With Replies Due, 5GAA Says It Filed Flawed Data on 5.9 GHz Tests

Replies are due Tuesday on a waiver request by the 5G Automotive Association to deploy cellular vehicle-to-everything technology (C-V2X) in a 20 MHz channel of the 5.9 GHz band. 5GAA told the FCC it provided incorrect information in a report in support of the waiver, in a filing posted Monday in docket 18-357. “5GAA’s petition for waiver, indicates that [dedicated short range communications] devices used in 5GAA’s testing had employed receive antenna diversity,” the group said: “In fact,” the devices “did not utilize receive antenna diversity. As a result, 5GAA is expanding its testing to collect DSRC data that reflects the use of receive antenna diversity, and plans to file such expanded data in this docket in near term.” The group said “notably, this does not change the C-V2X test results” and “we are confident that this does not change the report’s ultimate conclusion, which is that C-V2X technology substantially outperforms DSRC technology.” The waiver got mixed reviews in initial comments (see 1902110007). Commissioners Mike O’Rielly and Jessica Rosenworcel said Feb. 14 they support instead a broad NPRM (see 1902140057). In a comment posted Monday, the Truck and Engine Manufacturers Association said the FCC should reject the waiver. “To avoid disrupting the DSRC deployments that are based on the exclusive use of the 5.9 GHz band, FCC must conduct rigorous testing, including real-world testing, to validate that C-V2X signals will not interfere with DSRC messages,” the group said.
