There are a handful of point-to-point and point-to-multipoint devices that exist that transmit at 5 GHz. How much of that is deployed, I can't say. The FCC's new Spectrum Dashboard is actually a nice tool for looking into who owns licenses in different frequencies and for different services in your area.
