A critical hmction of a mobile RF packet modem in a multi-cellular environment is to maximize its performance by using the most appropriate (clos- est) base station. In a multi-cellular environment, many different base stations may be necessary to give appropriate coverage and performance to a par- ticular area. The mobile RF packet modem that oper- ates in this domain must be capable ofselecting the base station that yields the best performance. The best performance is gained when the RF link between the base station and the mobile terminal is the strongest. The mobile terminal requires a metric that is related to the quality of the incoming RF signal to decide whether the current RF link is good enough and to keep listening to the current base station or to leave and roam for a better RF link. The opera- tion ofthe invention is to generate the required chan- nel quality metric for the mobile RF modem.
