What is 802.11ax Wi-Fi, and what will it mean for 802.11ac

Each new Wi-Fi standard has brought significant improvements in performance, with the most recent, 802.11ac, offering an impressive theoretical maximum rate of 1.3Gbps.  Unfortunately, these gains have not been enough to keep pace with demand, leading to that exasperated cry heard across airports, malls, hotels, stadiums, homes and offices: “Why is the wireless so slow?”

The IEEE is taking another crack at boosting Wi-Fi performance with a new standard called 802.11ax or High-Efficiency Wireless, which promises a fourfold increase in average throughput per user.

802.11ax is designed specifically for high-density public environments, like trains, stadiums and airports. But it also will be beneficial in Internet of Things (IoT) deployments, in heavy-usage homes, in apartment buildings and in offices that use bandwidth-hogging applications like videoconferencing.
