A report compiled by consulting firm Roberson & Associates (RA) concludes that long term evolution (LTE) technology is capable of providing multiple levels of priority access that would enable public safety entities to roam seamlessly on a shared public safetycommercial wireless broadband network that would operate on 700 MHz D-block frequencies. Presented during a Washington, DC briefing on Tuesday, the paper was commissioned by T-Mobile USA and Sprint Nextel, which both support auctions of D-block spectrum instead of direct reallocation of D-block channels to public safety as endorsed in recent weeks by the Obama Administration. In the words of RA CEO Dennis Roberson, the study “refutes the myth that commercial broadband networks can’t provide enhanced coverage and overflow capacity to a dedicated nationwide public safety data network” that, under the FCC’s current plan, would operate in tandem with D-block frequencies to be auctioned to a commercial wireless carrier. Specifically, the study claims that LTE can (1) guarantee automatic access to either a dedicated public safety or a shared public safety-commercial network, regardless of the level of congestion on that network, (2) provide public safety priority treatment over other network users, and (3) assure public safety certain levels of network capacity. To “realize the significant cost and operational benefits that accrue to public safety with commercial network sharing,” Roberson also noted that public safety radios should be fitted with the same LTE electronics that are available in all other LTE devices. While acknowledging opposition against a D-block auction in Congress as well as in the Obama Administration, an official of T-Mobile explained, “we’re trying to bring some substance to the debate.”
