Qualcomm, Nokia, Samsung clash with Wi-Fi Alliance over 5.9 GHz for C-V2X

Qualcomm, Nokia and Samsung are among those supporting a request by the 5G Automotive Association (5GAA) for permission to conduct Cellular Vehicle-to-Everything (C-V2X) in the upper portion of the 5.9 GHz band, something the Wi-Fi Alliance and other groups want the FCC to reject.

The 5GAA filed a waiver request back in November saying the FCC’s current rules for the 5.9 GHz band—adopted well before the development of C-V2X—restrict intelligent transportation system (ITS) operations to those that use the dedicated short-range communications (DSRC) standard…

Those in support of the waiver say C-V2X can be a viable and in some cases preferable technology to DSRC, while those who oppose the 5GAA’s move say it threatens not only DSRC but also Wi-Fi’s ability to make wider use of the 5 GHz band. A separate evaluation of the 5.9 GHz band is currently underway at the FCC.
