Intel is halting production for 60 GHz 802.11ad WIFI on their laptop and thus other add-in modules. The AD WIFI connection uses the 60hz band, and in a direct line of sight you can reach 7 Gbit/s on short distances through docking two devices.

As it seems, the market has very little interest in the new AD spec, few docking stations have been sold. Only a few 802.11ad docking stations have been released. And it likely all has to do with the adoption rate of Intel's Thunderbolt 3 release with USB Type-C allowing you to dock laptops over a wire (at speeds up to 40 Gbit/s).

Manufacturers can place orders for AD compatible add-in cards up-to September 29th, after which deliveries will take place until the end of the year, but after that, AD WIFI is no longer a thing for Intel laptops. Intel might continue to support the 802.11ad spec for other applications though, like wireless-control of VR headsets.
