The Commission is reviewing potential sharing solutions between proposed Unlicensed National Information Infrastructure (U-NII) devices and Dedicated Short Range Communications (DSRC) operations in the 5.850-5.925 GHz (U-NII-4) band in ET Docket No. 13-49.
U-NII devices provide short-range, high-speed unlicensed wireless connections in the 5 GHz band for, among other applications, Wi-Fi-enabled radio local networks, cordless telephones, and fixed outdoor broadband transceivers used by wireless internet providers.
DSRC uses short-range wireless communication links to facilitate information transfer between appropriately-equipped vehicles and appropriately-equipped roadside systems (“vehicle to infrastructure” or “V2I”) and between appropriately-equipped vehicles (“vehicle to vehicle” or “V2V”).
The Commission is working with the Department of Transportation (DoT), and the automotive and communications industries to evaluate potential sharing techniques. On June 1, 2016 the Commission issued a public notice to refresh the record in the pending proceeding and described a three-phase test plan.
October 29, 2018 – Dedicated Short Range Communications (DSRC) Phase One Testing
OET is performing a study on U-NII-4 prototype devices that have been submitted to demonstrate potential sharing solutions between the proposed U-NII devices and Dedicated Short Range Communications (DSRC) operations in the 5850-5925 MHz (U-NII-4) frequency band. The OET Laboratory Division just concluded Phase One of the tests in a laboratory setting. The test results provide a baseline data for performing analysis of additional operational scenarios and other “real-world” empirical tests as part of the future phases of the coexistence test effort

October 7, 2016 – DSRC and U-NII-4 Prototype Device Testing Open House
OET will hold a DSRC Test Plan Open House on October 21, 2016 at its Laboratory to review the Phase I testing. The Open House will take place from 10 a.m. to Noon. The FCC Laboratory is located at 7435 Oakland Mills Rd., Columbia, Maryland 21046 (telephone (301) 362-3000). The Open House will be open to all interested parties. However, due to space limitations the number of attendees may be limited. Space has been reserved for each of the parties submitting prototype test samples. Attendance by other parties will be on first-come, first-served basis. Parties desiring to attend must register no later than October 17, 2016 by providing their names and organizations by telephone or e-mail to Reza Biazaran at (301) 362-3052 or by e-mail at Reza.Biazaran@fcc.gov.
