In the Matter of
\nUse of the 5.850-5.925 GHz Band<\/p>\n
NOTICE OF PROPOSED RULEMAKING<\/p>\n
The 5.9 GHz band, once expected to support widespread deployment of systems that
\nwould improve efficiency and promote safety within the Nation\u2019s transportation infrastructure, has not
\nlived up to its potential. The promise of ubiquitous vehicle-to-vehicle and vehicle-to-infrastructure
\ncommunications in this band has never materialized, while vehicle manufacturers increasingly are using a
\nmultitude of other radio frequency based and other technologies to deliver tangible safety benefits.<\/p>\n
To ensure that the American public realizes the maximum value from this 75 megahertz
\nof mid-band spectrum, we initiate this Notice of Proposed Rulemaking to assess the 5.9 GHz band rules
\nand propose appropriate changes to ensure the spectrum supports its highest and best use. Recognizing
\nthe current state of vehicular technology and deployment and the evolution of the telecommunications
\nmarket, our \u201cfresh look\u201d approach proposes to continue to dedicate spectrum\u2014the upper 30 megahertz
\nportion of the band\u2014for transportation and vehicle safety purposes, while repurposing the remaining
\nlower 45 megahertz part of the band for unlicensed operations to support high-throughput broadband
\napplications.<\/p>\n
