  TCB Council.
• C63/SC-1/WWG charged with developing voluntary
  compliance standards for testing both licensed
  and unlicensed transmitters

  licensed and unlicensed transmitters have not
  been well documented, or are scattered throughout
  of plethora of documents (rules, KDBs,
  interpretation letters, etc.)
• As a result of WWG work, C63.10 (2013) was
  published and is expected to be used by the FCC
  for testing unlicensed transmitters.
