FCC Part 15 has been amended with new rules covering BPL systems. In July of 2009, a request for further comment was issued (See previous post), this is the conclusion of the commission’s response to the directives of the DC Circuit Court of Appeals remand, after a challenge by the National Association for Amateur Radio, AKA American Radio Relay League (ARRL).
In this rule change, the commission finds that the information submitted in response to the RFC/FNPRM does not warrant any changes to the emissions standards or the extrapolation factor. The rules do include some notable changes, among them, modification of the rules to increase the required notch filtering capability for systems operating below 30 MHz from 20 dB to 25 dB, and, establishing a new alternative procedure for determining site-specific extrapolation factors generally as described in the RFC/FNPRM, furthermore, adopting a definition for the “slant-range distance” used in the BPL measurement guidelines to further clarify its application.
