Use of Radio Frequencies Above 40 GHz for New Radio Applications

By this Third Report and Order (R&O) the Commission amends the rules to: provide amateur and amateur-satellite operators co-primary status in the 77.5-78 GHz frequency band to ensure that future amateur station access to spectrum near 77 GHz is maintained without the threat of preemption by higher priority services; restrict amateur and amateur-satellite operations in the 76-77 GHz frequency band to ensure against potential interference to vehicle radar systems that we expect will operate in this band; adopt a spectrum etiquette for unlicensed devices operating in the 59-64 GHz frequency band to provide a spectrum etiquette that maximizes the number of users and minimizes the potential for interference in the 59-64 GHz band; and adopt spurious emission limits for unlicensed equipment operating in the 76-77 GHz frequency band to provide protection to radio astronomy operations in the 217-231 GHz band.
