Speaker 1: Brought to you by the reinvented two thousand twelve camera.
Speaker 1: It's ready. Are you get in touch with technology with
Speaker 1: tech Stuff from how stuff works dot Com. Join Josh
Speaker 1: and Chuck, the guys who bring you stuff you should know,
Speaker 1: as they take a trip around the world to help
Speaker 1: you get smarter in a topsy turv economy. Check out
Speaker 1: the all new super Stuff Guide to the Economy from
Speaker 1: how stuff Works dot Com, available now exclusively on iTunes.
Speaker 1: Hi there, everybody, welcome to tech Stuff. My name is
Speaker 1: Chris Polette. I'm an editor here at how stuff works
Speaker 1: dot com and sitting next to me as usual as
Speaker 1: senior writer Jonathan Stricklandoha. All right. I wasn't expecting that.
Speaker 1: I know you weren't. All right, well, so so why
Speaker 1: the aloha? No reason? I just like to change it
Speaker 1: up every now and then. All right, and multicultural kind
Speaker 1: of guy. I figured you were thinking of pineapples. Now,
Speaker 1: I think I'll end this with mohallow. I think Mr
Speaker 1: Calicanus will have a word to save. Why don't we
Speaker 1: move on to our topic? All right, So today we're
Speaker 1: going to talk about communications, actually long distance. Maybe maybe
Speaker 1: somebody will be saying aloha and mahala to you. Yeah,
Speaker 1: perhaps some roaming. Yeah, because we're gonna talk about cellular communications.
Speaker 1: We've had a lot of emails come in about, you know,
Speaker 1: discussing things like the two G network, the three G network,
Speaker 1: the uh, the the eagerly awaited four gene network. Uh
Speaker 1: kind of too, sort of demystify these terms, kind of
Speaker 1: explain what they mean, and uh, why you should be
Speaker 1: concerned about what kind of phone you have or if
Speaker 1: you should be concerned. Um, and yeah, some of this
Speaker 1: came from just from the last year's release of the
Speaker 1: iPhone three G, which caused a lot of confusion among
Speaker 1: I would say, lay people who aren't really familiar with
Speaker 1: the whole two G three G thing in the first place. Right. Well, yeah,
Speaker 1: I mean it's really not all that surprising when you
Speaker 1: think about it, because Apple for a while there um
Speaker 1: was releasing new generations of IBM S power PC processors,
Speaker 1: and they'd have they had the G three and the
Speaker 1: G four Max. Right, So so you know, it makes
Speaker 1: sense that people would be a little surprised. Um. You know,
Speaker 1: I actually had somebody right in and say, hey, that's
Speaker 1: a picture of the three G iPhone, not the second
Speaker 1: generation iPhone. Well, the second generation, second generation iPhone is
Speaker 1: the three because it's not three G, it's G three
Speaker 1: or wait two right, G two? So yeah, alright, so
Speaker 1: here's where this whole confusion. See even we get confused,
Speaker 1: and it happens to the best of us. Um yeah,
Speaker 1: so yeah, the second generation iPhone is a three G phone.
Speaker 1: And that's because the three G does not refer to
Speaker 1: the phone's generation, but rather the the technology, the cellular
Speaker 1: technology that phone communicates across right right. As a matter
Speaker 1: of fact, people are wondering what they're rumors right now
Speaker 1: swirling about the next generation iPhone, and they're wondering what
Speaker 1: to call it because it won't be the three G
Speaker 1: G three iPhone it that would just be silly. And
Speaker 1: then they're calling it the G four anyway, Well, it's
Speaker 1: not really a fourth generation iPhone. Why don't we just
Speaker 1: call it Steve, Yeah, I think we'll be like that.
Speaker 1: We'll just call it the jobs so um. So here,
Speaker 1: currently in the United States, we're kind of in a
Speaker 1: transitionary period where we're going from a two G network
Speaker 1: and into a three G network. Um. Three G coverage
Speaker 1: in the United States is is much better than it
Speaker 1: was this time last year, but it's still it's still
Speaker 1: one of those things that's growing, um city by city,
Speaker 1: And not every carrier has a three G network. Um.
Speaker 1: This this is technology. I mean, it's stuff that you know,
Speaker 1: hardware and software have to be in place for these
Speaker 1: networks to work, and not all the carriers are are
Speaker 1: up to speed on that, at least not in the
Speaker 1: United States now. Granted, in other parts of the world
Speaker 1: they've had three G for a while now and UH.
Speaker 1: And there's certain parts of the United States where they've
Speaker 1: had it for a while, like San Francisco that you
Speaker 1: know who to thunk it, but other places just got it,
Speaker 1: like within the last twelve months or so now. So
Speaker 1: the different generations, you can kind of divide them up
Speaker 1: by two different things. The technology G they used to
Speaker 1: transmit signals through the cellular network and the speed through
Speaker 1: UH that those signals have. You know, so like a
Speaker 1: two G phone is going to transmit data and UH
Speaker 1: calls at a lower speed than a three G phone.
Speaker 1: In general, it depends on the It depends on the
Speaker 1: technology too. It depends on the technology. It depends on
Speaker 1: it actually depends on a lot of things. So we
Speaker 1: have to talk in a lot of generalities here, but
Speaker 1: let's let's break it down first. Like I was gonna
Speaker 1: talk about two G uh, they're there are two predominant
Speaker 1: technologies in the two G networks. UM. Most of the
Speaker 1: world uses G s M, which is a UH. It's
Speaker 1: based off time division multiple access technology or t d
Speaker 1: M A right, right, So like Europe, Africa, Asia, a
Speaker 1: lot of these places they're using G s M. But
Speaker 1: in the good old US of A, we decided to
Speaker 1: kind of adopt another technology, UM and and some of
Speaker 1: the carriers are still using that, and that's called code
Speaker 1: division multiple access technology or c d M. A. That's right. Actually,
Speaker 1: if you're wondering where G s M came came from,
Speaker 1: it's actually from A a French acronym. The a Confederation
Speaker 1: of European Posts and Telecommunications found of the group speciel
Speaker 1: Mobile in two and yes that's two. That's you know,
Speaker 1: twenty seven years ago, and they're the ones who basically
Speaker 1: developed the standard known as G s M. And then
Speaker 1: the acronym comes from them. Now for US RAT speaking
Speaker 1: folks as not speaking by that, I mean those who
Speaker 1: speak English or American. If you prefer UM G s M,
Speaker 1: we usually just go ahead and knock that out into
Speaker 1: Global System for Mobile Communications. Yeah, so it's not the
Speaker 1: the the true origin of the acronym, but hey, that's
Speaker 1: how we Americans like to do things, gosh darn it.
Speaker 1: So anyway, these two different technologies, they transmit information across
Speaker 1: radio signals in different ways, and because of that, they're
Speaker 1: not automatically compatible with one another. In fact, they're they're incompatible.
Speaker 1: So if you have a G S M phone, you
Speaker 1: can't necessarily switch to a C d M A network.
Speaker 1: So if you don't have any G s M coverage
Speaker 1: in the area you're in, you're kind of stuck. And
Speaker 1: that was one of the big problems of the US
Speaker 1: for a really long time was that a lot of
Speaker 1: the rural areas had C d M A coverage but
Speaker 1: not G s M coverage. So if you started driving
Speaker 1: across the United States, you would find big patches of
Speaker 1: areas where you had no service. Um. Since then, there
Speaker 1: have been some systems put in where you can use
Speaker 1: one phone over an other carriers network, but you usually
Speaker 1: end up having to pay some pretty big roaming charges um.
Speaker 1: At least until fairly recently, a lot of the phone
Speaker 1: carriers now I've realized that that tends to drive customers away,
Speaker 1: and so they've they've taken that into account. But yeah,
Speaker 1: and in in this case, it's still a matter of
Speaker 1: G s M phones using other GSM networks and c
Speaker 1: d M A phones using other c d M A networks. Um.
Speaker 1: And if you're wondering sort of in a in a
Speaker 1: broad path, which camp your provider falls into. Um, if
Speaker 1: you're using Verizon Wireless or Sprint, next heel, Um, those
Speaker 1: are c d M A and uh T Mobile and
Speaker 1: a T and T are using g s M. Um.
Speaker 1: You can also find out if you if you are
Speaker 1: blindfolded and or you know, somebody had rubbed off all
Speaker 1: the markings from your phone and they're not going to
Speaker 1: do that. That's why they subsidize your phone. They put
Speaker 1: their brand all over it. Um. But say you had
Speaker 1: to look at the back of a phone that didn't
Speaker 1: have a brand and go, how would I find out
Speaker 1: which one this is? If you were to take the
Speaker 1: battery out and look underneath, if it's got a simcard,
Speaker 1: that's as phone. Yeah. The nice thing about g S
Speaker 1: M phones is that if you if you have multiple
Speaker 1: simcards and you have a different simcard for every you
Speaker 1: know cell phone carrier, you can switch those out and
Speaker 1: then you're not even roaming anymore. Like if you move
Speaker 1: from one carrier's GSM network into another and you happen
Speaker 1: to have a simcard for that carrier, you can switch
Speaker 1: them out and you're you're just fine. Um. There's still
Speaker 1: some problems if you are traveling overseas because they transmit
Speaker 1: cellular information on different frequencies. So if your phone does
Speaker 1: not is not capable of transmitting in the same frequencies
Speaker 1: as the carrier around you uses, you're still out of luck.
Speaker 1: It's just not going to be able to communicate with
Speaker 1: the network. That's uh. That's what you see when you're
Speaker 1: looking at phone specs are looking for a new phone
Speaker 1: and you see triband or quad band, Um, that's what
Speaker 1: they're talking about. Or if you see the phrase world phones,
Speaker 1: that's basically what it's talking about. For GSM. There are
Speaker 1: actually four uh frequencies that I'm aware of that are
Speaker 1: used in different places around the world. Um. And the
Speaker 1: more frequencies you use, I mean they're still using g
Speaker 1: s M, but you know, you may or may not
Speaker 1: find a signal. And if you're using c d M
Speaker 1: c d M A, you're gonna have a much more
Speaker 1: difficult time finding a signal. Yeah, especially yeah, traveling abroad,
Speaker 1: because like like we said, c d M A is
Speaker 1: one of those technologies that really got a foothold in
Speaker 1: the United States and pretty much everywhere else adopted G
Speaker 1: s M. You may wonder why that is. It's because
Speaker 1: a lot of the European countries, uh, the governments of
Speaker 1: those countries mandated a specific technology, and in the US
Speaker 1: that's generally considered kind of anti competitive, and so the
Speaker 1: U S takes a lass a fair approach and they
Speaker 1: decide not to They say, well, you know, we're not
Speaker 1: gonna mandate which one is used, which sounds good except
Speaker 1: for the ends up being kind of confusing for the consumer.
Speaker 1: To make matters even more confusing. You may have seen
Speaker 1: c d M A or G s M under other
Speaker 1: code names like E V d O and EDGE. Well,
Speaker 1: those refer to the different kinds of technology, and they're
Speaker 1: actually different forms of three g r UM edges. One
Speaker 1: of them that's probably well known. UM. I think the
Speaker 1: first place I saw it once when they were starting
Speaker 1: to talk about the three G I phone and they
Speaker 1: were saying, well, it will be compatible with the Edge network. Um,
Speaker 1: they talked about I remember reading articles about how T
Speaker 1: Mobile wasn't even on Edge yet, and that was one
Speaker 1: of the things with the uh the G one. You
Speaker 1: may have heard of this, This phone from HTC uses
Speaker 1: the Google Android operating system. I'm somewhat familiar with it. Yeah, yeah,
Speaker 1: well they that was one of the things, uh, you
Speaker 1: know that they did. But E V D O and
Speaker 1: Edge are you know next well, theoretically next generation technologies. Yes,
Speaker 1: some might say two point five instead of three. Because
Speaker 1: here's the other thing is that when we're talking about
Speaker 1: these technologies, uh, there are organizations that are in place
Speaker 1: to try and standardize these technologies as best they can,
Speaker 1: but you're still talking about a range of capabilities, um,
Speaker 1: and so it gets kind of confusing. You know. You
Speaker 1: start seeing things like the two G speeds sort of
Speaker 1: bleed into the lower end of the three G speeds. Uh.
Speaker 1: So then you might say, okay, well, this is really
Speaker 1: a two point five G phone or two point seven
Speaker 1: five G phone, because it's faster than a two G phone,
Speaker 1: but it's not as fast as what three G is
Speaker 1: supposed to be. Yeah, it definitely does not make life
Speaker 1: easier you know, to understand all this stuff, right, well,
Speaker 1: I mean, just to put some numbers behind it, EDGE,
Speaker 1: which is UM, the enhanced Data G s M environment.
Speaker 1: We'll give you speeds of up to kilobits per second
Speaker 1: from what I understand, But that's on the road to
Speaker 1: what a lot of people are calling the true three G,
Speaker 1: which is Universal Mobile Telecommunication Servers or u MTS or
Speaker 1: is I like to call it. And uh, and that's
Speaker 1: two megabits per second. So um, you know that's that's
Speaker 1: about one and a half times faster. Actually now wait,
Speaker 1: never mind, it's like four times faster. Yeah, it's a
Speaker 1: it's really fast compared comparatively speaking. And we should also
Speaker 1: go ahead and point out that these these really high
Speaker 1: end speeds, they tend to be ideals. You know, you
Speaker 1: don't it's very rare that you're going to actually encounter
Speaker 1: that on your own phone, especially if you're moving, If
Speaker 1: you are in motion, then you're going to experience lower
Speaker 1: speeds no matter which network you are, and you're not
Speaker 1: going to have the ideal speed. And some of them
Speaker 1: you'll see, like in lab tests, they achieve speeds of
Speaker 1: blah blah blah, blah blah blah, that's because they're being
Speaker 1: still in a lab chair and not driving across town
Speaker 1: when you're having a conversation with a friend. And exactly
Speaker 1: it's in under ideal circumstances, which I don't know about you,
Speaker 1: but I am rarely in what I would consider ideal circumstances,
Speaker 1: unless I happen to be in Hawaii, in which case
Speaker 1: I often do think I'm in ideal circumstances. The other
Speaker 1: the other three G technology besides the U M T
Speaker 1: S is a c d M A two thousand. Actually
Speaker 1: there are more than just the two, but those are
Speaker 1: the two main ones. And again this is another generation
Speaker 1: of the c d M, a technology which we can
Speaker 1: expect to see because the United States doesn't hold you know,
Speaker 1: it doesn't like go of stuff that easily. I mean,
Speaker 1: do you remember when we try to switch to metric
Speaker 1: we're still actually we sort of gave up on it. Yeah,
Speaker 1: we totally gave up on it because Yeah, same sort
Speaker 1: of thing I think is going to happen here is
Speaker 1: that people who have who have this technology are not
Speaker 1: going to give up on it anytime soon. But um,
Speaker 1: I did read that a T and of course I
Speaker 1: read this at a T and T S website, So
Speaker 1: take it. Take this however, summer story supply, but A
Speaker 1: T and T said that there are three G speeds
Speaker 1: range from three point six to seven point two megabits
Speaker 1: per second in the lapse and they expect that by
Speaker 1: the end of two thousand nine they'll have it up
Speaker 1: to twenty megabits per second. That's pretty fast. And um,
Speaker 1: that's not fast, no, not compared to four G. Yes,
Speaker 1: is that where you were going, right, I was going.
Speaker 1: But we we need to finish three G. I think
Speaker 1: we're pretty much done. I mean we could talk about
Speaker 1: I guess next would be a long term evolution, right, yes,
Speaker 1: which is where we're getting into the four G. Yeah,
Speaker 1: that's long term evolution or LTT is the four G network.
Speaker 1: And uh speaking of your your reluctance to abandon technologies,
Speaker 1: it's kind of funny because the people who are moving
Speaker 1: to LTE are actually um sort of a hodgepodge of
Speaker 1: different people who are in different technologies now, UM A,
Speaker 1: T and T and Verizon. One of them is GSM,
Speaker 1: the other is c D M A. Both of them
Speaker 1: are saying that they'll have uh LTE networks in place.
Speaker 1: Um by uh, well and I'm saying when they say networks,
Speaker 1: I'm thinking maybe not with a capital and network, maybe
Speaker 1: like New York and places they're they're usually in scaled rollouts.
Speaker 1: So well, I mean, hey, let's let's play a cell
Speaker 1: phone tycoon for a minute. You know, you have you've
Speaker 1: built out this infrastructure that goes across the country more
Speaker 1: or less, and then you have to go update all
Speaker 1: that stuff, and you only have a limited budget. You
Speaker 1: know you're gonna hit the big places first where lots
Speaker 1: and lots and lots of people are UM and then
Speaker 1: move it out from there. So the thing is, though,
Speaker 1: that LTE will actually hit um a hundred megabits downstream
Speaker 1: and thirty upstream. UM. It actually uses a form of
Speaker 1: t C P I P, which is uh the protocol
Speaker 1: over which the Internet travels, and it's gonna be a
Speaker 1: lot more like using an Internet network than cell phones
Speaker 1: use now. So it'll be a lot more familiar, is
Speaker 1: what I mean. The technologies are actually sort of and
Speaker 1: to use Jonathan's favorite word converging, Yes, it'll it'll look
Speaker 1: more like a WiFi set up than a cellular setup,
Speaker 1: although it's not using WiFi. I mean that would that
Speaker 1: would be a nightmare to do that, because you would
Speaker 1: drop calls every time you walked fifteen feet. Now that
Speaker 1: that's true, but uh, you know it's it's rising and
Speaker 1: a T and T moving toward LTE and not another
Speaker 1: famous name, which is embracing a competing technology that we're
Speaker 1: all familiar with. It will never be rolled out. In
Speaker 1: my opinion, y Max and Sprint. Sprint is a big fan.
Speaker 1: They're they're teamed up with clear Wire. Actually admire the technology,
Speaker 1: and I hope they roll it out. Didn't they talk
Speaker 1: about this back in two thousand four something along those lines.
Speaker 1: So wy Max, Yeah, that's that's supposed to be one
Speaker 1: of those last mile solution problem things where you you say,
Speaker 1: how can we deliver uh, Internet connectivity to that last mile, uh,
Speaker 1: the last mile to the customer wirelessly. So it's kind
Speaker 1: of like it's it's using a wireless technology that um
Speaker 1: some people call it WiFi on steroids, but that's not
Speaker 1: really accurate. Um, it uses a completely different kind of
Speaker 1: protocol than WiFi. Uh, there are a certain number of
Speaker 1: open spots. Let's say, let's let's just kind of I'm
Speaker 1: going to use an example, kind of a concrete example,
Speaker 1: just imagine this to kind of get an idea of
Speaker 1: how why max works. Think of a round building that
Speaker 1: has forty doors, forty doorways, and as long as one
Speaker 1: of those doorways is open, you can get into that
Speaker 1: get in and out of that building, and get whatever
Speaker 1: information you need in and out of that building. That's
Speaker 1: kind of the way why max works. Once you hit
Speaker 1: a certain number of of folks hitting that that y
Speaker 1: max server or actually tower, I guess you could say
Speaker 1: you gotta go somewhere else. So um, but theoretically you
Speaker 1: could serve information at incredible speeds to the people that
Speaker 1: you are allowing into that particular service. I'm kind of
Speaker 1: with Pullette here. I don't know that we're ever going
Speaker 1: to see this because we've been promised it forever. I
Speaker 1: know there's certain cities that are rolling out y max networks,
Speaker 1: but yeah, it's um, it was supposed to be everywhere
Speaker 1: by now, and it just it hasn't arrived yet. UM.
Speaker 1: I think this goes back to the it's really expensive
Speaker 1: to roll out expensive, brand new technology to everywhere. Yeah,
Speaker 1: putting out a new infrastructure, whether you're talking about communications
Speaker 1: or transportation or you know, fuel or whatever. Anytime you're
Speaker 1: talking about rolling out a new infrastructure. That's expensive because
Speaker 1: first of all, you got to figure out how you're
Speaker 1: going to incorporate it into the existing infrastructure, and then
Speaker 1: you got to build the darned thing, and you gotta troubleshoot,
Speaker 1: and you gotta make sure it works, and you gotta
Speaker 1: bring it online. And I mean, it's it's a big,
Speaker 1: big deal. It's not like, you know, you flip a
Speaker 1: switch and suddenly everyone's on four G. Now. Um, I
Speaker 1: had read a report that said that, uh, that currently
Speaker 1: the expectation for widespread adoption of LTE in the US
Speaker 1: will will take at least until two thousand twelve. So
Speaker 1: um that would it would surprise me if we got
Speaker 1: there by two thousand twelve, considering how long it took
Speaker 1: us to get to three G. But let's hope springs eternal.
Speaker 1: I mean, the recession kind of also plays another nasty
Speaker 1: card into this whole thing. Companies are suddenly worried more
Speaker 1: about staying in business than they are about innovating, So
Speaker 1: we'll have to see how that goes. Um. I did
Speaker 1: hear that if you're stationary and you're using a top
Speaker 1: of the line for G network, you could expect up
Speaker 1: to one gig a bit per second eventually, which is
Speaker 1: that's a lot of data that's really really fast, and
Speaker 1: that's the that's the point at which you're gonna start seeing, uh.
Speaker 1: I think internet convergence versus you know, now you have
Speaker 1: DSL and cable, but at those speeds, so you know,
Speaker 1: that's beating out DSL and cable connections. Now even even
Speaker 1: the fiber optic connections are slower than that. And I've
Speaker 1: talked a lot about like netbooks converging with smartphones. I
Speaker 1: think at those speeds, you could really you see that happen,
Speaker 1: because suddenly cloud computing becomes a really distinct possibility. You know,
Speaker 1: you don't connect to a WiFi network, you connect to
Speaker 1: a four G network, You're gonna have much faster speeds
Speaker 1: than you would with WiFi. So at that point, cloud
Speaker 1: computing becomes really really attractive because you as long as
Speaker 1: you have that guaranteed high speed connection, you can take
Speaker 1: advantage of it. Yeah, that sounds good. I have nothing
Speaker 1: else about cellular phone networks, I know, Thank goodness, because
Speaker 1: you know what that means, right, And I can try
Speaker 1: and invent something real quick, hope. Sorry, it's time for
Speaker 1: listener mail. Today's listener mail comes from Simon. Simon says,
Speaker 1: Hey guys, Hi Simon, I was very intrigued by the
Speaker 1: podcast on expensive cables, although without much proof, I've always
Speaker 1: maintained that they are probably nothing but a big scam.
Speaker 1: At least if you have an average entertainment system and
Speaker 1: non bionic ears. You might haven't come in the mail yet.
Speaker 1: I do have a couple of ments on the study
Speaker 1: with coat hangers. As you say, it's only five people,
Speaker 1: so obviously not too scientific, but it seems to me
Speaker 1: that if two out of five could tell the difference,
Speaker 1: that might be a little bit more than just coincidence. Secondly,
Speaker 1: the fact that a coat hanger may produce the same
Speaker 1: quality of monster cables can be explained by the fact
Speaker 1: that it's made of a very thick wire, possibly capable
Speaker 1: of transmitting more information. I just did air quotes because
Speaker 1: he put quotes around that. So in that sense, a
Speaker 1: code hanger and a monster cable maybe better than regular cables.
Speaker 1: I love the podcast. Please keep up the great work. Thanks, Simon.
Speaker 1: Great really appreciate that. Um I agree with you, a
Speaker 1: sample size of five is not scientific at all. You
Speaker 1: can't call that scientific. It was really more of an experiment,
Speaker 1: like in the very loosest sense of the word, not
Speaker 1: in the scientific sense. Um. As for as for uh,
Speaker 1: a a thick wire carrying more information, Uh, you know, yeah,
Speaker 1: heavier gauge wire is capable of carrying a higher charge.
Speaker 1: I mean that makes sense. Um. But it also keep
Speaker 1: in mind that the the coat hangers had no shielding,
Speaker 1: so there was nothing to shield it from any interference,
Speaker 1: which is another one of the claims that high end
Speaker 1: cable UH manufacturers will make. They'll say this, these cables
Speaker 1: have a lot of shielding on them, and therefore the
Speaker 1: signal will be pure and you will you won't lose
Speaker 1: anything from the source to the destination. Yeah, that's true.
Speaker 1: And um, of course, the point is that not that
Speaker 1: monster cables are complete under fraud. They're actually very good cables.
Speaker 1: It's just that, uh, most people say, well, lesser cables
Speaker 1: can handle the same treatment or are are as good
Speaker 1: in certain circumstances. So you know, it's not a complete right,
Speaker 1: you know, you're not wasting your money, it's just you're
Speaker 1: maybe you could probably spend less money, Yeah, you could,
Speaker 1: You can probably spend less money and get the the
Speaker 1: experience that you really want. Um, you know, unless the
Speaker 1: experience you really want is to feel your wallet get lighter,
Speaker 1: in which case monster the way to go. Baby. Yeah.
Speaker 1: I mean if brand recognition is good for you, then yeah,
Speaker 1: it is a good quality product. Yeah. Alright, Well, now
Speaker 1: that we've managed to weasel out of that one, I
Speaker 1: think it's try to wrap this up. Remember, if you
Speaker 1: have any comments or suggestions or corrections, anything along those lines,
Speaker 1: you can send it to us text stuff at how
Speaker 1: stuff works dot com. We have blogs up. You can
Speaker 1: go to how stuff works dot com and you will
Speaker 1: see the listing of the blogs on the right hand side.
Speaker 1: Please come and visit. Definitely leave comments. Chris and I
Speaker 1: both interact on those blogs. So if you have a
Speaker 1: burning desire to say, hey, I love your podcast, and
Speaker 1: by the way, you misspelled blah blah blah, you can
Speaker 1: do that and then we will hang our heads in shame.
Speaker 1: I never misspelled blah blah blah, and neither do I actually,
Speaker 1: but you know you can other words. Yes, So please
Speaker 1: come to how stuff works dot com check out some
Speaker 1: of the articles there. We have plenty one cellular phones. Boy,
Speaker 1: I've got all the way through until the end. Cellular
Speaker 1: phones and UH and other subjects as well, and we
