Personal communication systems (PCS) represent a rapidly growing and increasingly important segment of the telecommunication industry. The goal of PCS is to provide truly personal, cost-efficient communication services to users through portable handsets. In this paper, we present a survey on the research and development in PCS, emphasizing several important aspects such as the PCS concept, service requirements, system architecture, operation, and management. Some ongoing field trials are described as well. We focus on the wireless and the mobility-related features of PCS, discuss their impact on the system design and performance, and provide an overview of different technology choices.>
