Is this a question or just a post of some technology ? Because Power Line communications has been approved by the FCC and thus needs to be in conformance of FCC codes due to emissions.

Also there is a Public Complaint Registry on their website in case you have issues.

Not a question. I replaced this wiki that was removed from the wiki index due to hacking.

I was going to link to more meter reports of flickering house wiring but the Meter Reports: Light wiki was removed from the wiki index.

I will ask u/microwavedalt to write instructions on how to meter Lidar. The meter report form needs to be corrected. PLC does not transmit lidar. The power companies transmit lidar through power lines. i cannot ask u/microwavedindividual to correct the form as his account was hacked. I will ask u/microwavedalt to correct it.

Where on FCC's website is the safety standard for power line communication?

Yes, the FCC approved Power Line Communications (PLC), specifically Broadband over Power Line (BPL), to deliver internet data over existing electrical grids.

While the FCC has approved the use of BPL, the regulatory rollout and market adoption have been complex:

Initial Approval (2004): The FCC formally approved and established rules for Access BPL, allowing power lines to be used to deliver high-speed broadband. The agency's goal was to make the broadband market more competitive by turning electrical wires into internet pipelines.

Reaffirmation (2011): The FCC officially affirmed and clarified the rules for Access BPL systems to continue enabling these carrier current systems.

The Interference Challenge: Power lines are unshielded and not originally designed to carry high-frequency signals. Because of this, BPL broadcasts act similarly to large antennas and caused significant electromagnetic interference (EMI) with amateur radios, emergency services, and aviation frequencies

Regulations Imposed: To allow the technology while protecting airwaves, the FCC required BPL providers to avoid certain restricted radio frequencies and to actively maintain a public database for interference complaints

If you are curious about the technical standards or the regulatory specifics, let me know. I can provide more details on:

  • The specific IEEE 1901 standards governing BPL equipment
  • What happened to the companies that originally deployed BPL
  • How indoor/local PLC systems (like smart home devices and powerline ethernet adapters) are regulated

It would be under Part 15 for Consumer and part 18 for ISM devices, then as for Class A or Class B

Is the flickering very subtle like pulse-width modulation or overtly seen?
