Abstract :
A radio planning methodology for IS-95 based CDMA networks is presented. Inherent to the planning methodology is a comprehensive performance characterization of both the forward and reverse links over a wide array of channel conditions. In addition, the link margin requirements under log-normal shadowing are addressed. Effects due to loading, Erlang variations and voice activity, soft and softer handoff status, forward power allocation and closed loop power control are incorporated into the network modeling. The output of the planning process are CDMA specific performance maps detailing forward and reverse link coverage and availability, interference margins and handoff regions. In addition, cell site specific data is derived including forward and reverse cell/sector loading, forward link power requirements and soft handoff overhead requirements
