Technology furthers its impact and importance in today’s world. The next big thing coming in the market is 5G. Although it has only recently begun to be applied, the technology itself goes way back into the past, & the credit for it goes to an Indian – Jagadish Chandra Bose.
He was born on 30 November, 1858, at Mymensingh, now in modern day Bangladesh. He attended Cambridge after studying physics at Calcutta University, & was the first to demonstrate radio communication with millimetre wavelengths, which fall in the 30GHz to 300GHz spectrum.
Over a century ago, Jagadish Chandra Bose invented radio communication but Italian inventor Guglielmo Marconi walked away with the credit for the invention. The same millimetre wavelength frequency that Bose had used in his experiment in 1895, is today the foundation of 5G. At last, Bose is getting the credit he deserved.
The Institute of Electrical & Electronics Engineers (IEEE), the largest international body dedicated to advancement of technology, has recognised Bose’s 1895 experiment demonstrating short-wave communication as a milestone achievement. Bose generated 5mm electromagnetic waves, 60GHz, before instruments even evolved to measure frequencies that low. This wavelength is the backbone of the 5G technology.
Not only for 5G, but Bose’s millimetre waves have found application in a variety of fields — they’re used in radio telescopes to radars, & even for collision-warning systems & cruise control!
“In the scientific community, Bose is now gaining recognition as the father of radio science & semiconductors technology. His experiments in early 1890s & early 1900s with mm wave radio frequencies were much ahead of his time – so much so that the time has only come now. While advancement in semiconductor technology led to smartphones, mm wave communication technology may bring about a more wirelessly connected world tomorrow,” said Suvra Sekhar Das, associate professor at the GS Sanyal School of Telecommunication at IIT-Kharagpur.
“Bose was a giant who worked single-handedly at the Presidency College laboratory, overcoming racial discrimination, lack of funding & equipment. Our student resource is still very good. All we need is the right initiative to collaborate with the international scientific community. Bose's experiment was proof of concept. The application happened much later. Now, both of them have to happen simultaneously,” said Debasish Datta, professor of electronics & electrical communication engineering at IIT-Kharagpur.
Legends like Jagadish Chandra Bose make India proud. They stamp their authority in the scientific arena & prove again & again that when it comes to technological discoveries & innovations, India is second to none. ISRO is doing the same these days by rapidly modernising & accumulating achievements that leave the rest of the world in awe.
