NEW YORK (AP) — Federal regulators are letting AT&T use an unused part of the airwaves for mobile broadband, potentially increasing the speed and capacity of its new LTE network.

The Federal Communications Commission voted Wednesday to revise the rules for a spectrum band known as Wireless Communications Services, or WCS. The order sets aside part of the band to protect Sirius XM Radio Inc.’s satellite service, which uses an adjacent band, and eases restrictions on the rest of the band.
