Tesla is most famous for conceiving the rotating magnetic field principle (1882) and then using it to invent the induction motor together with the accompanying alternating current long-distance electrical transmission system (188. His theoretical work and patents still form the basis for modern alternating current electric power systems.

He also developed numerous other electrical and mechanical devices including the fundamental principles and machinery of wireless technology, including the high frequency alternator, the "AND" logic and the Tesla coil, as well as other devices such as the bladeless turbine, the spark plug and numerous other inventions.

I think all this means is that he pretty much invented the radio
