EDGE's Evolution

By Glenn Fleishman

Mobile base station makers to introduce double and quadruple speed EDGE: EDGE is criticized for being an also-ran technology, despite its wide use. It’s 2.5G, the mid-generation step between modem-speed/voice 2G and wanna-be broadband 3G. But EDGE’s evolution takes its top potential rate of 236 Kbps in the current implementation to 592 Kbps, InfoWorld reports. This is an advantage for countries and carriers that don’t have 3G rolled out, because existing spectrum and licenses can still be used. For some equipment, the upgrade is just a software change; for phones, new chips are needed. A future version of EDGE, EGRPS II, will boost downstream speeds to 1.2 Mbps and upstream to 473 Kbps.

Really curious about what equipment and which carriers will support this Edge Evolution. For instance, I use Sony-Ericsson's GC89 pcmcia radio modem card and it would be nice to get twice the speed on their current, painfully slow edge service with T-Mobile.

[Editor's note: As noted in the story, new handsets and chips will be needed for phones and cards, so nothing we use now will support the higher rates.-gf]
