Those days will be soon over when people used to had different cables for electricity and data communications. Instead a single power cable will be used for both power supply and data commmunication. In India, most of the high-speed communication service users are cable based till date. An experimental service has already been started in Kolkata. A Delhi Based Organisation Bharat Connect Limited in association with Bengal Engineering and Science University and Calcutta Electric Supply Corporation has started the new experimental service in two Residential blocks of Kolkata, which is christianed as Broadband Over Power Line (BPL).
The technology to supply data through power lines in not new. Countries like USA, Russia, South Africa are already using the technology successfully. In this technology, the gap between the flow of two electron particles are used to transmit data, which lies idle.
This can be a revelutionary technology in India. Connecting all the villages of the country with data communication cables seperately can be very expensive and time consuming. The power distribution infrastructure is already in a better position than data communication structure. This infrastructure can be used to provide internet service to the villages of the country in a quick and cost-effective way.
