In a second  development that  relates to Wi-Fi, Senators Marco  Rubio (R-FL) and  Cory Booker (D-NJ) introduced legislation last Friday that would designate a portion of the 5 GHz band currently allocated for intelligent transportation systems for unlicensed Wi-Fi use. Titled as the Wi-Fi Innovation Act (S. 2505), the bill follows the Wireless Innovation Act as Rubio’s second attempt this month at expanding the availability of wireless spectrum resources. (Introduced on June 12, the Wireless Innovation Act directs the National Telecommunications and Information Administration to free up federal government spectrum for commercial wireless use.) Targeting the 5.850 GHz-5.925 GHz band, the measure requires the FCC to conduct tests and take other steps to allocate those channels for Wi-Fi use if it can be shown that Wi-Fi use won’t interfere with incumbent operations. As a first step, the FCC would be required within three months of the bill’s enactment to solicit comments on “interference mitigation techniques and technologies that would accommodate both incumbent licensees . . . and widespread commercial unlicensed operations in the 5850-5925 MHz band.” Within six months, the FCC would be required to publish a test plan and proposed timeline for testing that would have to be completed within 15 months. After publishing a summary of the test results, the FCC would be required to modify its rules within 18 months if the agency determines that unlicensed usage of the band can be accomplished without the risk of harmful interference to incumbents. Among other things, the FCC would also be required to conduct a study to assess Wi-Fi deployment to low-income communities and “the barriers preventing deployment of wireless broadband in those neighborhoods.” Pointing to the “clear and growing demand for increased availability of spectrum” for Wi-Fi, Booker told reporters he joined forces with Rubio “because we want to see this valuable resource made available for further use by the public.” As CTIA President  Meredith Atwell Baker welcomed Rubio and  Booker’s “leadership  in pushing to  make additional spectrum available for unlicensed use,” a spokesman for the Intelligent Transportation Society of America struck a cautious tone in voicing support for “[this] collaborative effort” which “should be allowed to proceed without arbitrary deadlines, restrictive parameters or political pressure that could influence the outcome.”
