Canada Updates 3900 Mhz Band Rules to Protect Radio Altimeters
Innovation, Science and Economic Development Canada (ISED) has released new rules establishing a non-competitive local licensing (NCL) framework for the 3900 MHz band. This framework aims to protect radio altimeters operating in the 4200-4400 MHz band through interference mitigation measures. The goal is to balance technological innovation with aviation safety. The new regulations outline specific requirements and guidelines for NCL licensees to ensure responsible spectrum use and minimize potential disruptions to critical aviation systems. This initiative reflects ISED's commitment to effective spectrum management and public safety.
