That's an asset for a lot of indoor applications, as it allows an independent cell in each room, meaning minimal loss of data capacity due to interference between cells in the same band. You need an access point for each room, but that's okay once the hardware is cheap. For new installations, one can wire a building for data, analogous to wiring for lighting, with access points in place of luminaries. Eventually we will see light fittings with inbuilt 60GHz access points? The usage scenario for 60GHz is similar to infrared. The main advantage of 60GHz being that it able to penetrate a wider range of materials, thus offering better coverage.
It will be interesting to see what the patent landscape is for this. I'm hopeful that it will be largely unencumbered, so will become mainstream quickly. The basic system was defined 15-20 years ago, as OFDM based WLAN was always intended to operate in the 60GHz bands [1]. For the last 15-20 years its been a case of waiting for (cheap) radio technology to catch up with, and enable, the original WLAN vision.
