Agencies Held Briefing Last Month on 5.9 GHz Sharing, as FCC PN or Similar To Come

Various government agencies held a long-expected briefing (see 1510130059) on the 5.9 GHz band March 23, attended by the Alliance of Automobile Manufacturers, Association of Global Automakers, Cisco, Denso and other organizations and companies, said a filing posted Friday. The FCC is examining sharing of the 5.9 GHz spectrum between Wi-Fi and dedicated short-range communications service (DSRC) systems aimed at preventing road accidents (see 1602050048). The FCC, National Highway Traffic Safety Administration and NTIA were also at the meeting, the filing said. “The Alliance, Global, DENSO, and Cisco reiterated their belief, expressed numerous times in this proceeding, that interference-free sharing between primary DSRC and unlicensed operations in the 5.9 GHz band may be possible, and explained that the four parties continue to work together to develop an industry-led sharing solution,” the filing by the four said. “The four parties also indicated that significant investment by the automotive industry and the Department of Transportation has already been made in reliance on the Commission’s existing 5.9 GHz DSRC rules and the guarantee that all DSRC applications will be protected from interference.” The filing said the FCC clarified it intends to issue a public notice “or similar instrument” that will “refresh the record on the current state of development of 5.9 GHz DSRC technology, invite the submission of detailed unlicensed 5.9 GHz device sharing proposals, and facilitate additional prototype and field testing to ensure appropriate interference-avoidance and spectrum rights allocation in the 5.9 GHz band.” The four offered questions they believe the FCC should ask in a PN, mostly on the technical aspects of sharing. The filing was in docket 13-49.
