DTU Research - 200MBPS Broadband over power lines on the cards

Delhi Technological University (DTU), formerly known as Delhi College of EngineeringA near-complete research on Broadband over Power Lines (BPL) at Delhi Technological University (DTU), formerly known as Delhi College of Engineering, promises to revolutionalise information technology at a fraction of a cost. If all goes well your power lines will allow access to high-speed internet connection, video surveillance, e-governance, distance education, real-time TV streaming and much more. Monitoring and controlling electronics gadgets at home from office will also become a reality.

The BPL research was initiated in July 2007 and the final report will soon be submitted to the ministry of communication and information technology on March 31, 2010, by the university. The ministry is funding 70% of the project and New Delhi Power Limitsed (NDPL) the remaining 25%.

The pilot has been `tested ok' at Alipur, a village on the GT Karnal road, which "had one of the worst-possible electricity infrastructure'', Vishal Verma, principal investigator from DTU, said.

At present, broadband connection has a speed of 100 MBPS, but BPL promises 200 MBPS and a easy-to-use connection within 30 minutes. "It is fast as the central point is connected to all the nodes which is directly in line with the central server, unlike the conventional practice of branched network or tertiary network. Here, every user is directly connected to the injection point. This doesn't need any additional infrastructure. Just one component at the power line and within 30 minutes the whole building or the neighbourhood can be connected,'' Verma said.

The project has been granted by the ministry as part of its e-governance initiative in rural areas, and thus the pilot run aimed at benefitting the remotest corner of the country.

Broadband connections can be provided using diverse technologies such as fiber optics, satellite, wireless radio (Wi-Max/Wi-Fi), coaxial cable, and telephone twisted pair (DSL), which require extensive investments in order to reach all homes and business establishments.

BPL, on the other hand, allows easy installation with relatively-low entry costs because it requires no wiring changes to enable broadband connection (it can be accessed from any outlet) and makes use of existing power grids without adding a single new cable. Just plug in a device and it is instantly connected to the Internet.

Apart from facilitating implementation of e-governance, there are no limitations to the services that can be provided over power line technology, Verma said. Some of the proven applications where power lines can be used are high-speed internet access, voice over IP (VoIP), video and audio on demand, real time TV streaming, video conferencing, video surveillance systems, telemedicine, traffic and environmental monitoring, e-governance, distance learning, online electrical power metering, load mnanagement, system monitoring and outage reporting. "Interestingly, this system can even be used for surveillance. Cameras can be installed on this electrical network and the data collected can be viewed at the central server,'' Verma said.
