In February, Congress enacted the most significant piece of spectrum legislation in almost 20 years. The new law has sweeping provisions providing billions for public safety broadband and for repurposing and repacking broadcasters through reverse auctions. It frees up spectrum to be auctioned for wireless broadband and encourages expanded use of white spaces and wireless towers. With the ink barely dry, significant disagreements have emerged over the meaning of many of the key provisions of the Act and over the respective roles of the FCC, NTIA, the First Responder Network Authority, and state and local governments. Stakeholders are also struggling to understand the complex multi-dimensional procedural steps through which the Act will be implemented, including the timing of key rulemakings, auctions, and the roll-out of the public safety broadband network.
