FEDERAL COMMUNICATIONS COMMISSION WASHINGTON OFFICE OF THE CHAIRMAN November 4, 2019 The Honorable Bob Latta U.S. House of Representatives 2448 Raybum House Office Building Washington, DC 20515 Dear Congressman Latta: Thank you for your letter expressing support for the Federal Communications Commission refreshing the record in the 5.9 GHz proceeding. To say the least, substantial time has passed since the FCC initially granted Dedicated Short Range Communications (DSRC) vehicle-to-vehicle technology experimentation in this band in the 1990s. DSRC has made little progress since then its deployment is meager at best, only one automaker currently supports it, and no major models are scheduled to use DSRC in the near future. Indeed, the rest have jettisoned the failed technology of DSRC, focusing their efforts on the development of cellular vehicle-to-everything (C-V2X) automotive safety technologies. Meanwhile, consumer demand for applications and services that rely on unlicensed spectrum has exploded. The technological standard forunlicensed use of the 5.9 GHz band, called 802.1lac, has long been established. The band below it is afready used for Wi-Fi, and the Commission is exploring unlicensed opportunities in the 6 GHz band above it. It is long past time for rethinking the highest-valued use of this public resource. That is why I support a comprehensive conversation about how to proceed in the context of a notice of proposed rulemaking. Thank you for sharing your views on this matter. Please let me know if I can be of any further assistance. Sincerely, (J
