  • text of US22. Power Line Carrier Systems We revise the text of US294 and a related reference in Part 90 of the Commission's Rules in order to clearly define the band within which Power Line Carriers (PLCs) must be coordinated in order to protect licensed stations, i.e., the band 9-490 kHz. We note that this action is consistent with Section 15.113(b), which states that: ``The signals from this [PLC] operation shall be contained within the frequency band 9 kHz to 490 kHz.'' We also update a cross reference in Part 15 of the Commission's Rules. Specifically, we revise: 1) US294 by replacing the phrases ``spectrum below 490 kHz'' and ``bands below 490 kHz'' with the phrase ``band 9-490 kHz'' and by

Emissions outside of the 160-190 kHz band must be attenuated by at least 20 dB below the level of the unmodulated carrier. Section 15.113 permits Power Line Carrier (``PLC'') systems on power transmission lines for communications important to the reliability and security of electric service to the public in the 10-1490 kHz band. PLC systems are used to trip protection circuits if a fault, such as a downed power line, is detected in the power grid. In our preparations for the World Administrative Radio

See 47 C.F.R. §§ 15.107(c)(2) and 15.221. This provision does not apply to power line carrier systems, which are subject to 47 C.F.R. § 15.113. See 47 C.F.R. § 15.109(a), (b) and (e).

  • assignments in the Commission's database for this frequency band. In addition, unlicensed devices use the LF spectrum. These systems do not have any allocation status, but are authorized to operate under our Part 15 rules on an unprotected, non-interference basis with respect to all other users. Section 15.209 generally permits unlicensed operation at power limits of 4.9 microvolts/meter. Further, Section 15.113 specifically permits Power Line Carrier (PLC) systems to operate on power transmission lines for communications important to the reliability and security of electric service to the public in the 9-490 kHz band. In this regard, utility companies have generally come to rely on PLC systems to support a variety of monitoring and control functions of the national power grid. For

  • FCC Rcd 21265 (2004). A carrier current system is defined as a system, or part of a system, that transmits radio frequency energy by conduction over an electric power line to a receiver also connected to the same power line. See 47 C.F.R. §§ 15.3(f) and (t), 15.5, 15.31(d), (f), (g) and (h), 15.33(b)(2), 15.107(a)-(c), 15.109(a), (b), (e) and (g), 15.113, 15.201(a), 15.207(c), 15.209(a) and 15.221. Campus radio systems have been operating for over fifty years in the United States at many universities as unlicensed broadcast radio stations in the AM Broadcast band. Initially, the receiver and signal source were attached to the same electric power line. With the advent of the transistor radio, receivers are able to pick up enough
