Clearwire Removes Obstacle to LTE Shift

Clearwire says it changed the terms of an agreement with Intel, one of its largest investors, that could eventually lead the way for Clearwire to switch to Long Term Evolution as its radio interface, ending its use of WiMAX. Clearwire and Sprint executives have said in the past they believe the two standards now are so similar it would not be difficult to adopt a unified air interface.

The new terms allow either Intel or Clearwire to exit the WiMAX agreement, which had until now forced Clearwire to use WiMAX through Nov. 28, 2011, with just 30 days notice. Those of you who believe Clearwire ultimately will switch to LTE can take that as a sign Clearwire might make the move before late 2011.

 CFO Erik E. Prusch reiterated the company's view that the overall ecosystem for 4G wireless was converging and as such, the market won’t have the technology wars in the future that it has seen in the past.

The technologies underlying LTE and WiMAX aren’t so far off as to make a transition from one to the other all that expensive in terms of the network costs, but devices that are currently running on the WiMAX network might need to be replaced if Clearwire implements a wholesale technology change on its radio network.
