The transfer of terrahertz wave data has been achieved for the first time by American and French engineers. The achievement will allow even faster wireless data transfer (Wi-Fi) in the future, at unprecedented speeds, up to 100 times greater than today.

Multiplexing is the ability to send multiple signals over a single channel and constitutes a key component of any voice or data communication system. Terahertz are a high-frequency radiation (1 THz equivalent to 1,000 GHz).
For the first time, it has become possible to “marry” multiplexers and terahertz, which can pave the way for the next generation of ultra-high-speed broadband wireless networks.
The researchers, led by Professor Daniel Mittelman of the Brown University of Rhode Island School of Engineering in the United States, published in Nature Communications, managed to stream two high-resolution video videos via a terahertz multiplexer, at the frequencies of 264.7 GHz and 322.5 GHz.
The transmission speed was about 50 gigabits per second, about 100 times faster than today’s fastest wireless networks. Most wireless networks today have speeds of up to 500 megabytes per second.
Existing voice and data networks use microwaves to wirelessly transmit signals. However, as the demand for ever increasing transmission of ever-increasing data increases, microwave networks are now reaching their limits.
Terahertz waves have higher frequencies than microwaves and therefore greater data transmission capability. Experimentation with the terahertz frequencies has just begun and so far many necessary components for communication in THz do not yet exist.
Such a vital component to be developed is a mux / demux system that will allow a cable to carry multiple TV channels or hundreds of users to access a wireless Wi-Fi network in THz . The new study has made the first essential step in this direction.
