:37.640 tech interests begin to grow. I was hoping you could 0:00:37.640 --> 0:00:40.479 do an episode on WiFi versus Y Max would be 0:00:40.520 --> 0:00:44.120 great to learn about that. Well, Troy, way back in 0:00:44.159 --> 0:00:48.080 the day, I'm talking November of two thousand nine, Chris Pallette, 0:00:48.120 --> 0:00:51.960 my original co host, and I talked about WiFi and 0:00:52.000 --> 0:00:54.680 the different types of WiFi, and we also talked about 0:00:54.680 --> 0:00:57.880 Wi Max, which is not a type of WiFi. We 0:00:58.040 --> 0:01:01.120 grouped it under there because it was the easiest way 0:01:01.160 --> 0:01:04.400 to explain it to people who are unfamiliar with it. 0:01:04.760 --> 0:01:09.360 But I regret actually calling the episode the different types 0:01:09.400 --> 0:01:12.440 of WiFi, because why that's that's that's misleading. Why Max 0:01:12.480 --> 0:01:14.920 and WiFi are two different things. There are actually two 0:01:14.959 --> 0:01:20.399 different communications standards designed to transmit data wirelessly, So you 0:01:20.440 --> 0:01:23.320 can think of it as two different approaches to accomplish 0:01:23.600 --> 0:01:28.880 similar goals. Now, why MAX can transmit up to about 0:01:28.880 --> 0:01:32.360 a gigabit per second for fixed stations, in other words, 0:01:32.400 --> 0:01:34.840 a station that is in a fixed location, it's not 0:01:34.920 --> 0:01:38.920 moving around, and it can also transmit this at a 0:01:39.040 --> 0:01:43.120 much wider area than say WiFi could. Uh. That is 0:01:43.880 --> 0:01:49.120 why why Max is really being used in municipal wireless data. 0:01:49.560 --> 0:01:52.600 So in other words, it's it's kind of a a 0:01:52.640 --> 0:01:57.560 replacement for wired connections. You wouldn't use cables instead, you 0:01:57.560 --> 0:02:00.480 would have these towers that would transmit why MAX signals 0:02:00.960 --> 0:02:05.320 using this specific standard, and you could then provide internet 0:02:05.320 --> 0:02:09.760 connectivity to different to a large area, whereas WiFi tends 0:02:09.800 --> 0:02:13.000 to be much more localized, it doesn't have as broad 0:02:13.040 --> 0:02:16.480 a transmission range, but it can also go really fast. 0:02:16.880 --> 0:02:20.160 In fact, the the eight O two dot eleven a 0:02:20.400 --> 0:02:24.640 C standard is on the five giga Hurts band of frequencies, 0:02:24.680 --> 0:02:27.920 because WiFi uses two different frequency bands depending upon the 0:02:27.919 --> 0:02:32.040 standard you're using, and can also reach a gigabit per 0:02:32.080 --> 0:02:36.560 second or even theoretically faster than that. So the two 0:02:36.560 --> 0:02:39.480 are able to transmit data at similar speeds, but doing 0:02:39.520 --> 0:02:43.000 so in a different way, and I will now transfer 0:02:43.120 --> 0:02:47.359 this over to the episode where Chris and I talked 0:02:47.480 --> 0:02:50.720 more about these different types. Keeping in mind this goes 0:02:50.760 --> 0:02:54.040 back to two thousand nine and the standards have evolved 0:02:54.400 --> 0:03:02.280 considerably since then, So enjoy this episode. We thought we'd 0:03:02.280 --> 0:03:05.760 talked a little bit about the different kinds of wireless 0:03:06.440 --> 0:03:09.120 networks out there are the ones that use the various 0:03:09.280 --> 0:03:13.200 standards set out by our good friends at the Triple E, 0:03:13.600 --> 0:03:20.160 or as I always like to call them, a yeah right, Yeah, 0:03:20.320 --> 0:03:24.880 you know, early early networks were sort of like tin 0:03:24.960 --> 0:03:27.720 cans with the string between them. This sort of makes 0:03:27.760 --> 0:03:30.959 this string virtual. Yeah, there you go. That's all you 0:03:31.000 --> 0:03:38.360 need to know. There's the whole we're gonna alright, So anyway, uh, 0:03:38.640 --> 0:03:41.480 we're talking about a set of standards that in general 0:03:41.760 --> 0:03:45.920 fall under the designation eight zero two point one one. 0:03:46.320 --> 0:03:49.480 Doesn't that easy? Yeah, well it's it's the most those 0:03:49.520 --> 0:03:55.520 are the most common frequency variations of wireless networking. So 0:03:56.960 --> 0:04:00.400 the way you h you'll see on things like outers 0:04:00.400 --> 0:04:03.000 and modems and stuff. You'll see this number followed by 0:04:03.040 --> 0:04:06.400 a letter, and that tells you which of the specific 0:04:06.440 --> 0:04:08.800 sets of standards you're working with. Now you've got to 0:04:08.920 --> 0:04:12.560 understand what I was getting ready to correct myself because 0:04:12.600 --> 0:04:16.400 I said, and that's not a frequency, no, No, it's 0:04:16.480 --> 0:04:19.400 just a designation. Is a designation? Yes, so so the 0:04:19.520 --> 0:04:24.599 I triple ey. They work on various designations for different 0:04:25.120 --> 0:04:28.279 UM networking solutions, and with the eight to two point 0:04:28.360 --> 0:04:31.000 one one, you have different working groups all working on 0:04:31.080 --> 0:04:35.679 different sets of standards to try and create the most 0:04:35.800 --> 0:04:41.080 stable and reliable form of wireless networking in this case 0:04:41.080 --> 0:04:44.880 wireless networking UM. And it's it's a little confusing because 0:04:44.960 --> 0:04:47.280 you have all these different groups working on working from 0:04:47.279 --> 0:04:50.760 the same basic set of standards, but they're all tweaking 0:04:50.800 --> 0:04:53.559 them in different ways to try and get different kinds 0:04:53.560 --> 0:04:57.320 of performance out of them. So let's try and go 0:04:57.440 --> 0:04:59.880 through some of these. It's really kind of complex, but 0:05:00.120 --> 0:05:03.600 um yeah. One of the things to uh that's kind 0:05:03.600 --> 0:05:07.839 of interesting about these different standards is, UH, as we 0:05:07.880 --> 0:05:10.280 start going through them, if we are going through them 0:05:10.279 --> 0:05:13.520 in alphabetical order, you will find that they do not 0:05:13.760 --> 0:05:18.200 necessarily uh go start from the bottom up, like if 0:05:18.240 --> 0:05:22.719 we start with eight eight O two dot eleven A. UH. 0:05:22.760 --> 0:05:26.760 This actually operates on the five gigga hurts frequency and 0:05:27.040 --> 0:05:31.919 can carry up to fifty four megabets of data per second. Uh, 0:05:32.040 --> 0:05:34.760 in contrast at two dot eleven B you'd figure to 0:05:34.800 --> 0:05:38.320 be faster. No, actually it's not. It operates at the 0:05:38.360 --> 0:05:41.760 two point four gigga hurts frequency and only can handle 0:05:41.800 --> 0:05:45.360 eleven megabits of data per second. And that's just one 0:05:45.400 --> 0:05:47.920 of those things that makes it so confusing is you 0:05:47.920 --> 0:05:50.039 you'd figure there would be a logical progression there, and 0:05:50.080 --> 0:05:53.680 there's not necessarily one. Yeah, so what do you think 0:05:53.680 --> 0:05:55.920 should we go by just by letter even though it's 0:05:55.920 --> 0:05:58.599 not logical progression necessarily, but just to make it easier 0:05:58.640 --> 0:06:01.520 to move from one to the other. Those two, those 0:06:01.520 --> 0:06:04.040 two do fit well together because they were the first 0:06:04.200 --> 0:06:10.280 two very common standards, at least in my experience. Well. 0:06:10.320 --> 0:06:16.080 ATO two point eleven B uses UH unregulated radio signal 0:06:16.080 --> 0:06:21.520 frequencies in the two point four gigga hurts range. So uh, 0:06:21.800 --> 0:06:24.120 here's something. Here's some things about the ATO two point 0:06:24.160 --> 0:06:29.520 one one B set standards. It's single ranges is pretty good, 0:06:30.240 --> 0:06:32.479 um in the two point four gigga Hurts range, and 0:06:32.680 --> 0:06:36.280 it's not going to have problems with obstructions that some 0:06:36.320 --> 0:06:39.760 other frequencies do. So, in other words, you might be 0:06:39.839 --> 0:06:43.840 able to use this kind of signal through walls things 0:06:43.880 --> 0:06:46.320 like that, you don't have to worry about losing signal 0:06:46.360 --> 0:06:49.560 as soon as you turn a corner some UH from 0:06:49.600 --> 0:06:54.040 the source of the the frequency UM, and it's not 0:06:54.400 --> 0:06:58.560 very expensive. The range is pretty good, UM, but it's 0:06:59.120 --> 0:07:01.920 not a very it's not very fast, as you pointed out, 0:07:02.360 --> 0:07:04.760 you know, compared to eight to two point eleven A. 0:07:05.440 --> 0:07:11.800 It's it's fairly slow. UM. And because it's an unregulated frequency, 0:07:12.160 --> 0:07:16.320 some other appliances that generate radio frequencies can cause interference 0:07:16.480 --> 0:07:20.920 within that wireless UH frequency because you have to remember 0:07:21.880 --> 0:07:24.800 the computer you're using whatever, Like if you have a 0:07:24.840 --> 0:07:30.040 wireless router that's broadcasting WiFi on this set of standards, 0:07:30.400 --> 0:07:33.560 if it's using unregulated radio frequencies, that means that it 0:07:33.600 --> 0:07:36.960 can fall within a wider range, and that things that 0:07:37.360 --> 0:07:40.520 also generate radio frequencies within that range. When you're using 0:07:40.560 --> 0:07:42.679 your computer, your computer doesn't know which one of those 0:07:42.760 --> 0:07:45.040 which of those signals are coming from your router and 0:07:45.080 --> 0:07:47.960 which are coming from other devices. So that's where you 0:07:47.960 --> 0:07:52.000 get your your interference. If you're saying, what kind of 0:07:52.040 --> 0:07:55.200 interference could you possibly be talking about? While we're talking 0:07:55.240 --> 0:07:58.880 about things like your cordless phone in your house, for example, 0:07:59.080 --> 0:08:04.400 or perhaps an alarm system where you have uh wireless 0:08:04.760 --> 0:08:08.920 UM the devices that go above your windows and doors, 0:08:09.200 --> 0:08:12.320 if you know, it uses radio frequencies to talk to 0:08:12.360 --> 0:08:17.200 the main box UM and baby monitors stuff like that. 0:08:17.640 --> 0:08:20.920 Those are all using you know, those radio frequencies in 0:08:21.040 --> 0:08:24.080 those ranges. And of course you can you can buy 0:08:24.160 --> 0:08:28.240 cordless phones and and not to over use that word 0:08:28.560 --> 0:08:32.280 range of different frequencies. UM. So you could try to 0:08:32.280 --> 0:08:34.679 get to to get around that. But that's one of 0:08:34.720 --> 0:08:38.040 those things that I think they've been trying to improve 0:08:38.200 --> 0:08:40.160 is is cut down on some of the interference. And 0:08:40.200 --> 0:08:45.160 that's why um ATO two eleven A uses the orthogonal 0:08:45.200 --> 0:08:50.240 frequency division multiplexing. Basically, it's it's just a system of 0:08:50.280 --> 0:08:53.920 splitting down that signal into a group of sub signals 0:08:54.360 --> 0:08:57.480 to kind of make it less likely that you're going 0:08:57.520 --> 0:09:00.360 to be interfered with. It breaks it down so that 0:09:00.440 --> 0:09:03.280 it's not all in one one signal, Right, so you're 0:09:03.320 --> 0:09:06.240 not gonna you're not gonna have the same interference issues. 0:09:06.800 --> 0:09:10.000 UM it's you shouldn't. And again, like we point out, 0:09:10.000 --> 0:09:12.880 it is faster. ATO two point eleven A is faster 0:09:12.920 --> 0:09:15.440 than NATO to a point eleven B. But it's also 0:09:15.880 --> 0:09:19.400 it's UM range is shorter, it's not it doesn't go 0:09:19.480 --> 0:09:22.679 as far, and because of the frequencies that uses UM, 0:09:22.720 --> 0:09:26.400 it's a little more easily obstructed, So you can't necessarily 0:09:26.440 --> 0:09:29.520 broadcast through several walls. If you have a large house 0:09:29.520 --> 0:09:32.920 and you've got a wireless router in the middle, then 0:09:33.080 --> 0:09:35.920 you may notice that as you move away you start 0:09:35.960 --> 0:09:38.719 having problems getting a signal. I also suggested you don't 0:09:38.760 --> 0:09:43.080 make your walls out of lead. Yeah, I um, never again, 0:09:43.760 --> 0:09:46.400 never again. I tell you one thing. You know what, 0:09:46.760 --> 0:09:48.800 You make your walls out of lead, and you invite 0:09:48.840 --> 0:09:52.040 Superman over. The dude is just a total jerk face 0:09:52.600 --> 0:09:57.079 the entire time. He's just easy, right, He's just standing around, 0:09:57.120 --> 0:10:00.280 staring at the walls and just mumbling hers. I can't 0:10:00.280 --> 0:10:04.280 even repeat the things that man says. He just a 0:10:04.280 --> 0:10:07.120 lot of mouth on that guy. At any rate. I 0:10:07.679 --> 0:10:10.680 had no idea that my little joke would turn so awry. No, 0:10:10.840 --> 0:10:13.199 but tell you what, green Lantern is awesome. You get 0:10:13.200 --> 0:10:16.199 a few drinks in him, so uh so, yeah, eight 0:10:16.320 --> 0:10:19.880 two point eleven. A faster, shorter range also was more expensive. 0:10:20.400 --> 0:10:22.240 Both A and B were being worked on at the 0:10:22.240 --> 0:10:26.000 same time, UM B was. Even though B was slower, 0:10:26.320 --> 0:10:28.720 it was less expensive and had a greater range, so 0:10:28.800 --> 0:10:31.120 it it caught on a lot faster than A did. 0:10:31.679 --> 0:10:34.120 UM A was much more expensive, so you didn't really 0:10:34.160 --> 0:10:37.360 see that getting adopted in home networks as much. But 0:10:37.400 --> 0:10:41.319 that brings us up to eight to two point eleven G. Yes, 0:10:41.559 --> 0:10:45.720 we skipped a few letters and specifications, yes, UM not that. Yeah, 0:10:45.760 --> 0:10:47.520 I mean you could. If you look up all these 0:10:47.559 --> 0:10:51.960 different numbers UH along with I E, you'll see that 0:10:51.960 --> 0:10:54.400 there are all these different working groups that are working 0:10:54.440 --> 0:10:58.800 on various projects that have different designations. But it gets 0:10:58.800 --> 0:11:01.160 way too complex to talk about all that, especially since 0:11:01.160 --> 0:11:03.320 it doesn't really relate to what we're talking about here 0:11:03.360 --> 0:11:07.600 with home networking. So ATO two yeah, that was A 0:11:07.679 --> 0:11:10.719 and B were popular together for a while, and then 0:11:10.840 --> 0:11:14.880 G was a good sized leap forward. I would say, yeah, 0:11:15.000 --> 0:11:18.000 I agree, and it has been a standard. UM it's 0:11:18.000 --> 0:11:21.360 been widely adopted up until just recently, but we'll get 0:11:21.360 --> 0:11:23.640 into that in a moment. Um ATO two dot eleven 0:11:23.640 --> 0:11:27.559 G also uses the two point for giga hurts spectrum, 0:11:27.640 --> 0:11:30.920 just like ATO two dot eleven B. However, it is 0:11:31.000 --> 0:11:34.760 much faster band with up to fifty four megabits per 0:11:34.800 --> 0:11:37.640 second as I as I see before me, that's the 0:11:37.679 --> 0:11:39.520 figure I have. Yeah, that's the number I have as well. 0:11:39.640 --> 0:11:43.280 So yeah, that's really fast speed. And it's actually the 0:11:44.600 --> 0:11:48.199 it has really much better range. It's not easily obstructed, 0:11:48.240 --> 0:11:49.800 so it's it's kind of taking the best of both 0:11:49.800 --> 0:11:53.160 worlds here. It's got the range and and uh and 0:11:53.440 --> 0:11:56.560 the penetration of ATO two point eleven B and the 0:11:56.679 --> 0:12:01.400 speed and um and and uh well, probably just the 0:12:01.440 --> 0:12:06.000 speed of two point eleven eight UM. But it it 0:12:06.080 --> 0:12:08.200 was a little it's a little more expensive, or at 0:12:08.280 --> 0:12:10.480 least it was more expensive than NATO two point eleven B. 0:12:10.800 --> 0:12:13.640 It took a while for that too kind of become 0:12:13.679 --> 0:12:15.599 the standard and home networks, but that did become the 0:12:15.640 --> 0:12:20.679 standard after shortly after it was introduced, and uh so 0:12:20.760 --> 0:12:22.480 you would look on routers and you would see if 0:12:22.600 --> 0:12:26.040 we know which which standards it was compatible within eight 0:12:26.120 --> 0:12:29.360 or two point eleven G became more and more common 0:12:30.679 --> 0:12:35.080 and uh yeah, again had another problem with the fact 0:12:35.080 --> 0:12:39.040 that it had the unregulated signal, just like eight O 0:12:39.160 --> 0:12:42.480 two point eleven B did. So again there were there 0:12:42.600 --> 0:12:45.280 was at least the potential for signals to have some 0:12:45.360 --> 0:12:47.720 interference issues if you had a lot of other wireless 0:12:48.400 --> 0:12:51.040 technologies running in the house, a lot of kids running 0:12:51.040 --> 0:12:57.040 around on walkie talkies or you know exactly, I'll never 0:12:57.080 --> 0:13:00.840 be over it. I'm never over kids over at my 0:13:00.880 --> 0:13:03.440 house walking is that is just the most distracting thing 0:13:03.440 --> 0:13:05.280 in the world, because especially because you don't have kids. 0:13:05.360 --> 0:13:07.720 Yeah that who are you people? How did you get 0:13:07.720 --> 0:13:11.160 into my house? Did Superman let you in? Has he 0:13:11.280 --> 0:13:15.320 not gotten over the lead walls thing yet? You know? 0:13:15.520 --> 0:13:17.840 Does that bring us up to two eleven N Yes? 0:13:17.880 --> 0:13:20.880 And up until very very recently, this was not an 0:13:20.880 --> 0:13:25.280 approved standard. However, UM, you know I have seen from 0:13:25.320 --> 0:13:31.040 looking at the WiFi Alliances website, UM that at two 0:13:31.120 --> 0:13:36.240 dot eleven and is actually an accepted specification at this time, UM, 0:13:36.280 --> 0:13:38.560 which was supposed to happen this year. So you know 0:13:38.720 --> 0:13:40.880 that those of you who are going, you know, okay, 0:13:40.880 --> 0:13:42.880 so where's the surprise in that. No, that's that's uh, 0:13:42.960 --> 0:13:45.760 that's right on time. They're supposed to do that this year. UM. 0:13:46.160 --> 0:13:50.480 And uh, basically you're supposed to be able to get 0:13:50.520 --> 0:13:53.280 a lot better range with at two dot eleven N 0:13:54.440 --> 0:13:57.160 and speed for that matter, Um. That was one of 0:13:57.240 --> 0:14:00.120 the things when I got UM. I got a new 0:14:00.360 --> 0:14:05.040 wireless access point UM a few months ago, and it 0:14:05.120 --> 0:14:09.760 had a proposed ATO two dot eleven and specification in it. Um. 0:14:09.800 --> 0:14:12.160 You know, since I am sitting right next to or 0:14:12.200 --> 0:14:15.360 almost right next to the the access point, I find 0:14:15.360 --> 0:14:19.880 the ranges great. Yeah, but yeah, you are right next 0:14:19.920 --> 0:14:22.360 to it as if you could actually plug your device 0:14:22.480 --> 0:14:25.240 into it with a physical wire. How great the range 0:14:25.240 --> 0:14:28.720 of details details? Actually, Um, when I was down the hall, 0:14:28.760 --> 0:14:31.120 I actually moved the computer since then. UM, No, it 0:14:31.240 --> 0:14:33.200 was it was giving me a much better range than 0:14:33.240 --> 0:14:35.960 the old one. So UM, so you know it was 0:14:36.080 --> 0:14:39.840 it was an improvement. Um. But yeah, the ATO two 0:14:39.920 --> 0:14:42.120 dot eleven N is supposed to get you up to 0:14:42.160 --> 0:14:45.720 a hundred forty megabits per second, which is pretty speedy. 0:14:45.840 --> 0:14:49.920 Yeah that's considering I can't even get my my DSL 0:14:49.960 --> 0:14:55.920 connection near that fast. So you were asking Mark about 0:14:56.040 --> 0:14:59.640 the difficulties and networking. If you have different machines running 0:14:59.680 --> 0:15:03.320 on different uh that require different standards, Yes, that will 0:15:03.360 --> 0:15:06.320 be a problem because you have to have the right 0:15:06.600 --> 0:15:08.320 It's it's like an antenna. You have to the right 0:15:08.400 --> 0:15:10.640 kind of antenna to pick up the right kind of frequency. 0:15:10.800 --> 0:15:12.280 And UM, it sort of depends on what kind of 0:15:12.320 --> 0:15:15.000 card you have. Sorry interrupt, No, no no, go ahead, You 0:15:15.280 --> 0:15:18.720 need to have something that will receive these signals in 0:15:18.760 --> 0:15:23.560 your computer. UM and uh, you know, you can get 0:15:23.680 --> 0:15:26.040 cards that are built right in and there are also 0:15:26.360 --> 0:15:28.560 different kinds of cards that you can add on an 0:15:28.600 --> 0:15:32.000 aftermarket depending on what kind of computer you have. UM. 0:15:32.040 --> 0:15:34.000 And many of these cards can actually accept more than 0:15:34.040 --> 0:15:36.680 one standard, like they'll they'll say it'll be you know, 0:15:36.720 --> 0:15:38.840 you'll see like a B slash in or something like that, 0:15:38.960 --> 0:15:41.880 or in slash G or Yeah. The chances are actually 0:15:41.880 --> 0:15:43.880 if you go out and buy whatever off the shelf, 0:15:43.920 --> 0:15:46.920 now it's going to be end compatible and backwards compatible 0:15:46.960 --> 0:15:50.360 with the other three standards, which is great. I mean 0:15:50.440 --> 0:15:53.480 if you don't have those compatible ones, then obviously if 0:15:53.480 --> 0:15:55.080 you were to get if you were to have an 0:15:55.080 --> 0:15:59.040 old eight O two point eleven G wireless card and 0:15:59.040 --> 0:16:01.040 a laptop and you get an ETO two point eleven 0:16:01.360 --> 0:16:04.080 in router, it's not going to do any good. Yeah, 0:16:04.120 --> 0:16:05.760 you're not going to be able to access those faster 0:16:05.800 --> 0:16:09.440 speeds because you're limited by it's kind of the weakest 0:16:09.800 --> 0:16:12.200 link in the in the chain, kind of thing. Um, 0:16:12.240 --> 0:16:15.960 you're you're limited by whatever you are, Your least fast 0:16:16.400 --> 0:16:19.400 device is going to be uh in that in that 0:16:19.880 --> 0:16:23.520 chain from router to computer. So yeah, it can cause 0:16:23.520 --> 0:16:25.240 a little issue. It's not not as bad as you 0:16:25.320 --> 0:16:28.200 might think because most things that most have routers and 0:16:28.440 --> 0:16:31.280 modems that have been sold in the last few years 0:16:32.040 --> 0:16:33.720 have really kind of ironed out a lot of the 0:16:33.720 --> 0:16:38.800 compatibility issues. Um. But that's and you know, again, it's 0:16:38.880 --> 0:16:42.800 kind of confusing because the standards do evolve over time 0:16:42.840 --> 0:16:46.800 and the group is always working on different projects. That 0:16:47.040 --> 0:16:49.200 mean that you know, within another five or six years 0:16:49.240 --> 0:16:51.360 we may see something different. And not only that, but 0:16:51.440 --> 0:16:56.040 we have other networking technologies that also come into play 0:16:56.080 --> 0:16:59.400 that can be a little confusing. There's Bluetooth. Actually, it's 0:16:59.400 --> 0:17:01.600 funny you mentioned that. I was getting ready to mention. 0:17:02.000 --> 0:17:04.520 Please do um there are a couple different standards of 0:17:04.560 --> 0:17:09.080 Bluetooth technology now. Bluetooth UM in general has a shorter 0:17:10.040 --> 0:17:12.479 distance that you can use it a smaller range. Yes, 0:17:12.800 --> 0:17:17.840 that's what I meant. Thank you for fixing that. Um. Hey, 0:17:17.920 --> 0:17:19.960 who's the editor here? Yeah, well that would be me, 0:17:21.240 --> 0:17:24.600 except when I'm talking this is why I add it. Um. Yeah, 0:17:24.640 --> 0:17:28.160 it actually operates on frequency of two point four five 0:17:28.200 --> 0:17:32.240 gigga hurts uh generally between two point four zero two 0:17:32.240 --> 0:17:34.560 and two point four eight zero. If you're you know 0:17:34.640 --> 0:17:38.199 split in hair for those notes. Yeah, yeah, and you 0:17:38.240 --> 0:17:42.240 can you know, connect up to eight devices, um you 0:17:42.400 --> 0:17:44.920 find I don't think a lot of people use Bluetooth 0:17:44.920 --> 0:17:47.119 to connect a lot of devices to their computer. Maybe 0:17:47.160 --> 0:17:50.680 like a wireless keyboard, er mouse maybe maybe or or yeah, 0:17:50.720 --> 0:17:53.600 maybe a printer, sometimes your phone. I had a phone 0:17:53.600 --> 0:17:55.960 that used Bluetooth, and I could drag and drop files 0:17:55.960 --> 0:17:57.760 over like if I wanted to change ring tones, I 0:17:58.200 --> 0:18:01.399 make an MP three and and you know, connect with it. 0:18:01.520 --> 0:18:04.199 The promise of Bluetooth is really really cool in the 0:18:04.240 --> 0:18:08.600 sense that you can have this personal area network and 0:18:09.119 --> 0:18:12.159 you know, you the network would constantly be changing depending 0:18:12.200 --> 0:18:15.480 on what devices you brought within the scope of that network. 0:18:15.760 --> 0:18:18.000 So you can bring two devices together and it creates 0:18:18.000 --> 0:18:20.960 one network. You bring those two devices toward a third device, 0:18:21.000 --> 0:18:23.600 and you've got a new network. You take one device away. 0:18:23.920 --> 0:18:30.520 I mean, it's a really flexible, uh and and dynamic system. 0:18:30.560 --> 0:18:33.719 It's really really cool. I don't think anyone uses it 0:18:33.800 --> 0:18:37.600 to the to its potential. Really, I mean, I don't 0:18:37.760 --> 0:18:40.800 know one I know of uses Bluetooth. Like the people 0:18:40.840 --> 0:18:43.240 who use Bluetooth that I know are using the very 0:18:43.320 --> 0:18:46.639 very basic. So it's normally the headset and the and 0:18:46.760 --> 0:18:50.040 the phone the handset. Um, that's pretty much it. Or 0:18:50.320 --> 0:18:52.760 some of them are using some sort of handset and 0:18:52.880 --> 0:18:55.359 a car like the car that's Bluetooth enabled, so that 0:18:55.400 --> 0:18:57.520 the handset sinks with the car and they can listen 0:18:57.560 --> 0:19:01.160 to music, or they can use a EPs system something 0:19:01.200 --> 0:19:05.080 like that where or even use the cars sound system 0:19:05.119 --> 0:19:08.080 for a if they're taking on calls or things of 0:19:08.080 --> 0:19:11.080 that nature. But again it's still you're talking about a 0:19:11.080 --> 0:19:13.520 two device maximum there as opposed to what the real 0:19:13.560 --> 0:19:15.879 potential or Bluetooth is. I know somebody else is going 0:19:15.960 --> 0:19:18.119 to write into now that I think about it. Another 0:19:18.119 --> 0:19:21.280 device that you might see people use with their Bluetooth 0:19:21.359 --> 0:19:24.520 enabled computer and be a set of headphones. Yeah, that's 0:19:24.520 --> 0:19:28.480 that's pretty common. That's true. That's true. That's another common one. Um. 0:19:28.520 --> 0:19:33.320 And another thing we're another kind of wireless standard. Was 0:19:33.359 --> 0:19:36.159 going to talk about y max. So y max and 0:19:36.200 --> 0:19:39.720 WiFi are two different things. They are not the you 0:19:39.880 --> 0:19:42.920 often will see the media reference y max is saying 0:19:42.920 --> 0:19:47.120 something like WiFi on steroids, which is I mean it's 0:19:47.119 --> 0:19:50.840 an oversimplification. Yeah, it's definitely an oversimplification. Yes, y max 0:19:50.920 --> 0:19:54.840 has a greater range than WiFi standards because it can 0:19:54.840 --> 0:19:58.280 reach up to thirty miles right something like somewhere, and 0:19:58.280 --> 0:20:00.240 and so y max has a much larger ring change. 0:20:00.440 --> 0:20:04.320 And yes, you can get very fast uh down link 0:20:04.359 --> 0:20:06.840 and uplink speeds on y max are relatively fast in 0:20:06.920 --> 0:20:09.919 the way, about seventy megabits per seconds. So yeah, that's 0:20:09.960 --> 0:20:11.680 pretty fast. I mean it's still not as fast, you know, 0:20:11.760 --> 0:20:15.280 eight two point eleven and but yes, but you're not 0:20:15.320 --> 0:20:17.040 going to get an eight or two down eleven and 0:20:17.400 --> 0:20:19.480 much past oh I don't know, like the street in 0:20:19.520 --> 0:20:21.399 front of your house. Yeah, you're not gonna That's the 0:20:21.440 --> 0:20:23.640 other thing is that when we talk about these speeds, 0:20:23.680 --> 0:20:26.960 we're talking about the maximum that those devices are capable 0:20:27.000 --> 0:20:29.720 of generating. That doesn't necessarily mean that's the speed you 0:20:29.720 --> 0:20:32.920 will experience. I will experience it based upon what your 0:20:32.960 --> 0:20:35.879 I s P provides to you. Actually, when I was 0:20:35.880 --> 0:20:38.439 saying a few minutes ago that my DSL struggles to 0:20:38.480 --> 0:20:41.280 reach one point five megabits per second, you know, I 0:20:41.359 --> 0:20:43.640 have a my router now is an eight or two 0:20:43.600 --> 0:20:47.359 down eleven N I'm never gonna see anything faster than 0:20:47.440 --> 0:20:50.200 one point five megabits per second because that's as fast 0:20:50.200 --> 0:20:53.080 as it's gonna go. Now, if I connect with another computer, 0:20:53.960 --> 0:20:56.720 if I have, you know, say my music library on 0:20:56.760 --> 0:20:58.240 one computer I want to move it to another, I 0:20:58.240 --> 0:21:01.600 can move it at that speed provided my cards in 0:21:01.640 --> 0:21:04.560 both computers will reach that speed. So data transfers within 0:21:04.640 --> 0:21:08.120 your network will go at at the ideal speed, right, 0:21:08.359 --> 0:21:12.280 But data coming into or moving out of your network 0:21:12.400 --> 0:21:15.400 to the outside world the Internet is going to move 0:21:15.480 --> 0:21:19.200 at whatever speed the Internet service provider has designated or 0:21:19.400 --> 0:21:22.439 what your current technology is capable of delivering. Yeah, so 0:21:22.480 --> 0:21:24.800 the slowest point of connection in this case would be 0:21:24.840 --> 0:21:27.800 my you know, pipe to the outside world, and everything 0:21:27.840 --> 0:21:31.160 else is regulated by that, right, Everything inside super fast, 0:21:31.160 --> 0:21:35.000 everything outside not so fast. Still fast, just not nearly 0:21:35.040 --> 0:21:37.040 as fast as we sit there and think about how 0:21:37.040 --> 0:21:39.000 slow this is. But then we'd sit there and like, hey, 0:21:39.000 --> 0:21:43.440 do you remember that these bod modems. Okay, so it's 0:21:43.560 --> 0:21:45.920 very fast compared to dial up modems. So y max 0:21:45.920 --> 0:21:47.920 getting back to wy max um. Yeah, it's a totally 0:21:47.960 --> 0:21:51.720 different set of standards. Uh to dot one six. I 0:21:51.800 --> 0:21:53.879 like to I like to describe wy max the way 0:21:53.920 --> 0:21:56.920 I tried to describe it to someone, uh, and how 0:21:56.960 --> 0:21:58.480 it works if you if you want to try and 0:21:58.560 --> 0:22:02.720 visualize it within an analogy is imagine a big circular 0:22:03.040 --> 0:22:07.800 building that has a set number of doors along the 0:22:07.880 --> 0:22:10.880 perimeter of the building. So we'll say forty forty doors 0:22:10.920 --> 0:22:14.000 along the perimeter of the building. That means that forty 0:22:14.040 --> 0:22:16.880 people can walk in and out of that building, carrying 0:22:16.880 --> 0:22:19.320 stuff in and taking stuff out. So there's forty people 0:22:19.320 --> 0:22:21.520 that would be people connecting to the white Max tower 0:22:21.840 --> 0:22:27.040 to get data, so home networks necessary pretty much. Um 0:22:27.160 --> 0:22:30.480 and after the after those forty doors are taken up 0:22:30.520 --> 0:22:33.240 by the various people, that's it. It's not going to 0:22:33.280 --> 0:22:36.040 accept any more people on that tower, which means that 0:22:36.160 --> 0:22:39.640 every single person is going to still get the speeds 0:22:39.640 --> 0:22:43.040 that they were promised. You know, there's no choking because 0:22:43.080 --> 0:22:46.840 there's no bottleneck there because the tower has cut off 0:22:46.880 --> 0:22:49.520 the number of people who can connect to it. WiFi 0:22:49.600 --> 0:22:52.200 is different. WiFi people just keep piling in and out. 0:22:52.240 --> 0:22:54.960 There's like one big set of doors, and everyone is 0:22:54.960 --> 0:22:56.320 trying to get in and out of that set of 0:22:56.359 --> 0:22:59.040
