SK Telecom employees test the performance of the next-generation Wi-Fi technology “T Wi-Fi AX,” which is four times faster than the original Wi-Fi.

SK Telecom announced that it will commercialize the next-generation Wi-Fi service “T Wi-Fi AX,” which is four times faster than the existing Wi-Fi.

T Wi-Fi AX is a Wi-Fi service based on the 802.11.ax standard, offering the speed up to 4.8 Gbps per access point (AP). This is about four times faster than the Giga Wi-Fi (802.11ac Wave1, 1.3Gbps), which was commercialized in 2013.

However, the smartphones released to date do not have the 802.11.ax chip. As of now, 1 Gbps is the maximum speed. Some flagship smartphones that will be launched next year are expected to run at an increased speed with the maximum data rate of 1.2Gbps due to improved data communication efficiency. With the improved hardware performance of future smart phones, consumers will be able to enjoy the faster Wi-Fi service.

SK Telecom said, "We expect chip and smartphone manufacturers to actively upgrade hardware performance for T Wi-Fi AX." At this point, users are likely to experience an increased speed through T Wi-Fi AX.


T Wi-Fi AX is equipped with a variety of technologies that enable more stable wireless Wi-Fi services even in a traffic-intensive environment. Consumers using the flagship smartphone launched after the Galaxy S8 can use the faster Wi-Fi service without any additional measures.

SK Telecom has built commercial networks centering on core commercial areas such as COEX in Samseong-dong, Seoul, and U-Square in Gwangju, which are dense Wi-Fi usage areas, and it plans to expand the coverage to dense data traffic areas nationwide.
