wenn sie das mit der Latenzeit noch hinkriegen, dann wird das die Zukunft sein.
3G wurde laut der untenstehenden page in IMT-2000 (International Mobile Telecommunications 2000...was auch immer das ist bzw. war) standardisiert.
4G ...wobei der Term 4G eigentlich noch nicht wirklich genau definiert ist:
"Systems beyond IMT-2000, for which there may be a need for a new wireless access technology to be developed around the year 2010, capable of supporting high data rates with high mobility. High mobility here covers high speed on highways or fast trains (60 kilometers/hour to 250 km/h, or more). It is predicted that potential new radio interfaces will need to support data rates of up to approximately 100 Mbps (megabits per second) for high mobility such as mobile access and up to approximately 1 Gbps (gigabit per second) for low mobility such as nomadic/local wireless access, by around the year 2010."
