FCC Suggests Alternative Spectrum for Wireless Microphones
TVTechnology.com reports that the same day the FCC released its Notice of Proposed Rulemaking (NPRM) regarding unlicensed and wireless microphone operations in the 600 MHz band, it also released an NPRM on “promoting spectrum access for wireless microphone operations.” The NPRM asks many questions but provides few answers. It gives some insight into the options the commission is considering for wireless microphones.
One solution would be to encourage wireless microphone use in available spectrum outside the TV bands. These include existing licensed broadcast auxiliary service spectrum at 26 MHz, 161 MHz, 450/455 MHz, and 950 MHz, where broadcasters currently use wireless microphone and IFB systems as well as certain licensed Part 90 Business Radio spectrum. The 6875-7125 MHz BAS microwave band appears in one list. Several bands available for unlicensed use are also discussed. These include the 88-108 MHz FM band, 902-928 MHz band, the 2.4 GHz and 5 GHz bands commonly used for Wi-Fi, the 1920-1930 MHz unlicensed PCS band and ultrawide band systems using 3.1 to 10.6 GHz. Other bands include 1435-1524 MHz, where wireless microphone operations have been allowed on a temporary basis under special temporary authority for certain events, and the 3.5 GHz band.
