FCC Opens Spectrum; Creates Citizens Broadband Radio Service
On April 17th, FCC Commissioners voted unanimously to expand the use of spectrum previously reserved for U.S. Army and Navy radar systems. The FCC Report and Order creates the Citizens Broadband Radio Service (CBRS) which establishes rules for shared use by licensed and unlicensed users.
This is a step forward to ensuring we are getting the most use out of the spectrum - by allowing different entities to share the spectrum when it is not being used in some geographic areas for the purpose it was originally allocated for. Milo Medin of Google explained this plan at Freedom to Connect - watch his presentation here.
According to the FCC Press Release [PDF], sharing will be managed with a three-tiered approach:
In addition to the protected incumbent tier, the Report and Order authorizes two commercial tiers of use in the Citizens Broadband Radio Service. The General Authorized Access tier, which allows any user with a certified device to operate without seeking any further Commission approval, will permit low-cost entry into the band, similar to unlicensed uses. A Priority Access tier will make geographically targeted, short-term priority rights to a portion of the band available through future spectrum auctions. One or more Spectrum Access Systems, operated by private commercial entities, will facilitate coexistence among the different user tiers.
Public Knowledge applauded the decision. Senior Vice President Harold Feld:
Today’s FCC’s actions lay the groundwork for changes in the very way we use wireless, allowing different levels of interference protection and network architecture that will make the wireless world of the future as radically different as the smartphone and the WiFi hotspot are from touchtone phones and the CB radios.
New America's Michael Calabrese, Director of New America's Wireless Future Project commended the FCC and pushed for more action:
"Today's bipartisan FCC vote to create a Citizens Broadband Service is a historic step that lays the foundation for spectrum sharing. While exclusive licensing will persist for many years, there is little left to be cleared for traditional auctions. There is, however, a potential spectrum superhighway of grossly underused federal and satellite spectrum that needs to be opened for low-power sharing by both unlicensed users and by priority access licensees who pay for interference protection. The Commission should move quickly to extend this new Citizens Broadband Service to other similar bands with immense fallow capacity, thereby ushering in a new era of wireless broadband abundance."
The Verge quoted FCC Chairman Tom Wheeler:
"Since they don’t make spectrum anymore, and since spectrum is the pathway of the 21st century, we have to figure out how we’re going to live with a fixed amount," said FCC Chairman Tom Wheeler said during Friday's session. "Sharing is key to that."
In order to address the problems and challenges that may arise as spectrum is shared between public and private users, the FCC Order also calls for a public comment period.
Our hope is that this step forward begins to allow more unlicensed technologies that will build on the success of Wi-Fi - allowing residents, neighborhoods, communities, etc., to build high capacity wireless networks. Wi-Fi works well within the home but this spectrum could be used to create similar high capacity networks in neighborhoods.
