Personal Communications Systems (PCS) is a rapidly growing and important segment of the telecommunications industry. The ultimate goal of PCS is to provide a wide range of integrated wireless and wireline services, such as voice, data, video, and imaging etc., in one universal Personal Communications Network (PCN). We consider using the Cable Television (CATV) network as a communications network backbone to provide transport for ATM based Wireless PCS traffic, as one of the alternatives to network architecture choices. The objective is to achieve medium sharing of existing networks and hence conserve capital while providing minimum interruption to the ongoing services. The suitable signaling architecture for the proposed CATV/PSTN overlay is presented. A distributed communications architecture (DCPA/ASEs approach) is discussed and compared to the traditional centralized network and control (CP/B-ISUP approach) architecture. Call setup and handoff delay encountered in the proposed CATV/PCN overlay using these two schemes are compared. The network performances of the design model, such as the ATM end-to-end delay, AAL end-to-end delay, buffer requirement, cell access delay and cell loss are also investigated in this research work. Simulation models, consisting of 1 and 3 distributing centers (DC), each with 15 distributing points (DP), have been constructed for study. Network delay, throughput, capacity and coverage of the CATV/PCN overlay under various traffic loading situations are estimated. Finally, in order to support the ever increase demand for mobile communications, distributed antennas are considered to provide coverage enhancement in a simulcast arrangement. === Applied Science, Faculty of === Electrical and Computer Engineering, Department of === Graduate
