5G systems are not yet universally available, but 6G technologies are already in development.
Main
Now 5G communication operates at frequencies up to about40 GHz, but 6G will push them beyond 100 GHz, leveraging the as-yet untapped terahertz spectrum. The new technology will also boost bandwidth, which is around 400 MHz for 5G.
For the new test, researchers from Samsung and the University of California, Santa Barbara, demonstrated a system with a frequency of 140 GHz and a bandwidth of 2 GHz.At the same time, they managed to transmit data at a speed of 6.2 Gbit/s over a distance of 15 m.In comparison, the speed record for 5G was 5.23 Gbps.
The system consists of a 16-channel phased array transmitter, a receiver module, and a baseband unit that processes the signals and helps direct the beam to the receiver.
6G is not expected to hit the market until 2030.
The team showcased the new 6G device at the IEEE 2021 International Communications Conference.
