A lot of hay has been made of Sprint and their new 4G network based off of WiMax, especially with the imminent launch of the HTC EVO.
But the fact remains, in terms of 4g technologies, WiMax may be the first but it's far from the default choice by many carriers in the U.S., let alone world-wide. Some feel this may be a dead-end for Sprint in the long run and if it's one thing Sprint doesn't need, it's another dud (cough, Palm Pre, cough).
Thankfully, Sprint was smart enough to leave options on the table.
To the point, Sprint has "...issued a "next generation network" request for proposal (RFP)" on their current fiber and they're looking at LTE:
"There's nothing that prevents us from... moving to LTE," said Kevin Packingham, senior VP of product and technology development at Sprint, speaking at the LTE event here. "We're doing a technology evaluation and making a decision on our core network and how we want to evolve that going forward."
And what about ol' WiMax? Looks like Sprint could have its cake and eat it too as they don't consider the two technologies "mutually exclusive". One could envision WiMax being deployed as a "hotspot" technology where LTE more ubiquitous. Of course, timing is everything and that could snag them a bit. But options are always good and at least Sprint didn't totally paint themselves into a corner. We hope.
