I mentioned just a bit ago that there would be 4G WiMax coverage for 120M in the US by the end of the year. There are reports coming in that Clearwire has changed the terms of its agreement with Intel.
Intel is one of the major investors in Clearwire. The change came in the agreement between the two firms that would allow one of them out of WiMax support. Clearwire has reportedly changed from the agreement that required it to support WiMax until November 28 of 2011 to needing only a 30-day notice from either party to change.
The scuttlebutt is that this move could be in preparation for possible moving from WiMax to LTE in the future. Both of the 4G technologies are said to use similar underlying technology so such a move would be possible.
