Advanced Wi-Fi
"We succeeded in developing next-generation technology and an AP for Wi-Fi with a speed of up to 4.8Gbps and successfully demonstrated them in our Bundang building," SK Telecom said on October 23.
This technology is about four times faster than “Giga Wi-Fi (1.3Gbps based on the 802.11ac method)” which is widely used by smartphones.
'Next-generation Wi-Fi' uses four antennas to transmit and receive radio waves and the available frequency bandwidth is 160MHz, twice that of Wi-Fi. The 2.4GHz and 5GHz frequency bands are used.
When next-generation Wi-Fi is commercialized, more stable wireless Wi-Fi service becomes possible even in a heavy traffic environment.
As global manufacturers already released 802.11ax-based chipsets, next-generation Wi-Fi is expected to be commercialized for smartphones as early as next year. Considering the number of antennas (two) and bandwidth (80 MHz), a smartphone with the chipset is expected to achieve up to a speed of 1.2Gbps.
"We plan to build next-generation Wi-Fi APs around heavy traffic areas, "SK Telecom said. Customers will be able to use services with the launch of smartphones loaded with next-generation Wi-Fi-enabled chipsets."
SK Telecom participated in IEEE 802.11ax standard work with Korean small and medium-sized enterprises (SMEs) since 2014 by carrying out national R&D tasks under the management of the Ministry of Science and ICT. Through this, many core technologies were applied to international standards and patents were secured at home and abroad.
