Integrated base station-an approach

Abstract

Cellular telecommunications is one of the fastest growing and most challenging telecommunication applications ever. Today, it represents a large and continuously increasing percentage of new telephone subscribers around the world. In the long term, with the emergence of mobile satellite systems, the cellular digital telephony may, become the universal communication system. The design and development of the cellular systems viz. AMPS, CDMA and GSM etc. started off in parallel. In due course these systems have been standardized. With the advent of ASIC technology, and different cellular systems being standardized, it has become necessary to have an integrated system to enhance the virtual throughput of the network by operating different cellular systems in a single network. This paper touches upon the frequency spectrum issues of different systems and the possible network architecture with respect to the integrated base station (IBS) system. The possible IBS architecture is discussed including the conclusions drawn with respect to the integrated system design concepts.
