T-Mobile has rapidly expanded its LTE footprint in the last year, but there is only so much the carrier can do with existing spectrum licenses. It was previously rumored the Un-carrier was working on a spectrum deal with Verizon, and now its official. T-Mobile will hand over AWS licenses worth $950 million and throw in another $2.365 billion in cash to get its hands on new Block A 700MHz licenses.
According to a recent FCC filing, Qualcomm is hard at work on a new radio chipset that would support seven spectrum bands, including three below 1GHz. The introduction of this chipset could offer an effective solution to LTE spectrum fragmentation, which is a thorn in the side of manufacturers looking to cleanly execute broad product releases.
LTE fragmentation has also stirred debate among carriers, though. Smaller carriers operate within the Lower A block of the 700MHz band, in Band Class 12 while larger carriers like AT&T operate on the Lower B and C blocks in Band Class 17.
It seems there's been some renewed interest in the subject of Block C LTE "no locking" provisions after news that the Motorola RAZR will come equipped with a locked bootloader per Verizon's request. About four months ago, I published an article on this very topic. To summarize: Verizon can basically do almost anything it wants with handsets on its network in the name of reasonable network management - subject to a few limitations and caveats.
