there is no true of false 4G. G simply means generation.
1G can be used for voice transmission. 2G realizes data transmission over essentially the same network.
3G has whole new systems dedicated to data transmission, independent and well integrated with the Internet.
4G mainly improves the infrastructure of the 3G standards, such as multiple antennas in devices, better error control, and link ups to wired networks...
and at each step the ITU defines and sets standards..
