Abstract
In cellular direct-sequence CDMA networks, each base station attempts to control the received power of signals from mobiles associated with the station. A simple upper bound on the uplink capacity per unit bandwidth is derived from consideration of the effects of fast fading and the limitations of power estimation. This bound decreases rapidly with increasing carrier frequency or vehicular speeds and indicates that a bandwidth expansion is necessary to maintain a specified uplink capacity.
