Attenuation and noise level : potential problems with communication via the power grid

• This paper will give examples of the potential problems associated with remote-meter reading via the power grid and describe some of the technologies available. Examples will be given of practical cases in which the communication channel does not function in the intended way. Three potential problems with communication via the power grid are identified in the paper:The noise level is too high for the information to reach the receiverThe attenuation at the frequencies used for communication is too high. Several cases have been identified where this made communication impossible. Certain types of end-user equipment cause a large attenuation of the communication signal, so that a too small amount of the signal reaches the receiverInterference with other equipment. A flicker problem was found due to a modulated 100-Hz signal used for communication
