5G network

5G, or fifth-generation mobile communication technology, is expected to be first put into commercial use by 2020, according to a timetable mapped out by the International Telecommunication Union (ITU).

The new generation of networks is expected to have peak data transfer speed of 20 gigabits per second, almost 100 times faster than the current 4G networks.
