DCS-1900 system configuration

DCS-1900 is a proposed PCS system based on the GSM mobile telephone system. Like GSM, many configuration options and parameters must be selected by the base station manufacturer, or system operator. This paper examines parameter effects on system performance, to determine good configuration strategies. Issues considered include frequency plan, power control, base station synchronization, and DTX. A lower bound is presented for DCS-1900 uplink performance, and is used to determine the relationship between capacity and coverage. The best frequency plan is found to be a frequency hopped system with complete frequency reuse in every cell. Collisions between signals are controlled by restricting cell loading. The 1/3 frequency plan is shown to have at least 99% coverage with 0.24 loading, supporting 144 calls per cell in 30 MHz bandwidth.
