Wi-Fi speeds will be 100 times faster than they are now.

For the first time, American researchers have been able to send video signals using terahertz waves instead of traditional microwaves. This opens up the possibility of creating ultra-fast Wi-Fi speeds, up to 100 times faster than today.

Microwave networks are struggling to transmit the amount of data that internet users demand.

Terahertz waves are high-frequency radiation that allows data to be transmitted at speeds of 50 gigabits per second. This creates the potential for transmission speeds up to 100 times faster than current wireless networks, which reach a maximum speed of 500 megabytes per second.

Professor Daniel Mittleman of Brown University, USA, said: “We found that it is possible to transmit separate data streams using terahertz waves at very high speeds and with very low error rates. In the future, we may have wireless terahertz networks.”

Current audio and data networks use microwaves to transmit signals wirelessly. However, the rapidly increasing demand for data is exceeding the needs of microwave networks.

Terahertz waves have a higher frequency than microwaves and therefore have the potential to carry larger amounts of data. However, scientists are only just beginning to experiment with terahertz frequencies, and many of the fundamental components necessary for terahertz communication do not yet exist.

This was the first time terahertz waves were used to send multiple signals through a single channel. It's called "multiplexing," and it's similar to the technology that allows a single cable to transmit multiple television channels or hundreds of users to access a wireless Wi-Fi network.

However, the authors argue that terahertz technology still needs more time, until regulators begin allocating bandwidth for its use.
