Protocol to Access White-Space (PAWS) Databases:
Use Cases and Requirements
Abstract
Portions of the radio spectrum that are assigned to a particular use
but are unused or unoccupied at specific locations and times are
defined as "white space". The concept of allowing additional
transmissions (which may or may not be licensed) in white space is a
technique to "unlock" existing spectrum for new use. This document
includes the problem statement for the development of a protocol to
access a database of white-space information followed by use cases
and requirements for that protocol. Finally, requirements associated
with the protocol are presented.
