Remote monitoring of power frequency electrical signals employing GSM network

Mobile phones are the backbone of modern day communication system and have undergone an immense growth in recent years. The use of mobile phones is no longer limited only to the traditional applications of call and messaging. Current research trends indicate that mobile phones are being used for a variety of innovative applications such as mobile-based sensing and data communication. With this in mind, and with such widespread availability of mobile towers and ready infrastructure, a unique application of the mobile network can be to communicate technical information regarding the condition of an electrical system. Thus, this paper proposes a method, whereby it is possible to transmit power frequency electrical signals over the GSM voice channel. as a means for low cost, yet state of the art, remote condition monitoring system.
