WPA 3 has been announced and it brings some much needed improvements to WPA2. WPA2 has been around for a long time and its time is finally coming to an end thanks to the Wi-Fi Alliance. The primary improvement that should be of note is it will provide individualized data encryption in open networks and prevent others from being able to see what's passing through the network. Other nice improvements are on the way as well and you can see them in the official announcement. Building on the widespread adoption and success of WPA2, Wi-Fi Alliance will also deliver a suite of features to simplify Wi-Fi security configuration for users and service providers, while enhancing Wi-Fi network security protections. Four new capabilities for personal and enterprise Wi-Fi networks will emerge in 2018 as part of Wi-Fi CERTIFIED WPA3™.
