Scientists have revealed that record breaking speeds were achieved during tests of 5G data connections.
The researchers from the University of Surrey managed one terabyte per second - thousands of times faster than current data connections.
The head of the 5G Innovation Centre (5GIC) said he hoped to demonstrate the technology to the public in 2018 and Ofcom said 5G would be made available to the public by 2020.
At 1Tbps it would be theoretically possible to download a file 100 times the size of a feature film in about three seconds. The speed is more than 65,000 times faster than the average 4G download speeds.
5GIC director Prof Rahim Tafazoli said: "We have developed 10 more breakthrough technologies and one of them means we can exceed 1Tbps wirelessly. This is the same capacity as fibre optics but we are doing it wirelessly."
He also said he wanted to carry out more tests around the university's campus before going public.
He added: "We want to be the first in the world to show such high speeds."
Ofcom has been extremely supportive of efforts to get 5G to the public and last month it called for input from the industry on how to go about it.
The regulator said it expected 5G mobile to be capable of delivering between 10 and 50Gbps, compared with the 4G average download speed of 15 megabits per second.
Chief executive at Ofcom Steve Unger said: "5G must deliver a further step change in the capacity of wireless networks, over and above that currently being delivered by 4G."
However, Tafazoli believes there are hurdles to overcome before 5G is ready.
He said: "An important aspect of 5G is how it will support applications in the future. We don't know what applications will be in use by 2020, or 2030 or 2040 for that matter, but we know they will be highly sensitive to latency.
"We need to bring end-to-end latency down to below one millisecond so that it can enable new technologies and applications that would just not be possible with 4G."
