Hierarchical ATM based LAN/MAN backbone network for a personal communication network

This paper is concerned with the development of a backbone network for a high capacity personal communication network (PCN). It is expected that some of the 1st generation PCNs will be implemented on the DCS1800, which is a GSM based standard. The present backbone network of the GSM system is based on a conventional centralised structure. The paper examines the efficiency of the current GSM backbone network using circuit switched input traffic for both full rate and half rate speech coders. Finally the paper proposes an ATM LAN/MAN based backbone network which removes some of the inefficiencies of the existing GSM backbone network and can efficiently handle new services
