An affordable broadband connectivity can help solve various problems facing the rural areas of India. Acknowledging this need, IIT Mandi is working on a cognitive radio system that will enable free communication between mobile devices.

Professor Rahul Shrestha and his research scholar Rohit Chaurasiya, at IIT Mandi, along with Mahesh Murty from International Institute of Information Technology (IIIT) Hyderabad, have developed methods to improve hardware efficiency of Cognitive Radio (CR) devices.

Improving the hardware efficiency of CR devices will enable people, especially those living in remote areas, to communicate through mobile devices at zero cost.

Their work was recently published in the journal IEEE Transactions of Circuits and Systems.

Cognitive Radio to help alleviate spectral paucity issue

Cognitive Radio is an emerging intelligent technology used to transfer information through space to long distance. It is a very helpful medium for interruption-free and affordable wireless communication.

This technology is increasingly being used to expand the use of the radio frequency waves (RF) and alleviate the problem of spectral paucity.

A cognitive radio system could lead to affordable broadband connectivity in India especially to rural areas and large-scale Wi-Fi’s in public locations.

Professor Shrestha said that cognitive radio can essentially solve the problems of common people in the rural or untouched areas, by enabling them to communicate without paying anything (except for the device).

The system can also help in cost-effective communication among the common people in urban cities.
