SK Telecom and Quantenna push the boundaries for 802.11ax

Pre-standard chips for the emerging 802.11ax standard are starting to appear and now SK Telecom has shown off its own implementation of 11ax, with ‘5G’ speed levels of up to 4.8Gbps. Although the Korean operator has apparently done considerable inhouse work to boost the WiFi speed to this level, the demo does highlight how WiFi standards are evolving capabilities, from higher data speeds to lower power, which are generally associated with cellular 5G. SKT’s implementation of 11ax, which will be ratified next year and which is particularly suited to high density environments, uses 4×4 MIMO and 160 MHz of bandwidth. It supports OFDM-A, multiuser MIMO and dynamic sensitivity control (DSC) technology to improve network efficiency. The operator plans to start…
