Samsung Electronics teamed up with the University of California Santa Barbara (UCSB) to demonstrate a prototype 6G wireless communication system using the terahertz frequency range.
At a recent workshop held at the IEEE International Communications Conference (ICC 2021), a joint research team presented 140 GHz wireless communications using a digital beamforming solution.
As noted by Samsung, the development of this prototype is an important milestone in the study of the potential of the THz band for 6G wireless communication. The use of this band provides the broadest spectrum with dozens of possible broadband channels in gigahertz bands, meeting 6G requirements for data rates in terabits per second.
Samsung emphasizes that peak data rates can be 50 times faster than 5G, and radio latency will be reduced to one tenth.
The prototype of the system shown consists of 16-channel transmitter and receiver modules with a phased array, controlled by CMOS RFIC chips, and a main unit that generates signals with a 2 GHz bandwidth and fast adaptive beamforming. In pilot tests, the prototype of the system achieved a throughput of 6.2 Gbps at a distance of 15 meters with adaptive terahertz beam steering.
