Sprint is putting another nail in its WiMax coffin by confirming at an Orlando mobile carrier conference that it will no longer release new WiMax phones, instead relying on devices that run on its upcoming LTE 4G network.

It’s news likely to be watched closely by Bellevue-based wireless broadband provider Clearwire, which has received a recent cash infusion from Sprint and is itself planning to transition to a Long-Term Evolution network after initially staking its claim on WiMax.

At the Competitive Carriers Global Expo in Florida, FierceWireless states that Sprint Senior Vice President Bob Azzi confirmed no new WiMax phones will be released as Sprint wraps up final field integration tests of its new LTE network.  That network is expected to be ready mid-year, and Azzi indicates the tests have been going well.
