This technologically very cool but those frequencies are too easily blocked to be useful without other changes. We'd be reaching for the sky to get our phone's data working. A combination of 100Gbps wireless and fiber in a small chipset could be a winner. This would enable dense arrays of short-range transceivers to be mounted on existing infrastructure. It would have to be very small, like 4cm cubed, and use daisy chain cabling thinner than a few mm. Anyone who's seen a large grid of 5GHz WiFi transceivers on Cat 6 knows that high performance wireless tech needs to get a LOT smaller to be practical.
