Problems with 5G transmissions causing serious aviation interference issues have still NOT been resolved (see 1, 2).  Even though the Biden Administration refuses to extend the July 1 deadline for airlines to address this, telecom companies have agreed to play nice.

IATA Welcomes Telcos' Agreement to Extend 5G Mitigations but More is Needed

Geneva – The International Air Transport Association (IATA) welcomed the agreement by AT&T Services, T-Mobile, UScellular, and Verizon to extend until January 1,  2028 the voluntary mitigation measures for 5G C-band transmissions at 188 US airports. These mitigation measures, which were put in place in January 2022, concurrent with the rollout of 5G C-band operations at or near US airports, include lowering the power of 5G transmissions and had been set to expire July 1, 2023. However, while the agreement is a welcome stop-gap development, it is by no means a solution. The underlying safety and economic issues around 5G C-band deployments by telecommunications services providers (telcos) have only been kicked down the road.
