"I do not think that the wireless waves I have discovered will have any practical application." —German physicist Heinrich Rudolf Hertz, the first person to broadcast and receive radio waves.
It’s fair to say that Heinrich Rudolf Hertz didn’t quite know what he had on his hands when he discovered the radio wave in 1886, but in his defense, the rest of the world didn’t either. While Hertz’s experiments paved the way for technology including the radio, television and mobile phones, it would be years before scientists fully understood the implications of what he’d uncovered.Let’s take a quick look at how wireless communications have evolved from Hertz’s “impractical” radio waves to some of the indispensable technology we use today.
