Abstract	The growing demand for mobile communication services as well as technological advances drive the new generation of Personal Communication Networks (PCNs). New or modified networks and communication protocols are required to support associated Personal communication Services (PCS). An ATM-based architecture has been proposed to support future PCS. The network would provide improved PCS performance for applications such as hand-off and call set up. CDMA technology is assumed as the air interface, with a bandwidth in each cell site of 2.5 MHz and a sectorization antenna with 3 sectors/cell. The PCS radio cell coverage size varies depending on geographic location; radii of 275 m and 981 m are proposed for microcells in metropolitan and urban areas, respectively. The topology of the proposed network is a star configuration which connects the base stations (BS) to the mobile switching centre (MSC). The proposed network which ! interconnects 16 switching centers can support up to 3.0 million potential PCS users with a coverage of 600 K m 2 in metropolitan area. Strategies such as fast hand-off routing and signalling schemes are presented based on the virtual connection tree concept. Radio cells with a 50 percent overlapping area for improving hand-off performance are considered. Radio cell radii are calculated in different environments with various market penetrations. Cell site overload probability for voice and data users within a connection tree region is studied. Network performance in terms of end-to-end delay, cell delay variation, and buffer occupancy are investigated in depth.
