Abstract
There are provided systems, devices and methods for detection and/or prevention of power line communications. In particular, there are provided systems, devices, and methods for preventing and/or detecting the possibility to communicate with an end unit via power line communication.
Claims20
A device for prevention of power line communication (PLC), between an unprotected side and a protected side, the device comprising:
- a PLC detector configured to identify the presence of any type of PLC transmission, at the protected side and/or the unprotected side;
- a power supply;
- at least one PLC filter, configured to attenuate any type of PLC signal from the unprotected side to the protected side and vice versa;
- and
- a dedicated PLC noise generator, configured to generate noise at a frequency range of about 3 KHz-100 MHz, and to add the generated noise to the powerline, after the PLC signal has been attenuated by the PLC filter;
- wherein the device is configured to specifically prevent communication over power line, between the unprotected side and the protected side.
A method for prevention of power line communication (PLC), between an unprotected side and a protected side, the method comprising:
- detecting PLC, using a PLC detector, at the protected side and/or the unprotected side;
- filtering PLC, using one or more PLC filters, configured to attenuate any type of PLC signal, wherein the filtering is performed from the unprotected side to the protected side and vice versa;
- and
- generating, using a PLC noise generator, PLC noise at a frequency range of about 3 KHz- 100 MHz, and adding the generated noise to the powerline, after the PLC signal has been attenuated by the PLC filter.
A system for prevention of power line communication (PLC), between an unprotected side and a protected side, the system comprising:
- an end unit;
- and
- a device for prevention of power line communication (PLC), between an unprotected side and a protected side, said device comprises:
- a PLC detector configured to identify the presence of any type of PLC transmission, at the protected side and/or the unprotected side;
- at least one PLC filter configured to attenuate any type of PLC signal from the unprotected side to the protected side and vice versa;
- and
- a dedicated PLC noise generator configured to generate noise at a frequency range of about 3 KHz-100 MHz, and to add the generated noise to the powerline, after the PLC signal has been attenuated by the PLC filter.
