Mobile network operators are considering Enhanced Data rates for GSM Evolution (Edge) technology as a way of increasing data transmission rates without the expense of upgrading to 3G.
Edge has been seen as a slow and unnecessary step-up in data rates that will soon be surpassed by 3G.
The 150-180Kbps practical data transmission rate is half that of 3G, but twice as fast as GPRS.
Mobile operators are now looking at Edge as a viable option for customers using data services.
O2 told vnunet.com that it is currently assessing the technology. And analysts have indicated that the low cost of upgrading existing networks is attractive, especially with delays to 3G roll-outs.
Edge uses the same Time Division Multiple Access standard as GSM, meaning that existing cells can be used, and represents a relatively low cost upgrade to GPRS.
Sony Ericsson has announced that it will sell an Edge handset next year, joining Motorola and Nokia with their respective 6200 and T725 mobile phones.
