Okay, EricL, I'm not going to enter acronym heaven [which is my vision of hell]. 3GSM is CDMA is UMTS is 3G is SETI is VW-40 is W-CDMA is DS-CDMA is cdma2000 is MC-CDMA is UTRA is UTRAN is enough. Yes, there are subtle differences between them, but I think I'll quit now. Sorry to those I forgot, such as the new Chinese standard.
The Ayn Rand Objectivists would be squirming - they like A is A or some such simple equation.
I asked the other Eric, but maybe you could tell us just what fraction of the total cost of a system is the air interface electronic gizzardry? You know, the stuff which crunches the numbers for soft handoff, rake receivers, power control and other necessary functions to make those wonderful CDMA phragmented photons zoom through the aether.
Don't count the optical fibre, switching gear and stuff which is in the foundations. Just the part which is dumped on top of GSM or ANSI-41 to make it fly.
Then, how much is the rest of the base station electronic gizzardry INCLUDING civil works necessary for extra base-stations if the system needs more of them for equal coverage. I suppose W-CDMA and cdma2000 in the same frequency and bandwidth would need the same geographical coverage, so that shouldn't be a problem. But it just might be, so I thought I'd ask. If W-CDMA is less spectrally efficient, as QUALCOMM says, then I suppose they'll need a few more basestations [by a small percentage].
Your assistance is appreciated,
My guess is that the air interface components are about 70% of the cost of a base station's electronics.
