Wifi is set to go ultrafast

SUPER-FAST wifi 100 times quicker than today is on the horizon using high-frequency radiation waves.

US researchers have for the first time been able to send video signals using terahertz rather than traditional microwaves.

Terahertz waves, which are high-frequency radiation, allow data to travel at 50 gigabits a second. That offers streaming speeds about 100 times faster than those possible today, in which wireless networks reach a top speed of 500 megabytes.

Professor Daniel Mittleman, from Brown University in the US, said: ‘We showed that we can transmit separate data streams on terahertz waves at very high speeds and with very low error rates.’

Tests on terahertz frequencies are, however, at an early stage.
