Experiments are conducted on a number of mobile radio systems that are suitable for operation in nondispersive microcellular networks. It becomes apparent that the selection of the type of modem and the number of its levels, the choice of speech codec to be used, and whether to deploy a channel codec, depends on the channel signal-to-noise ratio (SNR) and teletraffic demand, if the power consumption of the hand held portable is to be minimized. Following the implications of our limited number
