The Federal Aviation Administration (FAA) has agreed to allow AT&T and Verizon to activate additional 5G service towers around the country, reports CBS News. The collaboration follows delays launching the new technology as airline officials warned that it could cause disruption to travel without limiting services around US airports. The FAA said wireless companies have "provided more precise data about the exact location of wireless transmitters and supported more thorough analysis of how 5G C-band signals interact with sensitive aircraft instruments." The latest data has also led regulators to allow more aircraft to use essential airports safely, the agency said. As of January 28, an estimated 90% of US commercial aircraft have approved radio altimeters, which allows fleet to land in low-visibility areas where 5G services have been deployed, according to the administration. The FAA said it will continue to work with the aviation community to ensure aircraft can safely operate in 5G-activated areas.
