Assessment of potential interference between FM broadcasting stations operating in the band around 87-108 MHz and aeronautical VDL Mode 4 systems in the band 112-117.975 MHz operating in the AM(R)S
This Report addresses compatibility issues between FM broadcasting stations and the VDL Mode 4 system. This Report follows closely the principles described in Recommendation ITU-R M.1841 because the FM immunity criteria that have been developed for VDL Mode 4 are identical to those for GBAS.
