Qualcomm's latest 60GHz chips aren't the first to hit the market. There have been routers in the past that used the 802.11ad standard at 60GHz. The problem with 802.11ad at 60GHz was its limited range, meaning users had to essentially be sitting right next to their router with no physical interferences. 802.11ay solves the distance issues (some tests have shown transmission ranges of over 300 meters), but it still has problems penetrating walls. There's also the 802.11ax standard that's still in development which won't travel as far, but it will have better penetration.
There are certain use cases where 802.11ay makes a lot of sense, one being VR. At the moment, a high end headset like the Oculus or Vive, requires a wire to be tethered to the computer. But with these chips, as long as the user is close to their computer, there will be no need for wires.
Qualcomm also claims that this new 60GHz standard can support new WiFi Sensing applications, like presence detecting, gesture recognition, room mapping, precise location, and improved facial feature detection. Now that Qualcomm's new 802.11ay chips are available, truly immersive and wireless VR might finally be attainable.
Correction, 10/18/18, 1PM ET: This post originally referenced NVMe SSD speeds as a comparison for 802.11ay speeds, but it equated speeds measured in GB/s with speeds measured in Gbps. We've removed the incorrect comparison and apologize for the error.
