Clearwire hates Wimax… well sorta
Clearwire hates Intel & WiMAX
In Clearwire’s recent 10-Q filing (SEC), Clearwire is locked down into using WiMAX. Barred from deploying LTE until late 2011 under its terms its negotiated with Intel. The contract which was outlined in the 10-Q filing restricts it from offering any non-WiMAX technology until Nov 28, 2011 
Another major hurdle in this is that even after Clearwire deploys WiMAX, it will still incur siginficant costs if it decided to deploy additional wireless technologies even if it’s “technologically superior or more cost effective” than WiMAX (ouch).
But I don’t think LTE will have any market well into 2012 and possibly later when devices and manufacturers come into play. These suppliers will only enter when a market is available and this is the short time Clearwire might need to see traction from now until then.
