And last year, the FCC proposed changing how frequencies in the 6 GHz range can be used, hoping to open some licensed space up for public use - or possibly sharing it. Last month, the FCC voted to make spectrum above 95 GHz available for unlicensed use, Grace said. "The FCC has been aggressively working to push more unlicensed spectrum into the commercial marketplace," Grace said. "That's illegal."īut for years, there's been a push to open up more frequencies for public use, said Neil Grace, a spokesman for the FCC, in an email. "You're not allowed to transmit in AT&T's band," Rabaey said. But there are several other frequencies that are licensed, he said, meaning they're owned by private companies. That frequency range - along with a handful of others - are considered "unlicensed bands," Rabaey said, meaning anyone is allowed to broadcast on them without FCC approval. That means your headphones are competing with most other wireless devices, including Wi-Fi routers, cordless phones and even odd appliances like microwave ovens and cheaply made power adapters. All wireless gadgets compete on a limited amount of available space in the available spectrum, Rabaey said.Īnd your Bluetooth devices operate on just a fraction of that spectrum, he said, between 2.4 GHz and 2.8 GHz.
