Researchers in Japan use terahertz frequencies to transmit data at 3 Gbps

Researchers from the Tokyo Institute of Technology have made a very interesting breakthrough that could have serious implications for wireless high-speed data networks. The researchers have developed a new wireless transmission system that works using a frequency that is unregulated by any country or standards organization in the world. The system the researchers developed works in the range of 300 GHz to 3 THz.

Those frequencies are in the far infrared range of the spectrum. Using the technology the researchers have been able to transmit data at 3 Gbps and in theory transmission at up to 100 Gbps should be possible. The system has been dubbed T-Ray and is said to be similar to WiGig. That means it needs line of sight and can transmit large amounts of data at one time.

The T-Ray system is limited to a range of only 1 to 3 m without significant power boosting. However, with power boosting it could match or surpass the range of WiGig. The tiny transceiver in the photo above next to the coin was the key development that led to the research. The transceiver was made by a Japanese semiconductor company called Rohm. The first application for this technology is likely to be server farms because it has high throughput and low data latency.
