AVSI has continued its engagement with aviation industry members and regulators to provide leadership and data that supports development of solutions addressing the risk posed by potential interference from new 5G signals. An earlier post described how the AFE 76s2 Project Participants agreed that it was in the best interest of aviation safety to work with all stakeholders to resolve outstanding concerns in order to minimize impact to aviation operations while supporting the least restrictive rollout of 5G. To this end, the AFE 76s2 team has published a report that catalogs empirical interference tolerance thresholds measured by both AVSI and individually by RA manufacturers.
The report is structured in three volumes:
- Volume I contains the introduction, test procedures, and test results from out-of-band interference representative of 5G fundamental signals. Volume I can be downloaded here: AVSI AFE 76s2 Project Report – Volume I
- Volume II contains the test results from in-band interference representative of 5G spurious signals and identifies changes to the test conditions and analysis for spurious tests. Volume II can be downloaded here: AVSI AFE 76s2 Project Report – Volume II
- Volume III contains additional manufacturer-provided test results. This third and final volume has been published and is now available for download here: AVSI AFE 76s2 Project Report – Volume III
Based at Texas A&M University, AVSI is an aerospace industry research cooperative that facilitates collaborative research and technology projects for its members. This project (AFE 76s2) included representatives from Airbus, Aviation Spectrum Resources Inc. (ASRI), Collins Aerospace, Embraer, Federal Aviation Administration (FAA), Garmin, Honeywell, the International Air Transport Association (IATA), Lufthansa Technik, National Aeronautics and Space Administration (NASA), Texas A&M University, Safran, and Thales. Project Participants contributed the subject matter expertise necessary to complete this project, including radar altimeter design engineers, aircraft systems integration experts, and aviation spectrum regulators.
