Back in May, Clearwire said it would drop WiMax and turn to LTE technology for 4G services. At the time, the company said it had just enough money in the till to operate for a year. And things got worse for Clearwire when Sprint, the only company among the top four major U.S. carriers that offers WiMax 4G service, said it would aggressively rollout a 4G network and would support WiMax powered smartphones through 2012.
Sprint has already signed a long term deal to jointly develop LTE service with network wholesaler LightSquared. And while the carrier did recently raise $4 billion in notes due in 2018 and in 2021, there is no word if some of that cash will end up in Clearwire's pocket. Sprint owns 54% of Clearwire and some feel that the talk about default could be a ploy to force Sprint to purchase the company. Earlier this year, reports of a Sprint buyout of Clearwire surfaced, but obviously both sides never came to an agreement.
