Potential Interference From Broadband Over Power Line (BPL] Systems To Federal Government Radiocommunication Systems at 1.7 - 80 MHz Phase 2 Study

On October 14, 2004, the Federal Communications Commission (Commission or FCC) adopted a Report and Order that defined new Part 15 rules for Access Broadband over Power Line (BPL) systems. The National Telecommunications and Information Administration (NTIA) contributed to the Commission’s work by providing analysis to support recommendations for refinements in the rules and measurement guidelines in comments and staff correspondence filed in response to the Commission’s earlier BPL Notice of Proposed Rulemaking (NPRM). The NTIA Phase 2 study of Access BPL systems expands on its earlier Phase 1 study by providing additional modeling results and analyses to evaluate the effectiveness of the FCC’s rules and measurement guidelines in minimizing the potential for harmful interference to federal radiocommunication systems under worst-case conditions.
