Power Line Communication (PLC) is a portfolio which in on the 230-volt power supply network House Data from the Internet can be transmitted. "This sounds initially good, but due to the properties of the optical network can radio services are heavily affected and this is often not mentioned, criticized Ulfried Ueberschar the German Amateur Radio Club and refers to the result of the latest test report on power line network adapter (PLC) in the computer image 8 / 2009.
that harmful interference from power lines when operating a PLC modem particular can affect shortwave reception, Ulfried Ueberschar been known for years. He is a ham and a consultant for Electromagnetic Compatibility in the DARC eV, the largest amateur radio club in Germany.
He repeatedly drew attention to the adverse effects that accompany the operation of these devices. Other radio services, such as the broadcast service can be difficult to be affected. The reception at the source of the most interesting international short wave broadcasting is excluded according to experience, or at least limited only by strong radio stations, when light lines near a household with PLC modem to transmit antennas for electromagnetic interference be .
This also confirms the Computer Bild magazine in its issue 08/2009, where the equipment for compliance with the relevant standard EN were tested 55022nd Not a single unit managed the test! In the worst cases, the limit of the radiated electromagnetic interference even by more than a factor exceeded 30 . In reverse, this indicates that none of the devices would have on the European single market can be marketed.
"It's all very reminiscent of that of Chinese toys while carrying a CE mark, however, often does not meet the safety standards or even secrete harmful substances. Where only remains the regulatory element, which prevents this proliferation? "asks Ulfried Ueberschar and calls on the market surveillance devices that are obviously not in accordance with law relating to electromagnetic compatibility, especially to take a close look.
