Next-Generation Sensors Enable Data Transmission at 640 Gbps

Scientists from Japan’s National Institute of Information and Communications Technology and Tokyo Institute of Technology have unveiled a new set of D-band transceiver chips. These components support a bandwidth of 56 GHz, enabling wireless data transmission at speeds up to 640 Gbps.

To meet the growing demand for traffic, wireless systems are increasingly using higher frequencies in the millimeter-wave range. Current broadband 5G systems offer speeds up to 10 Gbps, operating in frequency bands between 24-47 GHz. The new systems aim to operate at even higher frequency ranges.

To enhance signal quality, engineers have utilized the D-band spectrum from 110 to 170 GHz. However, such systems are prone to attenuation, making cost-effective transmitters and receivers essential for the global coverage of next-generation wireless setups.

To address this, scientists developed a new set of D-band transmitter chips, manufactured using a 65-nm silicon process. This approach makes the development of these boards more cost-effective for mass production. In their experiments, engineers achieved data transmission at a speed of 200 Gbps over a distance of 36 centimeters. Over a distance of 15 meters, the speed was 120 Gbps, which is 10 to 100 times faster than existing systems.

For American readers, this breakthrough is particularly significant as it highlights the ongoing advancements in wireless communication technology, which could soon lead to unprecedented data transmission speeds, impacting everything from consumer electronics to large-scale data networks.
