In a key decision that is expected to boost the deployment of mobile broadband, the FCC on Wednesday approved LightSquared’s request for waiver and modification of its mobile satellite service (MSS) and ancillary terrestrial component (ATC) licenses to enable LightSquared to provide wholesale network capacity to carriers that will in turn offer stand-alone terrestrial wireless broadband services to their customers. The FCC ruling represents an important step forward in LightSquared’s plan to deploy a nationwide LTE wireless broadband network. While acknowledging that the requested waiver contravenes the terms of the LightSquared MSS/ATC license that requires terrestrial service to be offered as part of an integrated mobile satellite service offering, the FCC determined that a grant was warranted, given the public interest benefits of the resulting expansion of wireless broadband services and LightSquared’s significant investment in the satellite-based portion of its network. Addressing interference concerns raised by adjacent federal government and global positioning system (GPS) spectrum users, the FCC conditioned approval on LightSquared’s participation in a working group through which the FCC would work with the National Telecommunications and Information Administration (NTIA), the GPS community, and federal government users to “study the potential for overload interference to GPS devices and to identify any measures necessary to prevent harmful interference to GPS.” The FCC also stipulated that “the process described for . . . addressing the interference concerns regarding GPS must be completed to the Commission’s satisfaction before LightSquared commences offering commercial service.” Although NTIA recently joined with several other government agencies in urging the FCC to defer action on the LightSquared waiver, NTIA Administrator Larry Strickling applauded the FCC for “requiring that . . . potential interference concerns be addressed before LightSquared begins offering commercial broadband service.” In a statement, LightSquared pledged to “work with all interested parties” to resolve interference concerns.
