Objections Raised to Proposed Liberalization of 6 GHz Rules
Among other objections to an FCC proposal to expand the parts of the 6 GHz band where very-low power (VLP) devices can operate without coordination, and make other changes to the rules (see 2404290035), NAB stressed the importance of protecting…

broadcasters' use of the band for electronic news-gathering. “Allowing unrestrained VLP operation by millions -- or even billions -- of unlicensed devices amounts to letting the metaphorical ‘genie out of the bottle,’ potentially creating a radio frequency interference environment that cannot be controlled,” NAB said. Sirius XM said its satellite digital audio radio service business “cannot operate without reliable access to the 7.025-7.075 GHz band to uplink programming for delivery to listeners and control its spacecraft.” Proponents haven’t demonstrated a need to expand the bands where VLP devices can operate, Sirius XM said: “The public interest in protecting service to tens of millions of satellite radios -- both subscribed and unsubscribed -- far outweighs any speculative benefit from adding marginally to the spectrum that can be used for outdoor VLP devices.” The Fixed Wireless Communications Coalition said the record “remains insufficient to move forward with the Commission’s proposals at this time.” Comments in favor of changing the rules “were either non-substantive or rehashed information previously submitted to the record,” the group said. The 5G Automotive Alliance said out-of-band emissions limits of -37 dBm/MH are needed to protect cellular vehicle-to-everything operations in the 5.9 GHz band. “The record in this proceeding demonstrates commenters’ well-founded concerns about VLP devices interfering with C-V2X operations and the possible dire consequences of such interference,” the alliance said. Comments were posted this week in docket 18-295.
