Researchers at the University of Surrey's 5G Innovation Centre (5GIC) managed speeds of one terabit per second (Tbps) - thousands of times faster than current data connections.
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 average 4G download speeds, 'BBC News' reported.
Previously, Samsung Electronics has set 5G speed record at 7.5Gbps, which is less than 1 per cent of the Surrey team's speed.
The tests were conducted in lab conditions over a distance of 100m, according to news website V3.
It remains to be seen whether it will be possible to replicate the speeds in real-world conditions but Tafazolli hopes to demonstrate the technology to the public in 2018.
