Abstract
The wireless private branch exchange (PBX)system offers wireless telephone access in an officeenvironment. In a WPBX, several base stations areconnected to the PBX, and the PBX is connected to thepublic switched telephone network (PSTN). Since onlya small number of telephones are expected to be busy atthe same time, the capacity (number of the externallines) between the PBX and the PSTN is typically smaller than the sum of the capacities (radiochannels) of the individual base stations. It isimportant to determine the capacity of the WPBX tooptimize the performance of the system. This paperproposes an analytic model and a simulation model forWPBX resource planning. Based on the workload to theWPBX, our study provides the guidelines to determine thecapacities of the PBX and the base stations.
