Members of Regulatory Affairs group of the Dynamic Spectrum Alliance (DSA) have been putting their heads together to review regulatory practice across the world, on access to the TV white spaces and have assembled a Model set of rules. Most of the development work on regulations has been undertaken by the FCC and Ofcom (UK), working with industry.
The intention is to help administrations which have not yet investigated introduction of TV white spaces technology to get up the learning curve faster. The documents provided on the DSA website include:
- The Model Rules backgrounder introduces the significance of access to the TV white spaces and the key components of the sharing mechanism designed to protect existing users of the band, namely terrestrial TV viewers and wireless microphone users
The model rules are based around the use of geolocation databases, with white space devices reporting their positioning in order to determine what spectrum is available to use. They include the concept of master and client devices, where the master device acts an intermediary between client devices and databases. Clients need only consult their local master device in order to determine which channels are safe to use.
