We've had this discussion before, but I might as well re-state it. In the right environment, 900 will still have better penetration than 3.65, no matter what fancy trickery telrad has or has not endowed upon it. The TVWS equipment could be an option, although the regulatory uncertainty with the frequencies involved is a bit troubling.
