OOBE Limits More Than Enough ITS Protection in 5.9 GHz, Wi-Fi Interests Say
The stringent out-of-band emissions (OOBE) limit proposed by Wi-Fi interests on unlicensed use of 5.9 GHz (see 2008030022) would more than protect adjacent intelligent transportation systems (ITS), but still follow IEEE standards, Wi-Fi advocates told FCC Office of Engineering and…

Technology staff, according to a docket 19-138 ex parte posting Wednesday. The filing said technical analyses in the record back a more flexible OOBE limit but tying the technical rules to IEEE standards would be an extra layer of protection to ITS operations while allowing unlicensed devices to operate. And they said duty-cycle analysis by Broadcom and Facebook and the low duty cycle expected given that any in-vehicle Wi-Fi would be supported by cellular backhaul show that in-vehicle use of unlicensed devices pose "negligible" risks of interference. Meeting with the FCC were CableLabs, Charter Communications, Comcast, Broadcom, Facebook and NCTA.
