First Millimeter-wave Communication Experiments by J.C. Bose, 1894-96
Sir Jagadish Chandra Bose, in 1895, first demonstrated at Presidency College, Calcutta, India, transmission and reception of electromagnetic waves at 60 GHz, over a distance of 23 meters, through two intervening walls by remotely ringing a bell and detonating gunpowder. For his communication system, Bose developed entire millimeter-wave components such as: a spark transmitter, coherer, dielectric lens, polarizer, horn antenna and cylindrical diffraction grating.

In the space below the line, please describe the historic significance of this work: its importance to the evolution of electrical and computer engineering and science and its importance to regional/national/international development.
In 1895, Jagadish Chandra Bose first demonstrated in Presidency College, Calcutta, India, transmission and reception of electromagnetic waves at 60 GHz, over 23 meters distance, through two intervening walls by remotely ringing a bell and detonating some gunpowder. For his communication system, Bose pioneered in development of entire millimeter-wave components like: spark transmitter, coherer, dielectric lens, polarizer, horn antenna and cylindrical diffraction grating.
This is the first Millimeter wave communication system in the world, developed more than 100 years ago. This is the oldest Milestone achievement from Asian continent.
What features or characteristics set this work apart from similar achievements?
For his communication system, Bose pioneered development of a host of millimeter-wave components that included: spark transmitter, coherer, dielectric lens, polarizer, horn antenna and cylindrical diffraction grating. Bose chose quasi optical Millimeter wave frequency range.The wavelengths he used ranged from 2.5 cm to 5 mm. The reason for the choice of millimeter wave by Sir J.C. Bose was primarily due to the advantage of studies of quasioptical properties of the radio waves within his laboratory of limited size, that was available to him at the Presidency College. However, the components and systems developed by Sir J.C. Bose, initially at millimeter wave and subsequently at microwave, were outstanding discoveries made more than 100 years ago, in Calcutta, India, most of which are now being utilized, in a modernized form for Earth/space links and remote sensing.
