Abstract--Traditional design rules for cellular networks are not
directly applicable to code division multiple access (CDMA) net-
works where intercell interference is not mitigated by cell place-
ment and careful frequency planning. For transmission quality re-
quirements, a minimum signal-to-interference ratio (SIR) must be
achieved. The base-station location, its pilot-signal power (which
determines the size of the cell), and the transmission power of the
mobiles all affect the received SIR. In addition, because of the need
for power control in CDMA networks, large cells can cause a lot of
interference to adjacent small cells, posing another constraint to
design. In order to maximize the network capacity associated with
a design, we develop a methodology to calculate the sensitivity of
capacity to base-station location, pilot-signal power, and transmis-
sion power of each mobile. To alleviate the problem caused by dif-
ferent cell sizes, we introduce the power compensation factor, by
which the nominal power of the mobiles in every cell is adjusted.
