Several mobile phone operators and equipment manufacturers have teamed to test high-speed LTE (Long-Term Evolution) mobile phone technology, says Network World.

T-Mobile International, Orange and Vodafone have joined forces with vendors Alcatel-Lucent, Nokia Siemens, Nortel and Ericsson to begin trailing mobile broadband networks based on LTE technology, the companies said Thursday.

Cellular LTE and Mobile WiMax are vying for dominance in the emerging market for 4G (fourth-generation) networking services.

The LTE trial, which will begin later this month, will test mobile broadband peak data rates of more than 100M bps (bits per second). The high data speeds will be achieved through OFDM modulation and through multi-antenna technologies.

On Wednesday, Nokia Siemens demonstrated the use of “Virtual MIMO” in LTE networks. MIMO, already being used in Wi-Fi networks, combines multiple antennas at each end to minimize errors and optimize data speeds. Participants plan to use the test results in their ongoing LTE development and standardization efforts.

Commercial LTE service is planned in the 2009-2010 timeframe. DailyWireless has more on The Civil War in 4G.
