In a recent decision, the Federal Communications Commission (FCC) chose not to adopt the rules it proposed in 2015 to reserve a vacant channel in the UHF Television Band for use by white space devices and wireless microphones. The FCC found that these rules were no longer necessary due to changes in the TV spectrum landscape following the Incentive Auction and actions the FCC has taken since 2015 to support these technologies. They believe continuing with existing measures is more effective and avoids burdening broadcasters with additional requirements. Consequently, the FCC has ended the proceeding.
Simple Explanation
The FCC decided not to make a special channel for certain gadgets and microphones because they already made other changes that help, and adding more rules would just make it harder for TV stations.
