What is 5G?
5G is the fifth generation of mobile networks, following on from 2g, 3g, and 4g. But while the move from 3g to 4g was all about speed. 5G is about so much more. Sure 5g is extremely quick, but it's also stable and reliable, with characteristics that will allow it to form the underlying communication network for connected vehicles virtual reality worlds and robotic systems.
How does it work
Like its predecessors, 5g is transmitted via radio waves. It will use some frequencies that are in the 4g range, as well as a higher frequency, called millimeter wave technology. The latter enables the speed and capacity that 5G needs. It can even be sensitive to environmental factors such as rain.
When is it coming
Trials of 5G technology are currently taking place but it's predicted that a fully standardized version will start to reach UK consumers in 2020. When it arrives, it will most likely focus in the urban area first, the government says it will be rolling out 5g nationwide by 2021.
How Fast is it
5G will bring an expected tenfold surge in speeds compared with todays. 4G network. Speed of 5g network will 1GB/sec. Some claimed it could reach 10GB/sec. The benefit of this speed is great.
Will I need a new phone
Yes, but it won't be hard to find one. 5G smartphones, such as the Samsung galaxy s10, one plus 7 may support 5G.
