In the era of technology, 5G is just around the corner. Despite its more recent applications in the industry, the technology itself has a long history which is rooted in India.

The Indian behind 5G internet
Thanks
to Sir Jagadish Chandra Bose contributions, the world will reap the benefits of
5G Internet very soon!
Milimetre
Wavelengths
Born
on 30 November, 1858, at Mymensingh, now in modern day Bangladesh -- Sir
Jagadish Chandra Bose attended Cambridge after studying physics at Calcutta
University.
He was the first to demonstrate radio communication with millimetre wavelengths, which fall in the 30GHz to 300GHz spectrum.
Short
Wave Communication
The
Institute of Electrical and 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 nearly 120 years later.
Bose generated 5mm electromagnetic waves, 60GHz, before
instruments even evolved to measure frequencies that low. The millimetre wave
that J C Bose worked on is the backbone of developing 5G.
Understanding
the Phenomena
While
Italian inventor Guglielmo Marconi is credited with first inventing the
telegraph in 1895, Bose was working to understand the nature of the phenomenon
Modern Day Usage
Bose's
millimetre waves have found applications in a variety of fields since their
discovery over a century ago — they're used in everything from radio telescopes
to radar and, more recently, for collision-warning systems and cruise control
in modern day cars.
From
wave guides to Microwaves
Bose
invented the crystal radio detector, waveguide, horn antenna, and other
apparatus used with microwave frequencies.
