Signaling System

Tesla's signaling system, patented in 1900 like U.S. Patent 723,188, enabled secure wireless communication using tuned circuits for selective transmission. Building on his oscillators, it prevented interference via frequency matching, foundational to radio. Demonstrated with his teleautomaton boat, it influenced broadcasting.

Disputes with Marconi overshadowed it, but it advanced telecommunications. Today, it underpins Wi-Fi and cellular networks. Tesla's system revolutionized information exchange, his legacy in connectivity.
