Dinesh Bharadia, 28, a young Indian-origin researcher at the Massachusetts Institute of Technology (MIT), was recently awarded the prestigious US-Based Marconi Society Young Scholar award because of his phenomenal work in the field of radio waves and technology.
Bharadia has solved a problem of Radio Waves that baffled scientists for almost 150 years. He has shown how to send and receive radio signals on the same channel. Bharadia’s research debunked a longstanding notion that radios cannot send and receive signal at the same time on the same frequency due to the interference which will be caused by the matching signal. This technology has got immense potential.
As per the statement released by the society, "Bharadia has been chosen for the 2016 Paul Baran Young Scholar Award for his contribution to send and receive radio (wireless) signals, including mobile telephony and data on the same channel (wave)".
Bharadia’s research disproved a long-held assumption that it is generally not possible for a radio to receive and transmit on the same frequency band because of the interference that results. “Let’s say you are shouting at someone and they are shouting at you,” Bharadia explains. “Neither of you can hear the other, because you are both shouting in the same frequency. The noise in your ears (interference) from your own shout prevents you from hearing the other person. The self-interference cancellation technology developed by Bharadia has made the development of duplex radio a reality. The new technology developed will allow guidance and control of driverless automobiles even in harsh weathers and will also be beneficial for the visually challenged.
Especially, in India, where the concentration of cellphone users is very high, use of this technology will allow doubling the data service. It will also allow better coverage of radio signal without heavy investment for increasing number of towers.
The society is named after Nobel laureate Guglielmo Marconi, who invented the radio. However, the scientist could not solve the problem of duplexing, till date. For Bharadia, the Marconi Young Scholar award is especially rewarding, “Marconi, invented the radio but couldn’t solve the problem of duplexing,” he says. It is also fitting that this work by Bharadia be recognised by the society which was set up by the Nobel laureate’s daughter.
The Indian American researcher Dinesh Bharadia, is an alumnus of the prestigious IIT-Kanpur and Stanford University, and now works at the MIT. He will receive the award at a ceremony at the Computer History Museum in Mountain View, California, on 2nd November, 2016.
