Numerous regional US carriers have called for AT&T to support their 700MHz bands, which would give them the LTE devices and roaming coverage they need to compete with national rivals. These networks may soon get their wish: as part of an FCC-led deal, AT&T has agreed to support LTE on the 700MHz A Block frequencies held by smaller providers. While AT&T is short on details, it's already modifying its network to support the additional bands. Compatible devices will arrive in a "reasonable time frame," the telecom giant says. The commitment doesn't address LTE interoperability problems with Verizon and other major US networks, but it should help at least a few tiny carriers stand a fighting chance in the 4G era.
