Clark, Thanks for the education. I have very little experience with cell system design. I initially responded to the "bullfighter" because his arguments against WLL were devoid of technical merit. I usually just read learn and enjoy. Thanks again Pete >>Actually in a cell system, where the 'noise' in signal-to-noise ratio is from neighboring cells' signals, this is true to first order, but not completely true. The reason is that higher frequencies attenuate faster and thus interfere less with the neighboring cells even independent of cell spacing. In a typical city environment a 2GHz signal will be 3 or 4 dB more attenuated 1 km out than a 800 MHz signal, and that results in several dB improvement in S/N even for the same cell sizes.<<
