South Korea’s Ministry of Science and ICT said on Thursday that it has approved 1.2GHz of spectrum in the 6GHz band — the 5,925MHz to 7,125MHz range — for unlicensed use.
With the ministry’s approval, South Korea will become the second country to make the 6GHz band available for unlicensed use after the United States gave the go-ahead in April.
The decision will make the whole 6GHz band at under 25mW available for free use at indoor settings across the country.
For device-to-device connections like tethering, spectrum sitting in the 5,925MHz-6,455MHz range will also be available for use everywhere, regardless of whether it is indoors or outdoors. According to the ministry, the decision to allow device-to-device connections in the 6GHz band is a world-first.
It will also provide more channels for Wi-Fi as well as improve data transfer speed levels to that of 5G networks, the ministry said.
In the ministry’s own testing, it demonstrated that 6GHz Wi-Fi could reach speeds of 2.1Gbps, which is five times faster than the currently available Wi-Fi speed of around 400 to 600Mbps.
