In a letter to Senate leaders, members of the High Tech DTV Coalition urged lawmakers to reject plans for a nationwide public safety network, proposed by Cyren Call, that would utilize 30 MHz of spectrum in the 700 MHz band, warning that the diversion of 700 MHz spectrum slated for auction later this year could jeopardize the completion of the digital television transition in 2009. Members of the coalition, including wireless association CTIA, Verizon Wireless, T-Mobile USA, Microsoft, and Intel, wrote to Senate Commerce Committee Chairman Daniel Inouye (D-HI) and to ranking committee member Ted Stevens (R-AK) early this week after learning of Senator John McCain’s (R-AZ) plan to introduce a bill that would reallocate a 30 MHz swath of spectrum in the 700 MHz band to a public safety broadband trust that would be used to construct a nationwide broadband network. Under the Cyren Call proposal, that network would be (1) built to public safety specifications, (2) managed privately, and (3) shared by public safety entities and the public sector. The spectrum sought by Cyren Call constitutes half of the spectrum that is to be reclaimed from analog TV broadcasters and auctioned to commercial wireless entities later this year. (An additional 24 MHz block of spectrum currently used by analog TV broadcasters will be reserved for public safety use.) Characterizing Cyren Call’s proposal and McCain’s proposed legislation as “in conflict with the DTV Act and other statutes enacted by Congress,” the coalition warned: “by not auctioning the commercial spectrum that will generate monies used to fund the DTV transition, Cyren Call would derail the entire transition process.” Noting that the plan could also endanger “public safety’s ability to obtain access to the 24 MHz that it so desperately needs for interoperability,” coalition members urged the FCC to create a single license for a nationwide public safety broadband network out of reclaimed 700 MHz spectrum now earmarked for public safety entities.
