How would our members in the United States like to see a phone that could be used on any carrier? Qualcomm is developing a chip that aims to make that a reality. According to a recent FCC filing, Qualcomm is developing a radio chip that will be able to handle seven spectrum bands, including three below 1GHz. This new chip is called the WTR1605, and it would be ale to handle three sub-1GHz bands, three higher bands, and one "very high band (such as 2.5GHz)."

The picture above is just a snippet of the overall filing, but here are a few more details quoted from AndroidPolice:

Additionally, Qualcomm indicated in the filing that it will provide Lower A Block licensees that OEMs will be provided appropriate software for integration and testing to support LTE roaming on Bands 13, 17, and 25 (which is Sprint's PCS G Block).

The chip maker also tried to impress upon the FCC that it would be "inappropriate" to mandate the use of 28nm chips, as the transition to them (and the WTR1605L) is in its infancy. Further, it urges that the FCC should not mandate a Band 12/17 combination, as it is just one option for carriers "to meet their customer's interoperability needs, both within the 700MHz band and between any of the long list of other 4G bands."
Additionally, Qualcomm purposefully timed this new chip to coincide with their transition to the new 28nm process for chips. They have "accelerated development" on the chip and plan to begin shipping the first of them to manufacturers this July. The first devices using this chip will likely be in stores by the end of 2012. How's that for cool news?
