More specifically 5G is a protocol and various governing bodies release which parts of the spectrum can be used for 5G in their oversight regions. I'm a bit rusty on which bands are used where but I believe in Europe the band in question was allowed to use up to to 3.8ghz for 5G while the US allowed up to 4.2ghz
5G itself will operate and perform differently (speed, signal decay, material penetration) depending on which part of the spectrum it's using

The other issues are the power permitted is lower in Europe, and around airports network operators installed directional transmitters to keep the signals away from the runways. Not so in the US.

4-holers are generally dead though. Very inefficient compared to much newer gen 787 and A350.

JAL, ANA and EK all announce resumption of 777 service from the US after FAA notice.

Hoping this bodes well for my SFO-LHR flight 20/2.

It’s a USA issue only.

TBH, this is only the tip of a very big looming iceberg of a problem, where commercial interests of one sector impinge upon those of another. The US recently sold off frequencies around 24 GHz that will affect satellite observations that go into weather forecasts (which of course are also used by the airlines). The Chinese are already experimenting with 7G (with presumably 6G somewhere in between).

Does anybody have any idea how long this 5G issue will last? What are the chances of further disruptions down the line? From the agreement reached yesterday it seems the FAA and the telecom companies have just kicked the can down the road again...
