Keysight Highlights 280 Gbps Sub-THz Breakthrough for Future 6G Networks
Keysight Technologies (NYSE: KEYS), NTT and NTT Innovative Devices have achieved a record 280 Gbps wireless data rate using sub-terahertz technology, demonstrating the potential for ultra-high-speed wireless backhaul in future 6G networks.
The test operated in the J-band around 220–325 GHz and used a new wideband amplifier based on Indium Phosphide technology. The amplifier enabled substantially higher signal power, while Keysight’s test equipment generated and analyzed 35 GBaud 256-QAM signals to reach the 280 Gbps throughput.
Keysight also used advanced digital predistortion technology to compensate for signal distortion at high frequencies and power levels, improving signal integrity. The achievement addresses key technical challenges associated with moving wireless communications beyond 100 Gbps.
The technology could become increasingly important as 5G and eventually 6G networks require higher-capacity connections between base stations. Sub-THz wireless backhaul could complement fiber, particularly in dense urban areas and locations where installing fiber infrastructure is expensive or difficult.
