1
00:00:00,320 --> 00:00:02,880
Speaker 1: Brought to you by the reinvented two thousand twelve camera.

2
00:00:03,200 --> 00:00:08,920
Speaker 1: It's ready. Are you get in touch with technologies? With

3
00:00:09,080 --> 00:00:17,200
Speaker 1: tech stuff from how stuff works dot com. Hey, there

4
00:00:17,239 --> 00:00:19,479
Speaker 1: are kids, and welcome to tex stuff. My name is

5
00:00:19,520 --> 00:00:21,800
Speaker 1: Chris Pellette, and I'm an editor here at how stuff

6
00:00:21,800 --> 00:00:26,360
Speaker 1: works dot Com. Sitting across from me, as he always is,

7
00:00:26,360 --> 00:00:31,680
Speaker 1: is the smirking senior writer Jonathan Strickland. Hey there, you're

8
00:00:31,680 --> 00:00:35,120
Speaker 1: smirking at my opening my kids thing, right, Yeah, you

9
00:00:35,159 --> 00:00:37,360
Speaker 1: know I mix it up a little. It was I

10
00:00:37,440 --> 00:00:39,440
Speaker 1: never mix it up a little. That's well, you know,

11
00:00:39,520 --> 00:00:44,440
Speaker 1: it's good to humorless. That's true. That's true. Chris kill

12
00:00:44,560 --> 00:00:46,280
Speaker 1: Joy Pillette, that's what we call him here in the

13
00:00:46,280 --> 00:00:49,320
Speaker 1: office at how stuff works dot com. It's said, yeah,

14
00:00:49,520 --> 00:00:51,360
Speaker 1: I would find some humor in it, but I don't

15
00:00:51,400 --> 00:00:55,160
Speaker 1: never mind. Okay, it's better than Josh creepy hands Clark.

16
00:00:55,560 --> 00:00:58,720
Speaker 1: So you know, we all got our own little monikers.

17
00:00:59,320 --> 00:01:02,200
Speaker 1: I won't go into mind because you know, modesty forbids.

18
00:01:02,760 --> 00:01:06,160
Speaker 1: But let's start this off with a little listener mail.

19
00:01:09,480 --> 00:01:12,560
Speaker 1: This mail comes from Mark. Mark says, Dear tech Stuff,

20
00:01:12,600 --> 00:01:15,040
Speaker 1: thanks for a great podcast. I was wondering about how

21
00:01:15,040 --> 00:01:17,839
Speaker 1: wireless home networks work when my dad was talking about

22
00:01:17,920 --> 00:01:20,920
Speaker 1: upgrading ours and didn't know what the different network types were,

23
00:01:21,240 --> 00:01:24,759
Speaker 1: such as wireless G and wireless IN and how networking

24
00:01:24,800 --> 00:01:27,560
Speaker 1: you and not so new computers work and if it

25
00:01:27,600 --> 00:01:29,680
Speaker 1: will cause any problems. I think it would be an

26
00:01:29,680 --> 00:01:32,039
Speaker 1: interesting topic for a podcast because so many people have

27
00:01:32,160 --> 00:01:35,080
Speaker 1: home networks now. Anyway, thanks again for the great podcast

28
00:01:35,160 --> 00:01:38,560
Speaker 1: your seventh grade fan, Mark, well Mark. We thought we'd

29
00:01:38,560 --> 00:01:42,080
Speaker 1: talked a little bit about the different kinds of wireless

30
00:01:42,720 --> 00:01:45,400
Speaker 1: networks out there are the ones that use the various

31
00:01:45,520 --> 00:01:48,880
Speaker 1: standards set out by our good friends at the I

32
00:01:49,040 --> 00:01:56,440
Speaker 1: Triple E, or as I always like to call them I. Yeah. Yeah,

33
00:01:56,560 --> 00:02:01,120
Speaker 1: you know, early early networks were sort of like tin

34
00:02:01,240 --> 00:02:04,000
Speaker 1: cans with the string between them. This sort of makes

35
00:02:04,040 --> 00:02:07,240
Speaker 1: the string virtual. Yeah, there you go. That's all you

36
00:02:07,280 --> 00:02:14,560
Speaker 1: need to know. There's We're all right. So anyway, uh,

37
00:02:14,919 --> 00:02:17,760
Speaker 1: we're talking about a set of standards that in general

38
00:02:18,040 --> 00:02:22,200
Speaker 1: fall under the designation eight zero two point one one.

39
00:02:22,600 --> 00:02:25,760
Speaker 1: Doesn't that easy? Yeah, well it's it's the most those

40
00:02:25,800 --> 00:02:31,799
Speaker 1: are the most common frequency variations of wireless networking. So

41
00:02:33,240 --> 00:02:36,680
Speaker 1: the way you uh, you'll see on things like routers

42
00:02:36,680 --> 00:02:39,280
Speaker 1: and modems, and stuff. You'll see this number followed by

43
00:02:39,280 --> 00:02:42,639
Speaker 1: a letter, and that tells you which of the specific

44
00:02:42,720 --> 00:02:45,720
Speaker 1: sets of standards you're working with. Now you gotta understand

45
00:02:45,919 --> 00:02:48,960
Speaker 1: what I was getting Ready to correct myself because I

46
00:02:48,960 --> 00:02:53,600
Speaker 1: said frequency and that's not a frequency, it's just a designation.

47
00:02:53,720 --> 00:02:56,440
Speaker 1: Is a designation? Yes, so so the I triple E.

48
00:02:56,600 --> 00:03:03,320
Speaker 1: They they work on various designations for different UM networking solutions.

49
00:03:03,360 --> 00:03:05,440
Speaker 1: And with the eight to two point one one, you

50
00:03:05,480 --> 00:03:08,040
Speaker 1: have different working groups all working on different sets of

51
00:03:08,080 --> 00:03:13,560
Speaker 1: standards to try and create the most stable and reliable

52
00:03:14,000 --> 00:03:19,320
Speaker 1: form of wireless networking in this case wireless networking UM.

53
00:03:19,360 --> 00:03:21,640
Speaker 1: And it's it's a little confusing because you have all

54
00:03:21,639 --> 00:03:24,440
Speaker 1: these different groups working on working from the same basic

55
00:03:24,720 --> 00:03:27,760
Speaker 1: set of standards, but they're all tweaking them in different

56
00:03:27,760 --> 00:03:30,959
Speaker 1: ways to try and get different kinds of performance out

57
00:03:31,000 --> 00:03:34,560
Speaker 1: of them. So let's try and go through some of these.

58
00:03:34,600 --> 00:03:37,960
Speaker 1: It's really kind of complex, but um yeah. One of

59
00:03:38,000 --> 00:03:41,480
Speaker 1: the things to uh that's kind of interesting about these

60
00:03:41,560 --> 00:03:45,240
Speaker 1: different standards is, UH, as we start going through them,

61
00:03:45,280 --> 00:03:48,400
Speaker 1: if we are going through them in alphabetical order, you

62
00:03:48,440 --> 00:03:52,640
Speaker 1: will find that they do not necessarily uh go start

63
00:03:52,640 --> 00:03:55,480
Speaker 1: from the bottom up like if we start with eight

64
00:03:55,880 --> 00:03:59,960
Speaker 1: eight O two dot eleven A. Uh, this actually opera

65
00:04:00,040 --> 00:04:04,080
Speaker 1: rates on the five gigga hurts frequency and can carry

66
00:04:04,160 --> 00:04:08,200
Speaker 1: up to fifty four megabets of data per second. Uh.

67
00:04:08,320 --> 00:04:11,000
Speaker 1: In contrast ATO two dot eleven B you'd figured to

68
00:04:11,080 --> 00:04:14,560
Speaker 1: be faster. No, actually it's not. It operates at the

69
00:04:14,640 --> 00:04:18,000
Speaker 1: two point four gigga hurts frequency and only can handle

70
00:04:18,080 --> 00:04:21,640
Speaker 1: eleven megabets of data per second. And that's just one

71
00:04:21,680 --> 00:04:24,200
Speaker 1: of those things that makes it so confusing, is you

72
00:04:24,200 --> 00:04:26,280
Speaker 1: you'd figure there would be a logical progression there, and

73
00:04:26,320 --> 00:04:29,760
Speaker 1: there's not necessarily one. Yeah, so uh, what do you

74
00:04:29,760 --> 00:04:32,000
Speaker 1: think should we go by just by letter even though

75
00:04:32,040 --> 00:04:34,440
Speaker 1: it's not logical progression necessarily, but just to make it

76
00:04:34,480 --> 00:04:37,520
Speaker 1: easier to move from one to the other. Those two,

77
00:04:37,560 --> 00:04:39,839
Speaker 1: those two do fit well together because they were the

78
00:04:40,000 --> 00:04:46,560
Speaker 1: first two very common UM standards, at least in my experience. Well.

79
00:04:46,600 --> 00:04:52,360
Speaker 1: ATO two point eleven B uses uh unregulated radio signal

80
00:04:52,360 --> 00:04:57,760
Speaker 1: frequencies and the two point four gigga hurts range. So uh,

81
00:04:58,080 --> 00:05:00,080
Speaker 1: here's something. Here's some things about the ATO two A

82
00:05:00,160 --> 00:05:05,200
Speaker 1: point one one B set standards. It's single ranges is

83
00:05:05,240 --> 00:05:07,840
Speaker 1: pretty good UM. In the two point four gigg, it

84
00:05:07,920 --> 00:05:11,480
Speaker 1: hurts range, and it's not going to have problems with

85
00:05:11,520 --> 00:05:15,240
Speaker 1: obstructions that some other frequencies do. So in other words,

86
00:05:15,440 --> 00:05:18,120
Speaker 1: you might be able to use this kind of signal

87
00:05:18,240 --> 00:05:21,200
Speaker 1: through walls things like that. You don't have to worry

88
00:05:21,240 --> 00:05:24,240
Speaker 1: about losing signal as soon as you turn a corner

89
00:05:24,560 --> 00:05:29,320
Speaker 1: some UH from the source of the UH. The frequency UM,

90
00:05:29,360 --> 00:05:34,320
Speaker 1: and it's not very expensive. The range is pretty good, UM,

91
00:05:34,360 --> 00:05:37,520
Speaker 1: but it's not a very it's not very fast, as

92
00:05:37,520 --> 00:05:40,279
Speaker 1: you pointed out, you know, compared to eight oh two

93
00:05:40,320 --> 00:05:45,400
Speaker 1: point eleven A. It's it's fairly slow. UM. And because

94
00:05:45,440 --> 00:05:50,640
Speaker 1: it's an unregulated frequency, some other appliances that generate radio

95
00:05:50,680 --> 00:05:56,440
Speaker 1: frequencies can cause interference within that wireless UH frequency because

96
00:05:56,480 --> 00:06:00,599
Speaker 1: you have to remember the computer you're using whatever, Like

97
00:06:00,640 --> 00:06:04,400
Speaker 1: if you have a wireless router that's broadcasting WiFi on

98
00:06:04,960 --> 00:06:09,280
Speaker 1: this set of standards, if it's using unregulated radio frequencies,

99
00:06:09,279 --> 00:06:11,919
Speaker 1: that means that it can fall within a wider range,

100
00:06:12,360 --> 00:06:16,000
Speaker 1: and that things that also generate radio frequencies within that range.

101
00:06:16,200 --> 00:06:18,400
Speaker 1: When you're using your computer, your computer doesn't know which

102
00:06:18,400 --> 00:06:20,400
Speaker 1: one of those which of those signals are coming from

103
00:06:20,400 --> 00:06:23,680
Speaker 1: your router and which are coming from other devices. So

104
00:06:23,760 --> 00:06:26,800
Speaker 1: that's where you get your your interference. And if you're

105
00:06:26,839 --> 00:06:31,039
Speaker 1: saying what kind of interference could you possibly be talking about, Well,

106
00:06:31,080 --> 00:06:34,080
Speaker 1: we're talking about things like your cordless phone in your

107
00:06:34,080 --> 00:06:38,320
Speaker 1: house for example, or UM perhaps an alarm system where

108
00:06:38,360 --> 00:06:44,039
Speaker 1: you have UH wireless UM the devices that go above

109
00:06:44,080 --> 00:06:46,920
Speaker 1: your windows and doors, if it you know it uses

110
00:06:47,000 --> 00:06:50,800
Speaker 1: radio frequencies to talk to the main box, UM and

111
00:06:51,160 --> 00:06:55,479
Speaker 1: baby monitors stuff like that. Those are all using you know,

112
00:06:55,520 --> 00:06:59,720
Speaker 1: those radio frequencies in those ranges. And of course you

113
00:06:59,760 --> 00:07:03,440
Speaker 1: can you can buy cordless phones and are not to

114
00:07:03,720 --> 00:07:07,920
Speaker 1: over use that word range of different frequencies UM. So

115
00:07:07,960 --> 00:07:09,840
Speaker 1: you could try to get to to get around that.

116
00:07:09,880 --> 00:07:12,880
Speaker 1: But UM that's one of those things that UH I

117
00:07:12,920 --> 00:07:15,360
Speaker 1: think they've been trying to improve is is cut down

118
00:07:15,360 --> 00:07:18,040
Speaker 1: on some of the interference. And that's why um ATO

119
00:07:18,120 --> 00:07:24,120
Speaker 1: two eleven A uses the orthogonal frequency division multiplexing. Basically,

120
00:07:24,160 --> 00:07:27,760
Speaker 1: it's it's just a system of splitting down that signal

121
00:07:27,800 --> 00:07:31,240
Speaker 1: into a group of sub signals to kind of make

122
00:07:31,280 --> 00:07:34,880
Speaker 1: it UH less likely that you're going to be interfered with,

123
00:07:34,960 --> 00:07:37,440
Speaker 1: and breaks it down so that it's not all in

124
00:07:37,440 --> 00:07:39,960
Speaker 1: in one UH one signal right, so you're not gonna

125
00:07:40,120 --> 00:07:44,120
Speaker 1: you're not gonna have the same interference issues. UM, it's

126
00:07:44,160 --> 00:07:46,520
Speaker 1: you shouldn't. And again, like we point out, it is

127
00:07:46,600 --> 00:07:49,560
Speaker 1: faster at two point eleven A is faster than NATO

128
00:07:49,560 --> 00:07:53,160
Speaker 1: to a point eleven B. But it's also it's UM

129
00:07:53,440 --> 00:07:56,080
Speaker 1: range is shorter, it's not it doesn't go as far.

130
00:07:56,240 --> 00:07:59,200
Speaker 1: And because of the frequencies that uses UM, it's a

131
00:07:59,280 --> 00:08:03,640
Speaker 1: little more easily obstructed. So you can't necessarily broadcast through

132
00:08:03,840 --> 00:08:06,080
Speaker 1: several walls. If you have a large house and you've

133
00:08:06,080 --> 00:08:09,680
Speaker 1: got a wireless router in the middle, then you may

134
00:08:09,800 --> 00:08:12,760
Speaker 1: notice that as you move away you start having problems

135
00:08:12,760 --> 00:08:15,120
Speaker 1: getting a signal. I also suggest that you don't make

136
00:08:15,160 --> 00:08:19,320
Speaker 1: your walls out of lead. Yeah, I um, never again,

137
00:08:20,040 --> 00:08:22,680
Speaker 1: never again. I tell you one thing. You know what,

138
00:08:23,040 --> 00:08:25,080
Speaker 1: You make your walls out of lead, and you invite

139
00:08:25,120 --> 00:08:28,320
Speaker 1: Superman over. The dude is just a total jerk face

140
00:08:28,840 --> 00:08:32,680
Speaker 1: the entire time. Well he's just hes right, he's just

141
00:08:32,720 --> 00:08:35,960
Speaker 1: standing around, staring at the walls and just mumbling curses.

142
00:08:36,080 --> 00:08:39,720
Speaker 1: I can't even repeat the things that man says. He

143
00:08:39,960 --> 00:08:43,280
Speaker 1: just Oh what a mouth on that guy. At any rate,

144
00:08:43,360 --> 00:08:45,840
Speaker 1: I had no idea that my little joke would turn

145
00:08:46,000 --> 00:08:49,160
Speaker 1: so awry. No, but tell you what, green lantern is awesome.

146
00:08:49,200 --> 00:08:51,880
Speaker 1: You get a few drinks in him. So uh so

147
00:08:52,000 --> 00:08:54,839
Speaker 1: yeah eight to two point eleven A faster, shorter range,

148
00:08:54,960 --> 00:08:57,880
Speaker 1: also was more expensive. Both A and B were being

149
00:08:57,920 --> 00:09:01,079
Speaker 1: worked on at the same time. UM B was even

150
00:09:01,120 --> 00:09:04,000
Speaker 1: though B was slower, it was less expensive and had

151
00:09:04,040 --> 00:09:06,280
Speaker 1: a greater range, so it it caught on a lot

152
00:09:06,320 --> 00:09:09,560
Speaker 1: faster than A did. Um A was much more expensive,

153
00:09:09,600 --> 00:09:11,920
Speaker 1: so you didn't really see that getting adopted in home

154
00:09:12,000 --> 00:09:14,959
Speaker 1: networks as much. But that brings us up to ATO

155
00:09:15,040 --> 00:09:19,000
Speaker 1: two point eleven. G. Yes, we skipped a few letters

156
00:09:19,000 --> 00:09:22,600
Speaker 1: and specifications, yes, um not that. Yeah, I mean you could.

157
00:09:22,679 --> 00:09:25,920
Speaker 1: If you look up all these different numbers, uh along

158
00:09:26,240 --> 00:09:28,800
Speaker 1: with I E. You'll see that there are all these

159
00:09:28,800 --> 00:09:31,800
Speaker 1: different working groups that are working on various projects that

160
00:09:31,920 --> 00:09:36,000
Speaker 1: have different designations. But it gets way too complex to

161
00:09:36,040 --> 00:09:38,400
Speaker 1: talk about all that, especially since it doesn't really relate

162
00:09:38,400 --> 00:09:41,280
Speaker 1: to what we're talking about here with home networking. So

163
00:09:41,320 --> 00:09:44,120
Speaker 1: ATO two point eleven. Yeah, that was A and B

164
00:09:44,240 --> 00:09:47,600
Speaker 1: were popular together for a while, and then G was

165
00:09:48,480 --> 00:09:51,720
Speaker 1: a good sized leap forward. I would say, yeah, I agree,

166
00:09:51,800 --> 00:09:54,800
Speaker 1: and it has been the standard. Um it's been widely

167
00:09:54,800 --> 00:09:57,960
Speaker 1: adopted up until just recently, but we'll get into that

168
00:09:58,000 --> 00:10:00,480
Speaker 1: in a moment. Um ATO two dot eleven G also

169
00:10:00,559 --> 00:10:04,079
Speaker 1: uses the two point for giga hurts spectrum, just like

170
00:10:04,240 --> 00:10:07,840
Speaker 1: at two dot eleven B. However, it is much faster

171
00:10:08,520 --> 00:10:11,480
Speaker 1: band with up to fifty four megabits per second as

172
00:10:11,520 --> 00:10:14,320
Speaker 1: I as I see before me, that's the figure I

173
00:10:14,360 --> 00:10:18,440
Speaker 1: have as well. So yeah, that's really fast speed. And

174
00:10:18,480 --> 00:10:23,280
Speaker 1: it's actually the it has really much better range. It's

175
00:10:23,320 --> 00:10:25,480
Speaker 1: not easily obstructed, so it's it's kind of taking the

176
00:10:25,559 --> 00:10:28,480
Speaker 1: best of both worlds here. It's got the range and

177
00:10:28,480 --> 00:10:32,200
Speaker 1: and uh and the penetration of ATO two point eleven

178
00:10:32,200 --> 00:10:36,960
Speaker 1: B and the speed and um and and uh well

179
00:10:37,120 --> 00:10:40,480
Speaker 1: probably just the speed of two point eleven A UM.

180
00:10:40,640 --> 00:10:44,079
Speaker 1: But it it was a little it's a little more expensive,

181
00:10:44,320 --> 00:10:46,120
Speaker 1: or at least it was more expensive than ATO two

182
00:10:46,160 --> 00:10:48,599
Speaker 1: point eleven B. It took a while for that to

183
00:10:49,360 --> 00:10:51,320
Speaker 1: kind of become the standard and home networks, but that

184
00:10:51,360 --> 00:10:54,520
Speaker 1: did become the standard after shortly after it was introduced.

185
00:10:55,559 --> 00:10:58,199
Speaker 1: And uh so you would look on routers and you

186
00:10:58,200 --> 00:11:00,520
Speaker 1: would see if we know which which, then it was

187
00:11:01,240 --> 00:11:04,640
Speaker 1: compatible within eight or two point eleven G became more

188
00:11:04,679 --> 00:11:10,840
Speaker 1: and more common and uh yeah, again had another problem

189
00:11:10,840 --> 00:11:14,280
Speaker 1: with the fact that it had the unregulated signal, just

190
00:11:14,360 --> 00:11:18,240
Speaker 1: like a two point eleven B did. So again there

191
00:11:18,240 --> 00:11:20,960
Speaker 1: were there was at least the potential for signals to

192
00:11:21,160 --> 00:11:23,199
Speaker 1: have some interference issues if you had a lot of

193
00:11:23,240 --> 00:11:26,599
Speaker 1: other wireless technologies running in the house, a lot of

194
00:11:26,679 --> 00:11:32,000
Speaker 1: kids running around on walkie talkies or you know exactly,

195
00:11:32,880 --> 00:11:36,800
Speaker 1: I'll never be over it. I'm never over kids over

196
00:11:36,840 --> 00:11:39,120
Speaker 1: at my house walkie talkies. That is just the most

197
00:11:39,120 --> 00:11:41,200
Speaker 1: distracting thing in the world, because especially because you don't

198
00:11:41,200 --> 00:11:44,240
Speaker 1: have kids. Yeah that people, how did you get into

199
00:11:44,240 --> 00:11:47,640
Speaker 1: my house? Did Superman let you in? Has he not

200
00:11:47,800 --> 00:11:52,240
Speaker 1: gotten over the lead walls thing? Yet? Does that bring

201
00:11:52,280 --> 00:11:54,920
Speaker 1: us up to two eleven in? Yes? And up until

202
00:11:55,520 --> 00:11:58,480
Speaker 1: very very recently, this was not an approved standard. However,

203
00:11:59,400 --> 00:12:03,080
Speaker 1: UM know I have seen from looking at the WiFi

204
00:12:03,080 --> 00:12:08,640
Speaker 1: Alliance's website, UM that ATO two dot eleven and is

205
00:12:08,760 --> 00:12:12,920
Speaker 1: actually an accepted specification at this time, um, which was

206
00:12:12,920 --> 00:12:15,920
Speaker 1: supposed to happen this year. So you know that those

207
00:12:15,960 --> 00:12:17,559
Speaker 1: of you who are going, yeah, okay, so where's the

208
00:12:17,600 --> 00:12:19,880
Speaker 1: surprise in that. No, that's that's uh, that's right on time.

209
00:12:19,920 --> 00:12:23,960
Speaker 1: They're supposed to do that this year. Um. And UH,

210
00:12:24,000 --> 00:12:27,200
Speaker 1: basically you're supposed to be able to get a lot

211
00:12:27,280 --> 00:12:31,280
Speaker 1: better range with ATO two dot eleven and and speed

212
00:12:31,320 --> 00:12:33,800
Speaker 1: for that matter. UM, that was one of the things

213
00:12:33,880 --> 00:12:38,320
Speaker 1: when I got UM. I got a new wireless access

214
00:12:38,360 --> 00:12:42,040
Speaker 1: point UM a few months ago, and it had a

215
00:12:42,240 --> 00:12:45,920
Speaker 1: proposed ATO two dot eleven and specification in it. Um.

216
00:12:46,080 --> 00:12:48,439
Speaker 1: You know, since I am sitting right next to or

217
00:12:48,480 --> 00:12:51,640
Speaker 1: almost right next to the the access point, I find

218
00:12:51,640 --> 00:12:56,160
Speaker 1: the range is great. But yeah, you are right next

219
00:12:56,200 --> 00:12:58,640
Speaker 1: to it as if you could actually plug your device

220
00:12:58,760 --> 00:13:01,520
Speaker 1: into it with a physical are how great the range

221
00:13:01,520 --> 00:13:04,960
Speaker 1: of details details? Actually? Um, when I was down the hall,

222
00:13:05,040 --> 00:13:07,400
Speaker 1: I actually moved the computer since then, UM no, it

223
00:13:07,480 --> 00:13:09,480
Speaker 1: was it was giving me a much better range than

224
00:13:09,480 --> 00:13:12,200
Speaker 1: the old one, so UM, so you know it was

225
00:13:12,360 --> 00:13:15,599
Speaker 1: it was an improvement. Um. But yeah, the eight to

226
00:13:15,760 --> 00:13:18,320
Speaker 1: two dot eleven N is supposed to get you up

227
00:13:18,320 --> 00:13:22,360
Speaker 1: to a hundred forty megabits per second, which is pretty speedy. Yeah,

228
00:13:22,480 --> 00:13:26,640
Speaker 1: that's considering I can't even get my my DSL connection

229
00:13:26,880 --> 00:13:32,440
Speaker 1: near that fast. So you were asking Mark about the

230
00:13:32,480 --> 00:13:36,080
Speaker 1: difficulties in networking if you have different machines running on

231
00:13:36,240 --> 00:13:39,800
Speaker 1: different uh that require different standards. Yes, that will be

232
00:13:39,880 --> 00:13:43,040
Speaker 1: a problem because you have to have the right it's

233
00:13:43,120 --> 00:13:44,760
Speaker 1: it's like an antenna. You have to the right kind

234
00:13:44,800 --> 00:13:46,920
Speaker 1: of antend to pick up the right kind of frequency.

235
00:13:47,000 --> 00:13:48,560
Speaker 1: And um, it sort of depends on what kind of

236
00:13:48,600 --> 00:13:51,480
Speaker 1: card you have sorright interrupt No, no, go ahead. You

237
00:13:51,520 --> 00:13:55,000
Speaker 1: need to have something that will receive the signals in

238
00:13:55,040 --> 00:13:59,840
Speaker 1: your computer. Um. And uh, you know you can get

239
00:14:00,000 --> 00:14:02,280
Speaker 1: cards that are built right in. And there are also

240
00:14:02,600 --> 00:14:04,839
Speaker 1: different kinds of cards that you can add on an

241
00:14:04,840 --> 00:14:08,280
Speaker 1: aftermarket depending on what kind of computer you have. UM.

242
00:14:08,320 --> 00:14:10,280
Speaker 1: And many of these cards can actually accept more than

243
00:14:10,320 --> 00:14:12,920
Speaker 1: one standard, like they'll they'll say it'll be you know,

244
00:14:12,960 --> 00:14:15,120
Speaker 1: you'll see like a B slash in or something like that,

245
00:14:15,200 --> 00:14:18,160
Speaker 1: or in slash G or Yeah. The chances are actually

246
00:14:18,160 --> 00:14:20,160
Speaker 1: if you go out and buy whatever off the shelf,

247
00:14:20,200 --> 00:14:23,200
Speaker 1: now it's going to be end compatible and backwards compatible

248
00:14:23,200 --> 00:14:26,680
Speaker 1: with the other three standards, which is great. I mean

249
00:14:26,680 --> 00:14:29,720
Speaker 1: if you don't have those compatible ones, then obviously if

250
00:14:29,720 --> 00:14:31,360
Speaker 1: you were to get if you were to have an

251
00:14:31,360 --> 00:14:35,360
Speaker 1: old ATO two point eleven G wireless card and a

252
00:14:35,440 --> 00:14:38,480
Speaker 1: laptop and you got an ATO two point eleven in router,

253
00:14:39,000 --> 00:14:40,840
Speaker 1: it's not gonna do any good. Yeah, you're not gonna

254
00:14:40,880 --> 00:14:43,840
Speaker 1: be able to access those faster speeds because you're limited

255
00:14:43,880 --> 00:14:46,800
Speaker 1: by it's kind of the weakest link in the in

256
00:14:46,840 --> 00:14:49,480
Speaker 1: the chain kind of thing. Um, you're you're limited by

257
00:14:49,520 --> 00:14:53,480
Speaker 1: whatever you are, your least fast device is going to

258
00:14:53,600 --> 00:14:57,680
Speaker 1: be uh in that in that chain from router to computer.

259
00:14:58,240 --> 00:15:00,840
Speaker 1: So yeah, it can cause a little issue. It's not

260
00:15:00,840 --> 00:15:03,160
Speaker 1: not as bad as you might think because most things

261
00:15:03,160 --> 00:15:05,560
Speaker 1: that are most of routers and modems that have been

262
00:15:05,600 --> 00:15:09,240
Speaker 1: sold in the last few years have really kind of

263
00:15:09,280 --> 00:15:13,200
Speaker 1: ironed out a lot of the compatibility issues. Um. But

264
00:15:13,320 --> 00:15:16,200
Speaker 1: that's and you know, again it's kind of confusing because

265
00:15:16,280 --> 00:15:20,800
Speaker 1: the standards do evolve over time and the group is

266
00:15:20,840 --> 00:15:24,000
Speaker 1: always working on different projects. That mean that you know,

267
00:15:24,080 --> 00:15:26,600
Speaker 1: within another five or six years we may see something different.

268
00:15:26,880 --> 00:15:30,240
Speaker 1: And not only that, but we have other networking technologies

269
00:15:30,280 --> 00:15:33,920
Speaker 1: that also come into play that can be a little confusing.

270
00:15:33,960 --> 00:15:36,880
Speaker 1: There's Bluetooth. Actually, it's funny you mentioned that I was

271
00:15:36,920 --> 00:15:39,800
Speaker 1: getting ready to mention please do um. There are a

272
00:15:39,800 --> 00:15:43,520
Speaker 1: couple different standards of Bluetooth technology. Now. Bluetooth UM in

273
00:15:43,600 --> 00:15:47,760
Speaker 1: general has a shorter distance that you can use a

274
00:15:47,840 --> 00:15:51,200
Speaker 1: smaller range. Yes, that's what I meant thank you for

275
00:15:51,240 --> 00:15:55,680
Speaker 1: fixing that. Um hey, who's the editor here? Yeah, well

276
00:15:55,720 --> 00:15:58,800
Speaker 1: that would be me, except when I'm talking. This is

277
00:15:58,840 --> 00:16:03,360
Speaker 1: why I edit. Um. Yeah. It actually operates on frequency

278
00:16:03,360 --> 00:16:06,960
Speaker 1: of two point four five giga hurts. Uh, generally between

279
00:16:06,960 --> 00:16:09,640
Speaker 1: two point four zero two and two point four eight

280
00:16:09,720 --> 00:16:12,120
Speaker 1: zero if you're you know split in hair for those

281
00:16:12,120 --> 00:16:14,880
Speaker 1: of you taking notes, Yeah, yeah, and you can you know,

282
00:16:14,920 --> 00:16:19,480
Speaker 1: connect up to eight devices. Um you find I don't

283
00:16:19,520 --> 00:16:21,680
Speaker 1: think a lot of people use Bluetooth to connect a

284
00:16:21,680 --> 00:16:23,600
Speaker 1: lot of devices to their computer. Exp maybe like a

285
00:16:23,600 --> 00:16:27,600
Speaker 1: wireless keyboarder mouse maybe maybe or or yeah, maybe a printer,

286
00:16:28,040 --> 00:16:30,880
Speaker 1: sometimes your phone. I had a phone that used Bluetooth,

287
00:16:30,880 --> 00:16:32,600
Speaker 1: and I could drag and drop files over like if

288
00:16:32,640 --> 00:16:35,000
Speaker 1: I wanted to change ring tones, I make an MP

289
00:16:35,120 --> 00:16:37,800
Speaker 1: three and and you know, connect with it. The wireless

290
00:16:37,800 --> 00:16:40,480
Speaker 1: The promise of Bluetooth is really really cool in the

291
00:16:40,520 --> 00:16:44,880
Speaker 1: sense that you can have this personal area network and

292
00:16:45,360 --> 00:16:48,440
Speaker 1: you know, you the network would constantly be changing depending

293
00:16:48,480 --> 00:16:51,760
Speaker 1: on what devices you brought within the scope of that network.

294
00:16:52,000 --> 00:16:54,840
Speaker 1: So you can bring two devices together, it creates one network.

295
00:16:55,080 --> 00:16:57,360
Speaker 1: You bring those two devices toward a third device, and

296
00:16:57,360 --> 00:16:59,840
Speaker 1: you've got a new network. You take one device away.

297
00:17:00,200 --> 00:17:06,800
Speaker 1: I mean it's a really flexible UM and and dynamic system.

298
00:17:06,840 --> 00:17:10,000
Speaker 1: It's really really cool. I don't think anyone uses it

299
00:17:10,040 --> 00:17:13,840
Speaker 1: to the to its potential really. I mean, I don't

300
00:17:14,000 --> 00:17:17,080
Speaker 1: know one I know of uses Bluetooth. Like the people

301
00:17:17,119 --> 00:17:19,520
Speaker 1: who use Bluetooth that I know are using the very

302
00:17:19,600 --> 00:17:23,080
Speaker 1: very basic. So it's the headset and the and the

303
00:17:23,160 --> 00:17:26,720
Speaker 1: phone the handset. Um that's pretty much it. Or some

304
00:17:26,840 --> 00:17:29,280
Speaker 1: of them are using some sort of handset and a

305
00:17:29,280 --> 00:17:31,760
Speaker 1: car like the car that's Bluetooth enabled so that the

306
00:17:31,800 --> 00:17:34,320
Speaker 1: handset sinks with the car and they can listen to music,

307
00:17:34,760 --> 00:17:37,760
Speaker 1: or they can use a GPS system something like that

308
00:17:38,320 --> 00:17:41,679
Speaker 1: where or even use the cars sound system for a

309
00:17:42,640 --> 00:17:44,840
Speaker 1: if they're taking on calls or things of that nature.

310
00:17:45,280 --> 00:17:47,919
Speaker 1: But again it's still you're talking about a two device

311
00:17:48,000 --> 00:17:50,359
Speaker 1: maximum there as opposed to what the real potential or

312
00:17:50,359 --> 00:17:52,480
Speaker 1: Bluetooth is. I know somebody else is going to write

313
00:17:52,520 --> 00:17:54,840
Speaker 1: into now that I think about it. Another device that

314
00:17:54,920 --> 00:17:58,359
Speaker 1: you might see people use with their Bluetooth enabled computer

315
00:17:58,400 --> 00:18:01,480
Speaker 1: and be a set of headphones. Yeah, that's that's pretty common.

316
00:18:01,480 --> 00:18:04,720
Speaker 1: That's true. That's true. That is another common one. Um

317
00:18:04,760 --> 00:18:09,600
Speaker 1: and another thing we're another kind of wireless standard. Was

318
00:18:09,640 --> 00:18:12,399
Speaker 1: going to talk about y max. So y max and

319
00:18:12,440 --> 00:18:16,000
Speaker 1: WiFi are two different things. They are not the You

320
00:18:16,119 --> 00:18:19,200
Speaker 1: often will see the media reference why max is saying

321
00:18:19,200 --> 00:18:23,360
Speaker 1: something like WiFi on steroids, which is I mean it's

322
00:18:23,400 --> 00:18:27,119
Speaker 1: an oversimplification. Yeah, it's definitely an oversimplification. Yes, y max

323
00:18:27,200 --> 00:18:31,120
Speaker 1: has a greater range than WiFi standards because it can

324
00:18:31,119 --> 00:18:33,760
Speaker 1: reach up to a thirty miles right, something like somewhere.

325
00:18:33,760 --> 00:18:37,160
Speaker 1: And so wy max has a much larger range. And yes,

326
00:18:37,240 --> 00:18:41,119
Speaker 1: you can get very fast. Uh, down link and uplink

327
00:18:41,160 --> 00:18:44,720
Speaker 1: speeds on y max are relatively fast anyway, about megabits

328
00:18:44,720 --> 00:18:47,040
Speaker 1: per seconds. So yeah, that's pretty fast. I mean it's

329
00:18:47,040 --> 00:18:48,439
Speaker 1: still not as fast as you know, eight or two

330
00:18:48,480 --> 00:18:51,959
Speaker 1: point eleven and but yes, but you're not gonna get

331
00:18:52,040 --> 00:18:54,840
Speaker 1: eight or two down eleven and much past I don't know,

332
00:18:55,080 --> 00:18:56,800
Speaker 1: like the street in front of your house. Yeah, you're

333
00:18:56,800 --> 00:18:58,760
Speaker 1: not gonna That's the other thing is that when we

334
00:18:58,800 --> 00:19:01,800
Speaker 1: talk about these speeds, we're talking about the maximum that

335
00:19:01,840 --> 00:19:05,280
Speaker 1: those devices are capable of generating. That doesn't necessarily mean

336
00:19:05,280 --> 00:19:07,600
Speaker 1: that's the speed you will experience. That will experience it

337
00:19:08,040 --> 00:19:10,760
Speaker 1: based upon what your I s P provides to you.

338
00:19:11,560 --> 00:19:13,040
Speaker 1: Actually when I was saying a few minutes ago that

339
00:19:13,160 --> 00:19:16,840
Speaker 1: my DSL struggles to reach one point five megabet per second.

340
00:19:17,240 --> 00:19:19,480
Speaker 1: You know, I have a my router now is an

341
00:19:19,480 --> 00:19:21,879
Speaker 1: eight or two data eleven n I'm never gonna see

342
00:19:22,400 --> 00:19:25,639
Speaker 1: anything faster than one point five megabets per second, because

343
00:19:25,680 --> 00:19:27,800
Speaker 1: that's as fast as it's gonna go out. Now, if

344
00:19:27,840 --> 00:19:32,000
Speaker 1: I connect with another computer, if I have, you know, say,

345
00:19:32,080 --> 00:19:33,960
Speaker 1: my music library at one computer I want to move

346
00:19:33,960 --> 00:19:35,600
Speaker 1: it to another, I can move it at that speed

347
00:19:36,400 --> 00:19:39,600
Speaker 1: provided my cards in both computers will reach that speed.

348
00:19:39,640 --> 00:19:42,360
Speaker 1: So data transfers within your network will go at at

349
00:19:42,400 --> 00:19:46,879
Speaker 1: the ideal speed, right, But data coming into or moving

350
00:19:46,880 --> 00:19:50,840
Speaker 1: out of your network to the outside world the Internet,

351
00:19:51,160 --> 00:19:53,280
Speaker 1: is going to move at whatever speed the Internet service

352
00:19:53,320 --> 00:19:57,719
Speaker 1: provider has designated, or what your current technology is capable

353
00:19:57,760 --> 00:20:00,280
Speaker 1: of delivering. Yeah, so the slowest point of connect in

354
00:20:00,280 --> 00:20:02,320
Speaker 1: this case would be my you know, pipe to the

355
00:20:02,359 --> 00:20:05,560
Speaker 1: outside world, and everything else is regulated by that, right,

356
00:20:05,680 --> 00:20:10,159
Speaker 1: Everything inside super fast, everything outside not so fast. Still fast,

357
00:20:10,359 --> 00:20:12,760
Speaker 1: just not nearly as fast. As we sit there and

358
00:20:12,800 --> 00:20:14,560
Speaker 1: think about how slow this is. But then we sit

359
00:20:14,600 --> 00:20:19,440
Speaker 1: there and like, hey, do you remember that there's bod modems? Okay,

360
00:20:19,480 --> 00:20:22,040
Speaker 1: so it's very fast compared to dial up modems. But anyway,

361
00:20:22,119 --> 00:20:24,600
Speaker 1: so so wy max getting back to wymax. Um, yeah,

362
00:20:24,600 --> 00:20:28,600
Speaker 1: it's a totally different set of standards. Uh, dot one six.

363
00:20:28,720 --> 00:20:30,800
Speaker 1: I like to I like to describe wy max the

364
00:20:30,840 --> 00:20:33,560
Speaker 1: way I tried to describe it to someone, uh, and

365
00:20:33,760 --> 00:20:35,479
Speaker 1: how it works if you if you want to try

366
00:20:35,520 --> 00:20:39,040
Speaker 1: and visualize it within an analogy is imagine a big

367
00:20:39,119 --> 00:20:44,560
Speaker 1: circular building that has a set number of doors along

368
00:20:44,600 --> 00:20:47,639
Speaker 1: the perimeter of the building. So we'll say forty forty

369
00:20:47,720 --> 00:20:50,240
Speaker 1: doors are along the perimeter of the building. That means

370
00:20:50,280 --> 00:20:53,280
Speaker 1: that forty people can walk in and out of that building,

371
00:20:53,600 --> 00:20:56,119
Speaker 1: carrying stuff in and taking stuff out. So there's forty

372
00:20:56,119 --> 00:20:58,280
Speaker 1: people that would be people connecting to the y max

373
00:20:58,320 --> 00:21:04,120
Speaker 1: tower to get data. So home networks necessary pretty much. Um.

374
00:21:04,240 --> 00:21:07,600
Speaker 1: And after the after those forty doors are taken up

375
00:21:07,600 --> 00:21:10,320
Speaker 1: by the various people, that's it. It's not going to

376
00:21:10,359 --> 00:21:13,119
Speaker 1: accept any more people on that tower, which means that

377
00:21:13,240 --> 00:21:16,720
Speaker 1: every single person is going to still get the speeds

378
00:21:16,720 --> 00:21:20,119
Speaker 1: that they were promised. You know, there's no choking because

379
00:21:20,160 --> 00:21:23,920
Speaker 1: there's no bottleneck there because the tower has cut off

380
00:21:23,960 --> 00:21:26,600
Speaker 1: the number of people who can connect to it. WiFi

381
00:21:26,680 --> 00:21:29,280
Speaker 1: is different. WiFi. People just keep piling in and out.

382
00:21:29,320 --> 00:21:32,040
Speaker 1: There's like one big set of doors and everyone is

383
00:21:32,080 --> 00:21:33,680
Speaker 1: trying to get in and out that set of doors

384
00:21:33,720 --> 00:21:36,359
Speaker 1: at the same time. So the more people are trying

385
00:21:36,400 --> 00:21:40,320
Speaker 1: to access a WiFi spot, the slower you're going to experience.

386
00:21:40,400 --> 00:21:42,800
Speaker 1: The slower the data rates will be slower, data transfer

387
00:21:42,920 --> 00:21:46,359
Speaker 1: rates will be um because it does not limit the

388
00:21:46,480 --> 00:21:49,640
Speaker 1: number like y max does, So it's a different approach

389
00:21:49,720 --> 00:21:52,680
Speaker 1: rely UM and why MAX of course, is just one

390
00:21:52,840 --> 00:21:55,480
Speaker 1: of the four G solutions that we're looking at in

391
00:21:55,560 --> 00:21:58,040
Speaker 1: the in in the future. There are others as well

392
00:21:58,440 --> 00:22:01,760
Speaker 1: as LT, which is long term evolution. Looks it looks

393
00:22:01,800 --> 00:22:03,400
Speaker 1: like those two are going to be fighting it out

394
00:22:03,440 --> 00:22:07,160
Speaker 1: to be the four G standard, depending on on whom

395
00:22:07,200 --> 00:22:12,200
Speaker 1: you ask and where and what what company you happen

396
00:22:12,240 --> 00:22:15,080
Speaker 1: to be working for that is backing which standard. Here

397
00:22:15,080 --> 00:22:18,600
Speaker 1: in Atlanta we're actually seeing WiMAX now up and a

398
00:22:18,640 --> 00:22:21,120
Speaker 1: few other cities in the United States also have Wi

399
00:22:21,200 --> 00:22:24,080
Speaker 1: max now and more are expected to get it within

400
00:22:24,480 --> 00:22:27,320
Speaker 1: the next year. YEP, but LT is on its way,

401
00:22:27,320 --> 00:22:30,480
Speaker 1: I'm I'm pretty sure. And it's also that's also being

402
00:22:31,160 --> 00:22:34,439
Speaker 1: giving the UH the fast track and development. I do

403
00:22:34,480 --> 00:22:36,679
Speaker 1: want to clarify though, just to make certain that everyone

404
00:22:36,760 --> 00:22:39,960
Speaker 1: understands that if you have a Wi Fi card, a

405
00:22:40,080 --> 00:22:43,320
Speaker 1: O two, DON eleven, a b G or n UM,

406
00:22:43,359 --> 00:22:46,080
Speaker 1: those may or may not be compatible with you know,

407
00:22:46,280 --> 00:22:50,840
Speaker 1: a a particular card, or you know, some plug in

408
00:22:50,920 --> 00:22:53,720
Speaker 1: for your computer. But Bluetooth and Wi Max are going

409
00:22:53,760 --> 00:22:57,440
Speaker 1: to require their own separate thing. They're not they're not related.

410
00:22:57,480 --> 00:22:59,920
Speaker 1: You can't get one card, as far as I know,

411
00:23:00,560 --> 00:23:02,159
Speaker 1: you can't get one card that will get all of

412
00:23:02,200 --> 00:23:04,960
Speaker 1: those frequencies you know, in one thing that you can

413
00:23:04,960 --> 00:23:09,320
Speaker 1: plug into your machine. You're looking at probably three. Yeah,

414
00:23:09,760 --> 00:23:12,120
Speaker 1: although I guess you could argue that y max could

415
00:23:12,119 --> 00:23:15,880
Speaker 1: replace WiFi, except unless you're actually, well, if you're doing

416
00:23:15,920 --> 00:23:18,400
Speaker 1: home networking stuff, if you're trying to actually transfer data

417
00:23:18,440 --> 00:23:22,200
Speaker 1: between machines in your home network, then you will need something.

418
00:23:22,600 --> 00:23:26,040
Speaker 1: Because y max it's it's reporting back to the internet

419
00:23:26,080 --> 00:23:30,080
Speaker 1: service provider. It's not it's not a home networking solution. Well, okay,

420
00:23:30,680 --> 00:23:34,320
Speaker 1: that's actually a good point, because, um, the the particular

421
00:23:34,520 --> 00:23:37,840
Speaker 1: y Max provider that is advertising in the Atlanta area

422
00:23:37,920 --> 00:23:40,320
Speaker 1: shows off that you can have your laptop with you

423
00:23:40,880 --> 00:23:43,760
Speaker 1: and get access anywhere. You could be on the bus,

424
00:23:43,800 --> 00:23:45,960
Speaker 1: you could be you know, at an sidewalk cafe, you

425
00:23:45,960 --> 00:23:47,440
Speaker 1: could be at your home and you're still going to

426
00:23:47,520 --> 00:23:50,800
Speaker 1: get your wy max speed. Well that's great. However, if

427
00:23:50,840 --> 00:23:53,000
Speaker 1: you're using basically what they're showing off as a as

428
00:23:53,600 --> 00:23:58,200
Speaker 1: a dongle type card modem thing. Um, that's the scientific

429
00:23:58,280 --> 00:24:01,680
Speaker 1: term for it, type mode them card thing. Yes, yes,

430
00:24:01,760 --> 00:24:05,640
Speaker 1: I think it's on the box. Okay, okay, So anyway,

431
00:24:05,760 --> 00:24:07,240
Speaker 1: you plug the thing in the side of your computer,

432
00:24:07,320 --> 00:24:09,320
Speaker 1: you can get it and you can go anywhere. What

433
00:24:09,359 --> 00:24:11,399
Speaker 1: happens if you go home and you want to hook up,

434
00:24:11,520 --> 00:24:15,960
Speaker 1: say your spouse is computer, Well, now you kind of

435
00:24:16,119 --> 00:24:19,480
Speaker 1: need the internet. We'll see, that's that's going to do

436
00:24:19,560 --> 00:24:24,320
Speaker 1: with it. Okay, So then you're stuck. That's no, no

437
00:24:24,400 --> 00:24:26,560
Speaker 1: more home networking if all you have is that one

438
00:24:26,640 --> 00:24:31,000
Speaker 1: type of you know, connectivity, you know, they offer this

439
00:24:31,080 --> 00:24:33,919
Speaker 1: the wmax provider also offers a home modem and then

440
00:24:33,920 --> 00:24:36,040
Speaker 1: you can plug that into wave WiFi connection. But if

441
00:24:36,040 --> 00:24:38,720
Speaker 1: you want to get you know, the y max all

442
00:24:38,760 --> 00:24:41,840
Speaker 1: around town, you're gonna have to have the portable. Yeah,

443
00:24:42,200 --> 00:24:44,760
Speaker 1: so that's that's a difference. Does have it might actually

444
00:24:44,760 --> 00:24:47,800
Speaker 1: have a WiMAX and a WiFi Well yeah, they Yeah,

445
00:24:47,800 --> 00:24:50,360
Speaker 1: that's true, that's true. I've seen I've seen the packages

446
00:24:50,400 --> 00:24:53,240
Speaker 1: I've seen usually involved you can get one of each.

447
00:24:53,280 --> 00:24:55,439
Speaker 1: You can get one that's the home solution where you

448
00:24:55,560 --> 00:24:58,199
Speaker 1: you hook that up to your router. So you have

449
00:24:58,320 --> 00:25:02,160
Speaker 1: to buy both of them, yes, but but it's there's

450
00:25:02,200 --> 00:25:04,560
Speaker 1: some that's like a package deal though, so you're getting

451
00:25:04,600 --> 00:25:11,280
Speaker 1: a discount as opposed to if you were buying each separately. Yes, yes, so, yes,

452
00:25:11,320 --> 00:25:13,800
Speaker 1: you would still have to have your wireless router, which

453
00:25:13,840 --> 00:25:15,720
Speaker 1: would that's working on the WiFi if you want to

454
00:25:15,720 --> 00:25:18,400
Speaker 1: hook up all your computers, yes, exactly, and within your home,

455
00:25:18,720 --> 00:25:20,760
Speaker 1: and then you would have the y max dongle for

456
00:25:20,880 --> 00:25:25,960
Speaker 1: whichever computer you have designated as the the main one

457
00:25:26,000 --> 00:25:28,040
Speaker 1: whenever you're heading outside the house and you want to

458
00:25:28,080 --> 00:25:30,280
Speaker 1: be able to hook directly to your I s P.

459
00:25:30,359 --> 00:25:31,639
Speaker 1: The nice thing about that is you don't have to

460
00:25:31,640 --> 00:25:34,840
Speaker 1: pay for any other like WiFi services, any hotspots or

461
00:25:34,880 --> 00:25:37,040
Speaker 1: anything like that, and you don't have to you don't

462
00:25:37,040 --> 00:25:39,880
Speaker 1: have to depend upon no. Yeah, because with the wax range, Yeah,

463
00:25:39,960 --> 00:25:42,399
Speaker 1: you're connecting right to the Wi max thing tower, not

464
00:25:42,400 --> 00:25:46,639
Speaker 1: not to WiFi networks. And so I know that's a

465
00:25:46,680 --> 00:25:50,119
Speaker 1: big problem for us us, being me and my wife,

466
00:25:50,760 --> 00:25:55,480
Speaker 1: we when we're traveling around UH town, we have to

467
00:25:55,560 --> 00:25:58,040
Speaker 1: hope that wherever we're going has a WiFi network and

468
00:25:58,080 --> 00:26:00,639
Speaker 1: that that hopefully it's a why find network where we

469
00:26:00,680 --> 00:26:03,080
Speaker 1: don't have to pay extra to get attached to it,

470
00:26:03,080 --> 00:26:06,240
Speaker 1: because when you're already paying uh an internet service provider

471
00:26:06,280 --> 00:26:08,320
Speaker 1: to get access to the internet, you kind of hate

472
00:26:08,320 --> 00:26:10,040
Speaker 1: the thought of having to pay again because you're like,

473
00:26:10,240 --> 00:26:13,480
Speaker 1: if we were home, we could access this based on

474
00:26:13,520 --> 00:26:16,760
Speaker 1: our plan, we wouldn't have to pay extra. So yeah,

475
00:26:16,760 --> 00:26:22,800
Speaker 1: we get a little yeah, mightily miffed. Great was the

476
00:26:22,840 --> 00:26:26,960
Speaker 1: message thereof all right, well I think that that pretty

477
00:26:27,000 --> 00:26:29,600
Speaker 1: much covers the whole WiFi angle. Yeah. I'm sure we've

478
00:26:29,640 --> 00:26:32,560
Speaker 1: confused everyone by now. I know I'm more confused than

479
00:26:32,600 --> 00:26:38,439
Speaker 1: when we started, so good job. Um well, you know,

480
00:26:38,680 --> 00:26:40,880
Speaker 1: I guess that means that it's time to wrap things

481
00:26:41,000 --> 00:26:47,480
Speaker 1: up with a little a listener mail. This listener mail

482
00:26:47,520 --> 00:26:50,480
Speaker 1: comes from Casey. Hey, guys, I love the podcast. I

483
00:26:50,520 --> 00:26:52,680
Speaker 1: had a quick question for you. I've heard that Mac

484
00:26:52,680 --> 00:26:56,119
Speaker 1: and Linux operating systems don't get viruses like Windows computers do.

485
00:26:56,400 --> 00:26:58,120
Speaker 1: As far as I can tell, I haven't even heard

486
00:26:58,119 --> 00:27:01,359
Speaker 1: of a virus protection software from my Leopard running operating system.

487
00:27:01,440 --> 00:27:03,840
Speaker 1: Is this because the Unix base that Mac and Lenox

488
00:27:03,880 --> 00:27:06,520
Speaker 1: were built on is less susceptible, or because Windows is

489
00:27:06,560 --> 00:27:08,679
Speaker 1: a little easier to target because of how mainstream they

490
00:27:08,680 --> 00:27:10,879
Speaker 1: are operating system is? Keep up the good work, and

491
00:27:10,920 --> 00:27:13,080
Speaker 1: I would love to hear the answer to this sometime,

492
00:27:13,520 --> 00:27:15,600
Speaker 1: o K. See. First of all, let's let's address a

493
00:27:15,600 --> 00:27:19,119
Speaker 1: couple of things. UH. Linux does not have a Unix

494
00:27:19,160 --> 00:27:24,960
Speaker 1: base technically, it is it was inspired Lennox was inspired

495
00:27:25,240 --> 00:27:28,480
Speaker 1: by Unix, or rather we should say Linus was inspired

496
00:27:28,480 --> 00:27:32,760
Speaker 1: by Unix. Actually he was inspired by um minix Minix,

497
00:27:32,880 --> 00:27:35,520
Speaker 1: which in turn was a a kind of open source

498
00:27:35,800 --> 00:27:39,240
Speaker 1: alternative to Unix. See, you have Unix, you had the

499
00:27:39,240 --> 00:27:41,800
Speaker 1: open source alternative to Unix called Minix. You had Lenis

500
00:27:41,800 --> 00:27:44,480
Speaker 1: Torvald's who was then inspired by Minix to create Linux.

501
00:27:45,359 --> 00:27:48,679
Speaker 1: So let's get that all the way. UM As for

502
00:27:49,920 --> 00:27:55,960
Speaker 1: are they just naturally less susceptible? Not technically, I mean there,

503
00:27:56,280 --> 00:28:00,280
Speaker 1: it's it's more challenging to create the UH something that

504
00:28:00,680 --> 00:28:04,600
Speaker 1: exploits a vulnerability in Linux or Mac because you've got,

505
00:28:05,080 --> 00:28:07,760
Speaker 1: within the case of Linux, you've got a community that

506
00:28:07,880 --> 00:28:10,480
Speaker 1: is dedicated to finding these things out and fixing them

507
00:28:10,480 --> 00:28:13,600
Speaker 1: before they become problems. It doesn't mean that it's impossible.

508
00:28:13,640 --> 00:28:16,359
Speaker 1: It just means it's more challenging because you've you know,

509
00:28:16,400 --> 00:28:21,280
Speaker 1: you've got the entire worldwide Linux community working on this stuff. Um.

510
00:28:21,320 --> 00:28:24,080
Speaker 1: Even though there are various distributions, and each distribution is

511
00:28:24,119 --> 00:28:28,080
Speaker 1: slightly different from each other distribution Mac, you've got a

512
00:28:28,119 --> 00:28:32,480
Speaker 1: closed system which is harder to get into and learn

513
00:28:32,560 --> 00:28:36,040
Speaker 1: how that works because Apple controls the whole Mac UH

514
00:28:36,119 --> 00:28:40,680
Speaker 1: situation from the hardware to the operating system. Even so,

515
00:28:40,880 --> 00:28:45,480
Speaker 1: it is possible to create UH programs that exploit vulnerabilities.

516
00:28:45,520 --> 00:28:49,440
Speaker 1: We've seen that both in MAX and in Linux systems. Recently,

517
00:28:49,480 --> 00:28:52,240
Speaker 1: we've seen some that went as that that even exploit

518
00:28:52,320 --> 00:28:57,640
Speaker 1: vulnerabilities or could exploit of vulnerability within the Linux kernel itself. Um,

519
00:28:57,680 --> 00:29:02,280
Speaker 1: that doesn't mean that there as vulnerable as a Windows system.

520
00:29:02,640 --> 00:29:05,160
Speaker 1: Your question of is Windows more vulnerable because it's more

521
00:29:05,200 --> 00:29:08,239
Speaker 1: popular In a way, Yes, it's certainly more popular with

522
00:29:08,280 --> 00:29:13,080
Speaker 1: hackers for one thing. I mean it's it's more accessible. Also,

523
00:29:13,320 --> 00:29:16,280
Speaker 1: more people are using Windows. So therefore your target is

524
00:29:16,320 --> 00:29:19,080
Speaker 1: You've got a target rich environment is what our friends

525
00:29:19,080 --> 00:29:21,720
Speaker 1: in the military would call it. It's it means that

526
00:29:21,760 --> 00:29:25,160
Speaker 1: if you do write some malicious software, you're gonna hit

527
00:29:25,320 --> 00:29:27,440
Speaker 1: way more victims if you do it for Windows, then

528
00:29:27,440 --> 00:29:29,440
Speaker 1: you're gonna hit if you use it for macor Linux,

529
00:29:29,520 --> 00:29:32,080
Speaker 1: just because there are more people using Windows out there

530
00:29:32,160 --> 00:29:34,920
Speaker 1: than the alternatives. But if you look at some of

531
00:29:34,920 --> 00:29:38,959
Speaker 1: the vulnerabilities that exploit server software, that's all Linux based stuff.

532
00:29:39,520 --> 00:29:41,600
Speaker 1: I mean almost all of it. Not not all of it.

533
00:29:41,680 --> 00:29:43,760
Speaker 1: Don't write me I know, not all of it, but

534
00:29:43,960 --> 00:29:47,280
Speaker 1: a great deal of it. So it is possible, it's

535
00:29:47,320 --> 00:29:50,640
Speaker 1: just not as common. Yeah, And there are there are

536
00:29:50,680 --> 00:29:55,520
Speaker 1: a couple of security providers who have written uh mac

537
00:29:55,680 --> 00:29:58,360
Speaker 1: virus software and has been out for many many years now.

538
00:29:58,880 --> 00:30:01,560
Speaker 1: Um at Actually I think snow Leppard came with some

539
00:30:01,680 --> 00:30:05,840
Speaker 1: anti virus in under the hood. Yeah, it's it's sort

540
00:30:05,880 --> 00:30:09,320
Speaker 1: of invisible. Actually, not like I've actually noticed that, let

541
00:30:09,320 --> 00:30:13,120
Speaker 1: me put it that way. Um, but but yeah, I mean,

542
00:30:13,360 --> 00:30:15,440
Speaker 1: and and the one, the one I would say that

543
00:30:15,600 --> 00:30:20,840
Speaker 1: is arguable arguably the largest. Um it's a company called Intego,

544
00:30:21,160 --> 00:30:26,200
Speaker 1: And they're the ones who always draw attention to vulnerabilities

545
00:30:26,200 --> 00:30:29,120
Speaker 1: when they are pointed out, and um, they usually get

546
00:30:29,320 --> 00:30:33,000
Speaker 1: sort of picked on. Uh and and uh, some of

547
00:30:33,000 --> 00:30:35,520
Speaker 1: the stuff that I've read, because they go, oh, yeah, well,

548
00:30:35,640 --> 00:30:37,600
Speaker 1: you guys are the ones writing the software. Of course,

549
00:30:37,600 --> 00:30:42,400
Speaker 1: that's what happens when samantech or or McAfee also points

550
00:30:42,400 --> 00:30:44,400
Speaker 1: out that there are vulnerabilities out there, I mean, they

551
00:30:44,400 --> 00:30:48,720
Speaker 1: have a vested interest in keeping that um in mind.

552
00:30:48,800 --> 00:30:50,400
Speaker 1: But a lot of and a lot of cases to

553
00:30:50,520 --> 00:30:56,400
Speaker 1: the Mac stuff scans for Windows uh um malware as well,

554
00:30:56,520 --> 00:30:58,560
Speaker 1: which is useful if you're running an Intel Mac and

555
00:30:58,600 --> 00:31:00,960
Speaker 1: happen to be running and happen to have an installation

556
00:31:01,000 --> 00:31:04,760
Speaker 1: of Windows and the Mac operating system on your Mac UM.

557
00:31:04,840 --> 00:31:07,120
Speaker 1: So you know, it can be handy. But a lot

558
00:31:07,120 --> 00:31:09,960
Speaker 1: of people in the Mac world still believe that their

559
00:31:10,080 --> 00:31:14,560
Speaker 1: position is very secure and do not use any virus

560
00:31:14,640 --> 00:31:16,840
Speaker 1: software right now. That does not mean if you have

561
00:31:16,880 --> 00:31:19,120
Speaker 1: a Mac or Linux machine that you should go clicking

562
00:31:19,120 --> 00:31:21,880
Speaker 1: on every single link and and installing every single application

563
00:31:21,920 --> 00:31:25,240
Speaker 1: you come across, because you never know when that that

564
00:31:25,560 --> 00:31:29,280
Speaker 1: vulnerability will be discovered and exploited. Uh. Here's the tricky

565
00:31:29,320 --> 00:31:32,360
Speaker 1: thing about hackers who find vulnerabilities. Some of them don't

566
00:31:32,400 --> 00:31:35,560
Speaker 1: make it public knowledge, and so it may be you

567
00:31:35,600 --> 00:31:38,160
Speaker 1: know that it's constantly a game of let's catch up

568
00:31:38,160 --> 00:31:41,320
Speaker 1: to what the hackers know and uh and then patch it.

569
00:31:41,600 --> 00:31:45,240
Speaker 1: So just be careful. Yeah, Max and Lenox machines aren't

570
00:31:45,240 --> 00:31:48,520
Speaker 1: gonna experience them as often as windows are, uh, just

571
00:31:48,800 --> 00:31:52,320
Speaker 1: in general. But it's it's not outside the realm of possibility.

572
00:31:52,480 --> 00:31:54,800
Speaker 1: It's like to throw this one last thing out there. Um,

573
00:31:55,120 --> 00:31:57,760
Speaker 1: for everybody who is using any kind of computer on

574
00:31:57,800 --> 00:32:00,840
Speaker 1: any kind of operating system, keep in mind their vulnerabilities

575
00:32:00,840 --> 00:32:05,240
Speaker 1: in the operating system and uh, security software patch is

576
00:32:05,560 --> 00:32:08,760
Speaker 1: there to protect you from malware that has been discovered.

577
00:32:09,480 --> 00:32:11,920
Speaker 1: But as long as there's a vulnerability, anything that hasn't

578
00:32:11,920 --> 00:32:14,600
Speaker 1: been discovered, that's right. As long as there's a vulnerability

579
00:32:14,640 --> 00:32:16,840
Speaker 1: and someone is there to exploit it and nobody knows

580
00:32:16,840 --> 00:32:20,000
Speaker 1: about it yet, so it's best to keep up your

581
00:32:20,040 --> 00:32:22,320
Speaker 1: guard and pay attention to what you're doing. That is

582
00:32:22,320 --> 00:32:25,440
Speaker 1: the best security procedure you can have. Why is words

583
00:32:25,520 --> 00:32:29,240
Speaker 1: to live My from tech stuff. Thanks Casey. If any
