    Protocol to Access White Space database: PS, use cases and rqmts
             draft-ietf-paws-problem-stmt-usecases-rqmts-02

Abstract

   Portions of the radio spectrum that are allocated to a licensed,
   primary user but are unused or unoccupied at specific locations and
   times are defined as "white space".  The concept of allowing
   secondary transmissions (licensed or unlicensed) in white space is a
   technique to "unlock" existing spectrum for new use.  An obvious
   requirement is that these secondary transmissions do not interfere
   with the primary use of the spectrum.  One approach to using the
   white space spectrum at a given time and location is to verify with a
   database available channels.

   This document describes the concept of TV White Spaces.  It also
   describes the problems that need to be addressed for enabling the use
   of the primary user owned white space spectrum for secondary users,
   without causing interference, by querying a database which knows the
   channel availability at any given location and time.  A number of
   possible use cases of this spectrum and derived requirements are also
   described.
