Abstract

EDGE is a narrowband wireless data technology evolution for GSM networks. Some GSM and TDMA operators plan to deploy EDGE as an evolution from GPRS to provide higher data rates and sector throughput. EDGE and GPRS are interim steps for these operators as they evolve to 3G technologies. The paper provides an assessment of EDGE (enhanced data rates for GSM evolution) technology in an era of increasing data demand and scarce spectral resources. Mainly, the paper addresses the question of the viability of EDGE from technical design, performance, implementation, and deployment points of view. EDGE offers higher data rates compared to GPRS but requires better radio propagation conditions. The paper analyzes the spectrum efficiency of the technology, the sector throughput and the extent of the availability of higher data rates offered by EDGE.
