WiMax's Narrow Window

5:35 PM -- Mobile WiMax will have a narrow window of opportunity to become a major 4G technology before Long Term Evolution (LTE) starts to take hold in the middle of the next decade, according to a new report from ABI Research .

The firm portrays the battle for 4G hearts and minds as a two-horse race between mobile WiMax and LTE. The analysts at ABI are already confident that the Qualcomm Inc. (Nasdaq: QCOM)-backed Ultra-Mobile Broadband (UMB) networking technology will not gain traction.

ABI is predicting that LTE subscribers will overtake WiMax users by 2015. This is simply because of the sheer weight of GSM carriers worldwide that will transition to LTE for 4G, the firm reckons.

I'm not, however, convinced that 4G is such an either/or proposition as it evolves. At the recent Mobile Congress Show, Vodafone Group plc (NYSE: VOD) and Picochip and others were all talking about how LTE and mobile WiMax may be combined in the future. — Dan Jones, Site Editor, Unstrung
