            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.
