Nine out of ten of America’s commercial aircraft can land in low visibility using radio altimeters at US airports that have nearby 5G C-band masts, the country’s aviation watchdog said this week.<\/p>\n

There is a concern that signals at the top of the 5G C-band, namely 3.98GHz, could bleed into the 4.2-4.4GHz band used by airliners’ radio altimeters, which are quite handy when visibility is poor. The presence of 5G-C masts could thus affect the ability of aircraft to land safely in sub-optimal weather, it’s been claimed.<\/p>\n

AT&T and Verizon this month agreed to partially stall<\/a> the roll out of 5G-C masts in the US \u2013 deploying the tech away from airports \u2013 while the Federal Aviation Administration (FAA) looked into matter. Specifically, the watchdog has been checking the radio altimeters on commercial aircraft to see if the equipment works as expected within range of 5G-C communications.<\/p>\n
