Given that the whole wi-fi systems on planes are all very old unless the planes have Starlink, I wouldn't assume it's even remotely new.

Note: Not that it wouldn't be possible to have even SOTA wi-fi 7 and still use the same old legacy satellite uplink WAN connection, it's just that I can't imagine what airline would consider that "upgrade" worth taking airplanes out of service for to perform, when it wouldn't do jack to increase the speeds people would get.
