Earlier today, in a development that will benefit WiFi users and make way for modern wireless vehicle safety capabilities, the U.S. Court of Appeals for the District of Columbia Circuit unanimously affirmed the Commission's November 2020 Order repurposing 45 MHz of fallow spectrum in the 5.9 GHz band for unlicensed use.
In a Statement, NCTA – The Internet & Television Association called the court's decision in Intelligent Transportation Society of America v. FCC "an enormous victory for American consumers," one that will lead to "even more reliable high-speed Wi-Fi and access to next-generation automotive safety applications."
In 1999, the FCC dedicated 75 MHz of beachfront spectrum to a proprietary vehicle safety technology that never lived up to its promise. Over twenty years later, the 5.9 GHz Order put that valuable wireless capacity to its highest and best use, making 30 MHz available for successor intelligent transportation systems technologies and repurposing the lower 45 MHz for WiFi and other unlicensed services.
Free State Foundation President Randolph May and I filed comments in support of the FCC's proposal. And in a Perspectives from FSF Scholars published shortly before the Commission adopted the 5.9 GHz Order, I argued that it represented "a fresh approach to this vastly underutilized spectrum that advances both public safety and the capabilities of WiFi networks."
Regrettably, in one of several recent high-profile instances of a breakdown in interagency spectrum coordination efforts necessitating process reform, the Department of Transportation raised objections to the Commission's proposal outside of established channels.
Eventually, several interested parties challenged the 5.9 GHz Order in court.
As Free State Foundation Director of Policy Studies and Senior Fellow Seth Cooper explained in a December 2021 post to the FSF Blog, consistent with the Supreme Court's 1968 decision in U.S. v. Southwest Cable Company, "[a] decision by the D.C. Circuit to uphold the 5.9 GHz Order would constitute a small but helpful step toward vindicating the FCC's 'unified jurisdiction and regulatory power' over commercial spectrum from interference by other federal agencies."
Today's decision does just that. In response to petitioners' claims that the 5.9 GHz Order "was arbitrary and capricious because it violated the Transportation Equity Act," the D.C. Circuit succinctly responded as follows: "It was not."
Specifically, the court held that:
[T]he Transportation Equity Act did not transfer away from the FCC its broad authority to manage the spectrum related to intelligent transportation systems. Instead, as the FCC noted, it simply required the FCC to account for the Department of Transportation's views and the needs of intelligent transportation systems when it does so. The FCC did that here.
