Rather than transmitting data through a phone line, digital subscriber line or high-speed cable, a wireless Internet network transmits data the same way that radios and c ell phones do: radio waves. These systems all operate on the principle of antenna diversity, which engineers have exploited in long-distance communications systems for decades. Dual Wi-Fi antennas operate on a principle known as antenna diversity, which offers two different reference points for signal reception or transmission (or both) and uses the better one.
