What is C2PC?

C2PC stands for Class 2 Permissive Change. In the context of wireless devices and regulatory compliance (particularly with the FCC in the United States), a C2PC is a type of modification to a certified device that requires a new grant of equipment authorization. This type of change is permissive, meaning it's allowed under existing regulations, but it's significant enough that the FCC needs to review it to ensure compliance is maintained. Examples of changes requiring a C2PC can include adding new features, modifying the transmitter's parameters, or changing the antenna. Essentially, a C2PC ensures that modifications to a certified wireless device don't violate FCC rules or negatively impact its performance and safety.
