Terahertz Wireless

Could help cover the planet with internet that’s 10X faster than 5G.

A new transmitter has been developed by the National Institute of Information and Communications Technology, that can achieve data transfer speeds 10 times faster than 5G.

A partnership between Hiroshima University, the National Institute of Information and Communications Technology, and Panasonic. Has developed a new terahertz (THz) transmitter that could boost the strength of satellite powered internet, providing speeds that exceed 100 gigabits per second (Gbps) on a single channel.

A frequency range of 290-315 GHz is used to transfer data. Which achieved a transfer speed of 105 Gbps, which is at least 10 times faster than next-generation 5G networks.

In the previous year they were using quadrature amplitude modulation (QAM) to transfer data in the 300 GHz band, that only achieved six times higher speeds at that point with the THz transmitter. With the new terahertz transmitter they have been able to transfer a DVD full of content in a fraction of a second.

As of now the frequency band used in the tests isn’t currently used, but at the World Radiocommunication Conference in 2019, the range is set to be discussed. And some interseting possibilities for the future could come about.

When we talk about wireless data rates we usually talk in megabits per second or gigabits per second. But now we are talking about terabits per second using a plain simple single communication channel.

Fiber optics realized ultrahigh speed wired links, and wireless links have been left behind. Terahertz could offer ultrahigh speed links to satellites as well, which can only be wireless.

If a satellite provider wireless internet used the new transmitter it could boost speeds on the ground and also for airplanes in flight.

SpaceX, which is planning to launch some 4,000 satellites to provide home broadband. If they were to use this technology, we could see global internet access with unbelievable speeds.

The THz wireless technology could also provide the high data rate of fiber optics, with the low latency offered by microwave lengths.
