Apparently there's a 5G already, probably in South Korea or in a lab in Milton Keynes, and Qualcomm's got a chipset that can tune into it -- the Snapdragon X50.
It's the biggest and most exciting thing at the company's 4G/5G Summit in Hong Kong, where it demonstrated a mobile modem for use by manufacturers and networks in their technology trials with the ability to download data at bonkers download speeds of up to 5Gbps. That must be why it's called 5G.
It does this via the 28 GHz millimeter wave (mmWave) band of radio space, somehow, making videos of people falling over into small bits of data that fly through the air and reassemble on your too-big telephone.
Also wary that 5G is only a guesstimation of possible technologies at the moment, Qualcomm says the X50 is also compatible with Gigabit Class LTE -- a sort of 4.5G it hopes might pave the way for faster networks before the boffins of the world decide what form the actual 5G networks should take.
