Because the high-frequency carrier signal needs to be injected at the zero-crossing point of the power waveform, the zero-crossing quality will be introduced, which is equivalent to introducing high-frequency harmonics on the power line, which has a great impact on some high-frequency devices on the power line.

Then the wiring must be done in advance, and isn’t it a bit bad to put strong and weak electricity together?

Well, it seems that this is not a new technology, but I just don’t know much about it. . .

Power line carrier has been around for more than 10 years and has been used in the power information collection industry. From the previous narrowband carrier, to the later broadband carrier, to the current HPLC high-speed broadband carrier, and the dual-mode (HPLC+micropower wireless) that is being promoted now, the advantage is that it uses the power line directly, without the need to run a separate

I think LoRa still has limitations, and power line carrier can solve these limitations.

The disadvantages are obvious, which may be the reason why it is not well known by the public. I feel that this is not very practical for daily use at home. There are many problems. The company also bought branded products before, and later bought more expensive ones. When encountering batteries and high-power equipment, no matter how expensive the power cat is, it is useless. Other industry problems

Power line carrier is only used in the substation area, that is, the secondary side of the transformer. When there is frequency fluctuation and other poor power quality, the communication will be disconnected. Power line carrier is used for meter reading at midnight. At that time, the factory information and interference are small.
