Currently, 5G communications operate at frequencies up to about 40 GHz, but 6G would push that beyond 100 GHz, tapping into the as-yet-unutilized THz spectrum. The new tech would also give a boost to bandwidth too, which for 5G tops out at around 400 MHz.
For the new test, researchers at Samsung and the University of California, Santa Barbara demonstrated a system with 140 GHz frequency and a bandwidth of 2 GHz. In doing so, they managed to transmit data at 6.2 Gbps over a distance of 15 m (49 ft).
That’s a decent step up from 5G’s speed record of 5.23 Gbps, and even that was with the help of some 4G frequencies in a mostly experimental setup. But still, it’s far short of what 6G could eventually be capable of – data transfer rates of up to 1 Tbps, which is 1,000 Gbps.
The new test may sound exciting, but don’t throw away your fancy new 5G phone just yet – 6G isn’t expected to be commercially available until about 2030.
The team demonstrated the new 6G device at the IEEE International Conference on Communications 2021.
