Summary: | 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
