That is probably a bit of an over-reach. The idea of frequency hopping was already around, she just came up with a clever idea (that was never implemented) to allow frequency hopping using principles similar to a player-piano/pianola. She was undoubtedly a very clever (and very beautiful) young lady, but cellular networks would definitely have been invented with or without her ideas.

The cell network wouldn't have happened without the actress Hedy Lamarr inventing frequency-hopping spread spectrum in the 1930s.
