LightSquared urged the FCC to initiate a proceeding that would add a primary allocation permitting non-federal terrestrial mobile use of the 1675-1680 MHz band as an alternative to LightSquared’s use of the 1545-1555 MHz portion of the L band for…

terrestrial mobile broadband purposes. LightSquared petitioned the commission for a rulemaking proceeding as an effort to move forward with its effort to build a terrestrial network (CD Nov 6 p14). Comments submitted concerning LightSquared’s petition establish that “more than sufficient reasons exist to initiate such a proceeding,” LightSquared said in replies to comments in docket RM-11681 (http://xrl.us/bn77pr). The proposed allocation would facilitate the implementation of LightSquared’s 4G wireless network, “which would extend the benefits of competitive mobile broadband service to hundreds of millions of American consumers,” it said. LightSquared said it has no objection if the notice of proposed rulemaking also explores the types of issues raised by some of the commenters, including “sharing criteria with the incumbents that will remain in the 1675-1680 MHz band” and “compatibility with users in adjacent bands.” The Aerospace Industries Association supported the concerns raised by Lockheed Martin, the U.S. GPS Industry Council and the Coalition to Save Our GPS that urge the FCC to ensure that band can be shared with existing users. Allowing LightSquared to use its high-powered signals in this band “will likely pose many of the same issues as it did with regard to GPS and has the potential to jeopardize aviation safety and the efficient functioning of the national airspace system,” it said (http://xrl.us/bn77p7). Significant analysis should be employed “to determine if such sharing with federal systems is viable in 1675-1680 MHz,” AIA said.
