The Mobility Division of the FCC’s Wireless Telecommunications Bureau today granted a waiver to the Association of American Railroads (AAR) to allow railroads to use signal boosters with an effective radiated power (ERP) of 30 watts to maintain communications between the front and rear of trains. The order adopted in WT docket 14-98 excludes the channels at the edge of the railroad frequencies to address concerns about the potential for interference to non-railroad channels. As a result, the waiver applies to frequencies from 452/457.90625 megahertz to 452/457.9625 MHz. Also, railroads operating under the waiver can only use single-channel Class A boosters, the order said.
