But not actually White Space at all. It's fully managed
TV transmitters can't change frequency.
Proposed TV White Space is unmanaged and the idea is the ordinary public buys devices using the TV band. There is no way to Police it, ensure all TV users are OK or detect gadget users adding too big aerials, more power or disabling database.
With so called TV White Space there is no mechanism for TV receivers to report which channel they are really using due to local topology. Which may not be what the official database predicts. Nor can the TV transmitters change.
This Nokia scheme is fully managed sharing and can work. Not really white space at all. TV White Space is a totally evil concept making broadcast users into unprotected secondary users.
