802.16m, aka "WiMax 2," is expected to be approved by the Institute of Electrical and Electronics Engineers Inc. (IEEE) sometime this summer. The specification is said to enable 120Mbit/s downlink and 60Mbit/s uplink in an urban scenario using 4x2 MIMO (Multiple-Input/Multiple-Output) antennas on a 20MHz-wide channel. This is roughly double what current WiMax technology can achieve in lab conditions, of course -- actual data-rates to the device tend to be cut when used in real world circumstances. (See Predictions & Probabilities for 2010.)

Clearwire's CTO, John Saw, told Unstrung last week that the Kirkland, Wash.-based operator is watching the specification and won't be rushing to test the technology. "I don't think it's going to be this year. I think it's going to be much more likely 2011," says Saw of any trial timeline.

Saw thinks that 2012 is "possible" for commercial deployment of 802.16m. One of the chief benefits of the new specifications would be more "spectrally efficient" 20MHz channels -- as opposed to current 10MHz channels -- for delivering voice, video, and data.
