Wireless Working Group
 Established by C63® in 2006 at the request
of the TCB Council.
C63/SC-1/WWG charged with developing
voluntary compliance standards for testing both
licensed and unlicensed transmitters
The procedures for determining compliance of
both licensed and unlicensed transmitters have
not been well documented, or are scattered
throughout of plethora of documents (rules,
KDB’s, 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.
 Work on C63.26 began about 2 years ago.
