Year 2011 will see LTE going live in a big way, as Verizon in the US and DoCoMo in Japan will begin wide-scale roll-outs by the end of 2010, said market research firm ABI Research.

Bhavya Khanna, analyst at ABI Research, said: "132 networks have reported trials or plans to launch LTE commercially, 32 more than the end of 2009. Verizon has also hinted at the availability of LTE-based handsets by May 2011."

Mr Khanna said: "However, don’t expect WiMAX to bow out just yet. Despite setbacks including Russia’s Yota switching to LTE, 188 WiMAX networks are now in trial or commercial operation worldwide.

"With India’s wireless broadband spectrum auction recently concluded, expect that number to grow in 2011. Clearwire, a WiMAX service provider in the US, continues to build out its network and add subscribers, buoyed by the launch of a popular WiMAX-capable handset, the HTC EVO 4G."

The firm said that the threat that WiMAX will face will come from TD-LTE, an alternative technology championed by China and Qualcomm that can operate on the same bandwidth as existing WiMAX networks. If this technology proves successful, it could see several WiMAX operators migrate to the LTE standard.

ABI research warns incumbent operators that they cannot afford to ignore their legacy 3G networks. Technology upgrades such as HSPA+ for WCDMA networks are also proving popular, helping incumbents cope with demands for increasing speeds and bandwidth efficiency. As of March 2010, over 41 network operators had trials or commercial launches of HSPA+ networks, including T-Mobile in the US and Vodafone in Turkey.
