It appears that Clear's upcoming LTE 4G trials have caused some alarm among Sprin'ts WiMAX subscribers. Matt Carter, president of 4G at Sprint Nextel, assured subscribers that Sprint is still focused on use of WiMax for 4G wireless networks.

Carter said, "Our position is that we are singularly focused around WiMax and there's no waivering on that view from us. Does the amount of wireless spectrum [Sprint has available] give us the opportunity in some time to to convert to LTE or run LTE alongside WiMax? Yes. We built the 4G network in a manner to give us that flexibility. But we don't want to confuse the market and our ecosystem of suppliers and customers. We are deploying WiMax."

Sprint currently has over 1 million customers using WiMAX 4G.

Well, some say Sprint and Clearwire will eventually support LTE, at least in tandem with WiMax. So, the LTE Vs WiMAX battle may end in a marriage. LTE 4G over Clearwire appears to be promising as it could offer speeds between 20 Mbit/sec. and 70 Mbit/sec., compared with 5 Mbit/sec. to 12 Mbit/sec. from other operators.
