GSM/EDGE continued evolution

摘要

GSM/EDGE has evolved into the most widely deployed cellular telephony standard in the world, offering high-performance voice and data services. To keep GSM/EDGE competitive, even in years to come, Ericsson has proposed steps to further evolve the standard. The authors describe the proposed technology enhancements, which improve average and peak bit rates, latency, service coverage, and spectrum efficiency. Specific solutions include dual-antenna terminals, multi-carrier EDGE, mobility enhancements, reduced transmission time intervals, higher-order modulation, and new coding schemes. The combination of these solutions fulfills the requirements set by 3GPP.
