Just...why is this 5th of January such an important date ?
The popular OOKLA internet speed testing site shows lots and lots of commercially available 5G stations around the world, and also close to airports, like JFK.
So, the 5G horse is out of the stable - or is it ??

To clarify the issue once again, there is nothing magic about 5G transmissions that threatens aviation.
5G cellular been operating safely for a couple of years or more in many countries, as shown in the map you linked. Virtually all 5G cellular currently operates in existing frequency bands. I'm using 5G to post this message, on a 2.6 GHz band network.
The potential problem is that cellular systems are now being licensed in a new frequency band between 3.6 and 4.0 GHz - the so-called C band. The exact frequencies vary according to individual country regulations. It is this frequency band which is at issue, and any modulation method in this band whether 2G 3G 4G 5G might possibly be a problem for aircraft radars that respond in this band.
Can we please not conflate 5G with C band. This only confuses the issue, as you have demonstrated.
