RS Access: Updated Engineering Shows 5G Can Share 12 GHz Band
RS Access submitted a new engineering study on the use of the 12 GHz band for 5G to the FCC, which it said refuted interference concerns raised by SpaceX on an engineering analysis submitted a year ago (see 2109280059). RKF…

Engineering Solutions, which wrote the earlier report, performed the study. “RKF has considered comments addressing its May 2021 report and, in a study filed today, has again found that terrestrial 5G wireless broadband in the 12.2-12.7 GHz band can readily coexist with non-geostationary orbit (NGSO) fixed satellite service deployments, which use 10.7-12.7 GHz for downlink,” said a filing posted Friday in docket 20-443. “The probability of any harmful interference to NGSO operations is no greater than 0.15 … and the probability of any impact on actual users is likely to be substantially less,” the filing said. SpaceX didn’t comment Friday. The FCC is considering revamped rules for the band, with the Office of Engineering and Technology still evaluating the engineering analysis (see 2203210056).
