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. For this reason, smaller carriers are urging the FCC to mandate interoperability.
