  1. American Radio Relay League The National Association for Amateur Radio When All Else Fails . . . Amateur Radio

  2. Broadband Over Power Line (BPL) and Radio Services Ed Bruette, N7NVPARRL Section Manager - Western WAWA State RACES Officer P.O. Box 73Silverdale, WA 98383-0073n7nvp@arrl.org360-698-0917 Ed Bruette, N7NVP WWA Section Manager, ARRL

  3. BPL Ed Bruette, N7NVP WWA Section Manager, ARRL

  4. PLC? Ed Bruette, N7NVP WWA Section Manager, ARRL

  5. FCC Notice of Inquiry • On April 28, 2003, the FCC released an NOI requesting comments and reply comments on primarily technical issues regarding BPL. The FCC sought information and data on the relevant technology. • In addition, the FCC sought comment on whether it should change the part 15 rules, 47 CFR § 15, to allow for the legal and feasible deployment of BPL. Ed Bruette, N7NVP WWA Section Manager, ARRL

  6. American Public Power Assoc. • 'Given the tremendous potential of BPL to provide an advanced technology that utilizes additional facilities based mechanisms for providing services the burden should be imposed on challengers to BPL to demonstrate interference in a fact based, empirical proof. Ed Bruette, N7NVP WWA Section Manager, ARRL

  7. APPA (cont.) • Further, to the extent that interference is demonstrated, there should be an attempt to accommodate BPL, even if it means that existing communications providers may have to share or transfer bandwidth.' Ed Bruette, N7NVP WWA Section Manager, ARRL

  8. BPL Is Regulated by FCC Part 15 • Carrier-current must meet limits for intentional emitters • Non-interference stipulated in part 15 • Manufacturer responsible for FCC authorization and maximum limits • Operator responsible for harmful interference • Both are important to mitigate possible harmful interference Ed Bruette, N7NVP WWA Section Manager, ARRL

  9. Harmful Interference • Defined as the repeated disruption of radio communications or any disruption of certain emergency communications services • From broadband device (BPL) will interfere with entire band(s)! • Will occur for entire length of line in areas where access BPL is deployed! Ed Bruette, N7NVP WWA Section Manager, ARRL

  10. Potential Spectrum Loss Ed Bruette, N7NVP WWA Section Manager, ARRL

  12. Emergency management National Guard US Coast Guard U.S. Military Fire Departments Law Enforcement CAP FAA FEMA NASA Voice of America TV stations Low Power FM Broadcast Stations BPL Could Interfere With: Ed Bruette, N7NVP WWA Section Manager, ARRL

  13. BPL Could Also Interfere With: • Radio astronomy • Amateur Radio services • Disaster communication networks • Land, fixed, mobile services • Military Affiliate Radio Systems (Army, Navy, Marine Corps, Air Force) • Citizens band Ed Bruette, N7NVP WWA Section Manager, ARRL

  14. Worldwide Problem • BPL was extensively studied in Japan and rejected • Trials continue in Europe • Multiple interference complaints have been documented Ed Bruette, N7NVP WWA Section Manager, ARRL

  15. Organizations Voicing Concern About BPL Interference • FEMA • NTIA • National short-wave listener associations • Short-wave broadcasters • Electronic-equipment manufacturers • GE Medical • Aeronautical Ed Bruette, N7NVP WWA Section Manager, ARRL

  16. The Consumer • Consumers probably will not be aware of the documented interference potential • Early subscribers may be subjected to needless system problems due to the deployment of technology that has yet to be properly tested • Hams at risk Ed Bruette, N7NVP WWA Section Manager, ARRL

  17. NTIA Comment “Notwithstanding BPL’S Potential Benefits, The Commission Must Ensure That Other Communications Services, Especially Federal Government Operations, Are Adequately Protected From Unacceptable Interference.”

  18. NTIA’s Latest Filings • Rejects the idea of BPL ID • Excludes some freqs for aeronautics • Coastal station exclusion zones • Coordination areas around National Radio Quiet Zones • No other protections are mentioned! Ed Bruette, N7NVP WWA Section Manager, ARRL

  19. What’s Happening in WA • Olympia • Chelan/Douglas • Spokane • Walla Walla – Columbia Energy • New Satty – 32 spot beams Ed Bruette, N7NVP WWA Section Manager, ARRL

  22. FCC Action • 6100+ Comments • 14 Oct. – Report and Order from OET • About 2 weeks later the R&O is expected on the street Ed Bruette, N7NVP WWA Section Manager, ARRL
