FCC Report and Order(FCC 13-21 and rules modified per Order FCC-14-138)introduced a new regulatory framework for signal boosters，including the introduction of a Network Protection Standard that specifies the technical and operational requirements necessary to minimize the potential for interference from consumer signal boosters to wireless networks.These new requirements are codified in §§ 20.21 and 90.219.

The attachment 935210 D02 Certification Requirements summarizes the certification requirements and associated parameters and definitions for consumer and industrial signal boosters that operate under Parts 20、22、24、27 and 90 of the FCC rules.

The attachment 935210 D03 Signal Booster Measurements provides guidance for demonstrating compliance to the various requirements for Wideband Consumer Signal Boosters as specified in § 20.21(e)，Consumer Signal Booster Network Protection Standard Technical Requirements and Interference Safeguards.

The attachment 935210 D04 Provider-Specific Booster Measurements provides guidance for demonstrating compliance to the various requirements for Provider-Specific Consumer Signal Boosters as specified in § 20.21(e)，Consumer Signal Booster Network Protection Standard Technical Requirements and Interference Safeguards.

The attachment 935210 D05 Indus Booster Basic Meas provides guidance for demonstrating compliance to the various requirements for Industrial Signal Boosters.

Note: The previous attachment 935210 D01 has been expired and the content has been incorporated in 935210 D02.
