a In Mainland China, four licensed frequency bands are allocated for 5G wireless communications: > 3.3 - 3.6 GHz (= bandwidth 300 MHz) > 4.8 - 5 GHz (= bandwidth 200 MHz) > 24.5 - 27.5 GHz (= bandwidth 3 GHz) > 37.5 - 42.5 GHz (→ bandwidth 5 GHz) Two of them are in the millimetre-wave frequency range. Do you see why using the millimetre-wave frequency? If a wireless channel for video transmission needs 6 MHz, how many channels can there be in the millimetre-wave 5G technologies?
