As legislation was reintroduced in the Senate to require the FCC to allocate the 700 MHz D-block to public safety entities, the FCC adopted rules on Tuesday that prescribe the long-term evolution (LTE) standard as the technological foundation of a nationwide public safety wireless broadband network in the 700 MHz D-block. In establishing LTE as the common technology platform for the D-block, FCC Chairman Julius Genachowski observed that the agency’s action is “the exception and not the rule,” as the preferred course is to allow a competitive industry to make network design choices on its own. While citing “widespread agreement that a common interface is desirable and necessary to nationwide interoperability,” Genachowski told reporters that “having certainty about what the standards are should help increase [economies of] scale and reduce the cost” of building the D-block network. The FCC also adopted a further rulemaking notice that seeks comment on a range of technical issues that are intended to ensure interoperability and sufficient D-block coverage. Among these issues are (1) roaming and priority access between public safety networks, (2) network architecture, (3) network resiliency, (4) interference coordination and protection, and (5) interconnection with next-generation 911 networks. Although the FCC has endorsed an auction of the D-block to a commercial entity that would share its spectrum with emergency first responder agencies, there was no indication that the FCC intends to follow with auction rules soon. As Genachowski voiced hope that Congress would soon provide the agency with “clarity,” Commissioner Meredith Baker lauded the adoption of LTE as offering “much needed guidance to members of the public safety community.” Commissioner Robert McDowell voiced hope that, “down the road . . . we will examine and analyze ideas for ensuring that the full [D] block may be used more flexibly to support a complement of broadband uses and accommodate the ongoing rapid innovation in the mobile broadband sector.”
