The performance of a CDMA system can be difficult to assess. Link budget
calculations can be used to verify performance margins for a particular set of
parameters, but fail to tell the “whole” story in an easy to understand, visual
way. In this paper, a graphical depiction of CDMA coverage vs. capacity is
shown to be a useful tool in evaluating the performance of a CDMA system.
The graphical results are used to show scenarios in which CDMA can be both
uplink and downlink limited. In particular, it is shown that in either case, the
addition of a low noise tower mounted amplifier (TMA) can benefit both...
