802.11ac, or Wi-Fi 5 was released in 2014, and at the time, was the newest, fasted, and most reliable version of Wi-Fi. However, 802.11ax, or Wi-Fi 6, is scheduled to be released later this year, and with a number of shiny new features, stands to replace Wi-Fi 5 as the best connectivity option available.
A number of successful commercial and industrial trials of the next generation of Wi-Fi have already been performed by companies like Cisco, Boingo and the Wireless Broadband Alliance.
