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. Slide 11

Maintenance items – editorial corrections to C63.10 (2009) – spectrum analyzer use clarified – detector functions, measurement of pulse emissions, and average measurements clarified – reference level, attenuation and headroom (new) – antenna use clarified (new table added) – clarification of test sites > 1 GHz – site must conform to CISPR (2007) – 1-18 GHz – Clarification of test distance for devices operation GHz – streamlined test channels and test mode procedures for UNII and DTS devices – revised text to reduce redundancy, clarify maximization of emissions, establish new procedures for measurements above 1 GHz and introduced new alternative procedure for measurement of small transmitters operating above 1 GHz Slide 12

Injection into a vehicle’s wiring system via the cigarette lighter adapter (CLA) socket. Capacitive coupling to a vehicle FM whip antenna, roof top antenna, or embedded glass antenna. Direct connection to a vehicle FM radio antenna input – New procedures for testing inductive loop devices operating on frequencies below 100 kHz.
