Viavi Solutions announced support for verifying the existence of any interference between 5G communications networks and radar altimeters used in the aviation industry, based on its history of testing both wireless and avionics equipment for communication service providers, airlines, military branches and equipment manufacturers worldwide.
Any potential interference would occur in a very narrow band of radio frequency, one that is technically not even part of the C-band (3.7-3.98 GHz) being utilized by communication service providers. Radar altimeter (RADALT) systems use the 4.2-4.4 GHz band. However, there is potential for interference from the edges of these bands, which can be mitigated by testing and adjusting both 5G networks and RADALT systems prior to live deployment.
