EDGE – Enhanced Data rates for Global Evolution – has become a natural upgrade for GSM systems, providing fast internet access to the mass market and serving as an important complement to WCDMA/HSPA and in the future LTE networks. With EDGE Evolution, performance and capacity is significantly improved over existing infrastructure, delivering true mobile broadband services over the GSM/EDGE network.
Upgrading to EDGE has become a natural step for operators to offer high-performance mobile data services over GSM. EDGE presents a cost-efficient way to reach the mass market and boost the uptake of mobile data services.
EDGE combines efficient technology, a simple upgrade path, and support in a large proportion of GSM and WCDMA terminals to create a compelling business case. Three quarters of all GSM and UMTS terminals sold now support EDGE, from low to high-end.
EDGE is a viable alternative for providing Internet access in markets where fixed network infrastructure is yet to be established, as well as an important complement to mobile broadband services delivered over WCDMA/HSPA and in the future LTE networks. EDGE provides both a fast way to achieve good indoor and outdoor coverage, and to meet increasing demand for mobile Internet services through optimal use of available radio spectrum.
To build on the global success of EDGE, the GSM community has standardized EDGE Evolution, which further improves performance and capacity. EDGE Evolution more than doubles end-user bit-rates and reduces latency significantly. What is more, all this can be done using existing infrastructure, protecting current GSM and EDGE investments for many years to come.
