3G

Third generation (3G) is the technology that enables high-speed data transfer. Data can be transmitted up to 50 times faster per minute compared with non-3G data speeds.

4G

Fourth generation (4G) technology allows ultra-high-speed data transfer. In optimal conditions, 4G can enable data to be transmitted 10 times faster than via 3G.

5G

Fifth generation (5G) is the latest technology in mobile data and is set to bring even faster data transmission up to 100 times faster than 4G meaning streaming and downloads will take a fraction of the time. 5G has already arrived in some parts of the world and is set to begin rolling out in the UK from late 2019.

Asymmetric Digital Subscriber Line
