5G is the next step in mobile connectivity, promising significantly faster data uploads and downloads than current 4G connections. Trials of the technology have reached speeds as high as 10 Gbps per second, though they are unlikely to be quite that fast when 5G services launch in the next few years. Still, connections are expected to be quick enough to download a high definition movie in a matter of seconds.
The term 5G itself refers to the ‘fifth generation’ of mobile data. 1G allowed calls, 2G added text messages and MMS, 3G added video calls and internet access and 4G brought broadband quality connections.
The speed of 5G is forecast to enable many systems in cities to talk to each other at once – such as transport, traffic and utility services. It will be a major part in making the Internet of Things a reality.
