The latest update to the Wi-Fi protocol standard, 802.11ax, has been designed to transmit data even faster, to better negotiate bandwidth among several computers and other devices connected to a network, and to more reliably deliver high-bandwidth applications to them, such as streaming video, than the protocol standard it succeeds, 802.11ac.
To take advantage of these gains, client and networking devices need to have hardware that supports the new protocol, of course. Many network device makers have announced 802.11ax products to come. They’ve also filed 802.11ax devices with the FCC for licensing, which reveal more technical information about them.
