SEOUL – WiFi is a popular wireless networking technology that uses radio waves to provide high speed wireless internet and network connections. Wireless routers provide access to the Internet or to private computer networks. Radio waves in the 2.4 gigahertz (GHz) to 5 GHz bands have been widely used around the world.
South Korea has attempted to lead the commercialization of WiFi 6E, the next-generation standard that means WiFi 6 is extended to the 6 GHz band, which brings more bandwidth, faster speeds, and lower latency. , thus opening up resources for future innovations.
At an event organized by the Ministry of Science and ICT on December 3, WiFi 6E was tested in various ways on the southern resort island of Jeju. An 8K VR real-time streaming service was featured in a virtual reality theme park in a Jeju arboretum. Wi-Fi 6E can deliver a more vivid virtual reality experience.
In a high school gymnasium, participants watched a game at the same time on about 100 terminals using a relay camera and a 6E Wi-Fi router. A university cafÃ©-restaurant has set up a remote ordering service. If a QR code attached to each table is photographed, a cell phone displays a menu for orders and payment. A 6E Wi-Fi roaming service has been tested at an airport.
âMany foreign countries provide 6 GHz bands over 6E Wi-Fi as a reference to our policies, and this demonstration seems to be a good example,â said Choi Woo-hyuk, senior ministry of science official responsible for radio policy. , in a press release. “We will continue to actively consider institutional support such as relaxing production standards to revitalize the market.”
South Korea has installed wireless hotspots in public areas to provide citizens with easy access to information and reduce communication costs. Most public access points provide Internet access using 2.4 GHz. In September 2021, mobile carriers introduced a 5G 28 GHz public Wi-Fi service inside Seoul subway trains. The 28 GHz 5G network can deliver data at faster speeds in a smaller area where data traffic is concentrated. .
