Jim et al - If I read Clark's post and the cross posts from Yhoo correctly, WLL (cdmaOne version, of course) may have capacity advantage of 6X over mobile, not 2X Clark previously estimated. Well 4 or 5 times anyway (three times the number of users per base station plus 30%(estimated) fewer basestations because the decreased mobility decreases the excess capacity needed in case users cluster). Nice to have firm numbers as mine were conservative estimates based on general knowledge of the technology. Note that, having now thought about this issue extensively, I think that it is probably true that GSM has problems getting the same difference between mobile and WLL. CDMAOne probably gets much of this extra capacity largely for free as the near-far problem largely disappears, but TDMA would still need to add in frequency allocation shuffling to get a big increase. This kind of shuffling is much easier for WLL than mobile, but it still requires positive effort. It would be interesting to know what the capacity advantage of CDMAOne is over GSM in a fixed system.
