Super-fast mobile streaming, 5G, could be just around the corner.
Network providers around the world are already gearing up to test 5G networks throughout 2018, with the first 5G-ready smartphones expected to be released early next year.
If everything goes to plan, the idea is that 5G will bring us broadband-equivalent download speeds over mobile networks. That would mean no more waiting ages for videos to buffer or web pages to load and make it easier for things like driverless cars to transfer vast amounts of data really quickly. If you can get a mobile signal, of course.
But don’t start thinking about trading-in your old-fashioned 4G device just yet – it’s still not clear which manufacturers and networks will upgrade to 5G first, or how long it’ll take. In the meantime, here’s everything you need to know about the slow shift to 5G.
What is different about 5G?
When they arrive, 5G networks will be able to handle more data and connect more devices simultaneously and do this all at much faster speeds than is possible using existing technology. While current 4G download speeds max out at around 50 megabits per second – and in reality usually have speeds much lower than this – 5G networks have been demonstrated that run at up more than 100 times that speed.
Why is it so much faster than 4G?
All our existing mobile networks use radio waves, but 5G is faster because it uses bits of the electromagnetic spectrum that aren’t currently being used by other kinds of network. New developments in receiver and transmitter technology allow 5G networks to communicate using very high and very low-frequency waves which, until recently, was impossible using existing technology.
When will we get 5G?
Right now, there’s not a single 5G-ready smartphone on the market, but Samsung, LG, Sony, HTC and 14 other phone manufacturers have already announced that they’re working with the chip manufacturer Qualcomm to bring out 5G-ready devices in 2019.
What’s taking so long?
Things in the mobile network world tend to move at a sub-glacial pace. The problem is that shifting to a new network standard requires a whole bunch of people, from the chip and handset manufacturers who will be making the technology to the network providers who will be making sure it runs smoothly, to agree on a way that the technology will be delivered.
