Pseudo-Random Numbers and Wireless Signals?€“ Why Cell Phone Are hard to Tap

Created by Intuitor.com, this page provides an example of pseudo random number generators (PRNG) creating spread spectrum broadcasts and signals for encryption and decryption of wireless transmissions. The page visits the history behind the transmission of wireless signals. It then dives more deeply into how devices today encrypt their signals. Aside from simple description, the site offers an interactive applet which "simulates a spread spectrum broadcast." This is a nice activity which uses mathematics to explain the common technology of wireless communications.
