Unlicensed

On Feb 28 the Federal Communications Commission voted to approve a new order paving the way for the expanded use of “white space broadband,” a promising technology that uses the spectrum freed from the shift to digital television to beam broadband into traditionally harder to reach rural areas. In 2017, Microsoft announced an ambitious plan to bring the technology to more than 2 million rural Americans across a dozen states by July 2022.

Facebook Terragraph gigabit wireless technology is gaining some traction with the news that Puerto Rican competitive carrier AeroNet will pilot the technology in Old San Juan (PR). The development follows other Terragraph deployments in Alameda (CA) and in Hungary. Terragraph works over 60 GHz spectrum, which is available for unlicensed use. It is even higher-frequency spectrum than the millimeter wave spectrum that AT&T and Verizon used for initial 5G deployments – which means it potentially could support higher speeds but over shorter distances.

Here's the agenda for the Federal Communications Commission's February open meeting:

Federal Communications Commission Chairman Ajit Pai proposed providing additional opportunities for unlicensed white space devices to deliver wireless broadband services in rural areas. Such devices operate in portions of the broadcast television bands (channels 2-35) and spectrum not being used for authorized services. Specifically, Chairman Pai is proposing to permit higher transmit power and higher antennas for fixed white space devices in rural areas.

On Nov 22, 2019, Rep Peter DeFazio (D-OR) wrote to Federal Communications Commission Chairman Ajit Pai about his growing concern with the FCC's "pattern of subordinating transportation safety to corporate broadband interests." He objected tot he FCC's proposal to repurpose portions of the 3.7-4.2 GHz spectrum band (C-band) for 5G purposes. He also objected to the FCC proposal to give away more than half the reserved 5.9 GHz connected vehicle spectrum to unlicensed Wi-Fi. 

House Transportation Committee Chairman Peter DeFazio (D-OR), Ranking Member Sam Graves (R-MO), and 36 Members of the committee sent a letter to the Federal Communications Commission to raise serious concerns with the FCC’s plan to redirect more than half the 5.9 GHz spectrum band. In December 2019, the FCC proposed to reallocate more than half of the 5.9 GHz radio frequency band (or Safety Band) to unlicensed operations, such as Wi-Fi.

Microsoft is pushing the Federal Communications Commission to respond to its May 2019 petition for rulemaking on expanding access to the so-called white spaces between TV channels. The company wants the FCC to allow more sharing in the broadcast band for unlicensed wireless. In meetings with FCC Commissioners Jessica Rosenworcel and Brendan Carr, Microsoft and its representatives came armed with a report outlining how wireless internet providers have been able to boost their throughput tenfold using TV white spaces.

Months after Federal Communications Commission Chairman Ajit Pai reiterated his support for plans to allocate more than 1,200 megahertz of unlicensed spectrum on the 6GHz band for Wi-Fi usage, the Wi-Fi industry is moving to hit the ground running with the additional real estate in 2020.

The Federal Communications Commission voted to take a fresh and comprehensive look at the 5.9 GHz (5.850-5.925 GHz) band, proposing rule changes to ensure that this spectrum supports its highest and best use for the American people. For the past two decades, the entire 75 megahertz of spectrum in the 5.9 GHz band has been reserved for use by Dedicated Short-Range Communications (DSRC), a radio service designed to enable vehicle-related communications. However, after 20 years, DSRC still has not been widely deployed, and this spectrum therefore generally remains unused.
