Disagreements Remain on Any 5.9 GHz Rethink

was adopted last year “coupled with significant concerns about the Commission’s decision raised by stakeholders … both necessitate reconsideration of the decision,” AAI said: Oppositions to its petition “mischaracterize the amount of spectrum needed for life-saving [vehicle-to-everything] applications that can support automated vehicle technologies.” 5GAA claimed “broad support for the one issue on which 5GAA seeks partial reconsideration,” that the FCC should provide cellular-V2X an additional 20 dB of protection from out-of-band emissions in the Wi-Fi part of the band. “Opponents of this position largely contest the requested relief on procedural grounds in the hope of persuading the Commission to ignore 5GAA’s well-founded concerns,” the group said. T-Mobile said 5GAA raises questions worth considering. “Responses to the 5GAA Petition highlight that there are serious questions regarding whether the OOBE limits adopted … are appropriate,” the carrier said: “Whatever emissions limits the Commission adopts, T-Mobile strongly agrees that C-V2X operations must be protected from harmful interference by unlicensed devices.” NCTA targeted supporters of the 5GAA petition: “If the Commission were to undo its Order and adopt the 5GAA OOBE mask, it would delay the long-awaited benefits of gigabit-Wi-Fi." The AAI petition “should be granted because the Commission did not properly evaluate record evidence,” said Continental Automotive Systems. The part of the order reallocating most of the band for Wi-Fi is “unlawfully arbitrary and capricious,” the company said.
