Wireless Working GroupWireless 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.
