Page 49 1 station that's associated with that phone, up to the 2 cell tower. 3 phone that needs to make -- that it's -- that it's 4 intended for. 5 Then it will be beamed down to the cell So you can see that way you've got a 6 communication between the two phones. 7 going in one direction, but, of course, it's two 8 directions. 9 Q. I've shown this Now, Dr. Wells, you talked earlier about all 10 the different types of data that we can get and send 11 today on our phones. 12 13 14 Is it true of -- my children, my teenagers seem to think that bandwidth is unlimited? A. Unfortunately not, no. Now, one of the -- one 15 of the problems that we have in the cellular industry is 16 this limited bandwidth problem. 17 Basically what happens, when you make that 18 call from your cell phone up to a cell tower, the 19 traffic is carried on a radio wave, and that has a 20 particular frequency, and there's only a certain number 21 of those frequencies that are really available. 22 So what happens is, as Mr. Struhsaker said 23 earlier, that -- those frequencies are very jealously 24 guarded, and it's limited the number that you can use. 25 And what that does is that places a limit on Page 50 1 how many cell phones can actually be used within a cell. 2 So we call that the limited bandwidth problem. 3 Q. And so how do cell systems deal with this 4 limited bandwidth problem if everybody wants to use all 5 of these different types of data? 6 A. Well, there's various ways. The first way is 7 time division multiple access. 8 similar slide, but let me try and explain again how the 9 TDMA system works. 10 So forgive me showing a What I have shown here is on the left-hand 11 side is a base station with a cell tower, and it's going 12 to be transmitting these signals to these cell phones on 13 the right. 14 the -- the different time slots are allocated for 15 different phones. 16 And you saw that earlier. You saw about how The blue data goes to the blue phone; the red 17 data goes to the red phone; the green data goes to the 18 green phone. 19 Q. All right. 20 A. Well, no, it didn't. That's time division multiple access. And did that solve the problem? As we talked about 21 earlier and as you can see here, there are 22 inefficiencies with these systems. 23 transmitting voice, there's actually periods of time 24 where we stop, where information is not being exchanged. 25 As we -- if you were So if you use a rigid system like this, there Page 51 1 are inefficiencies with using it. 2 Q. Is TDM still used today? 3 A. It is still used today, yes. There are still 4 systems that use this. 5 around this, and a number of countries still use TDM 6 systems. A number of systems are based 7 Q. And where are those countries located? 8 A. All around the world, because these systems 9 are still supported as what we call a legacy system. 10 But a number of developing countries are still on these 11 sort of technologies. 12 13 14 Q. Were there other approaches that were used to try and solve this bandwidth problem? A. Yes. The other one, of course, is code 15 division multiple access, CDMA. 16 picture we looked at earlier, we have the base station 17 on the left that's transmitting to three phones on the 18 right-hand side. 19 actually put a code. 20 Again, using the And we send data together. We We put this language, as it was mentioned this 21 morning, onto each piece of direct address translation. 22 We send it across the air. 23 which code is associated with it. It can decode it. 24 can un-translate it, if you like. Then you can send 25 multiple messages at the same time. Each one of the phones knows It Page 160 1 CERTIFICATION 2 3 I HEREBY CERTIFY that the foregoing is a 4 true and correct transcript from the stenographic notes 5 of the proceedings in the above-entitled matter to the 6 best of our abilities. 7 8 9 /s/ Shea Sloan SHEA SLOAN, CSR 10 Official Court Reporter State of Texas No.: 11 Expiration Date: 3081 12/31/14 12 13 /s/ Judith Werlinger 14 JUDITH WERLINGER, CSR Deputy Official Court Reporter 15 State of Texas No.: Expiration Date 16 17 18 19 20 21 22 23 24 25 731 12/31/14
