How did Jagadish Chandra Bose’s mercury coherer contribute to wireless communication?

Jagadish Chandra Bose’s mercury coherer was a pivotal advancement in the development of wireless communication. As an early form of radio detector, the device improved the ability to receive electromagnetic waves.12

Its significance was cemented in 1901, when the Italian physicist and inventor Guglielmo Marconi utilized Bose’s mercury coherer to successfully receive the first transatlantic radio signal. By demonstrating the practical application of his research on radio waves, Bose’s work—which also included the development of early semiconductor detectors—laid essential foundations for both wireless technology and the field of solid-state physics.12
