Orthogonal Division Frequency Multiplexing (OFDM) may not be at the center of your radar screen, but if you build wireless systems or applications, you should be learning about OFDM and what it does for wireless communications. A technology foundation of WiMAX [1], OFDM will be a key ingredient in allowing mobile WiMAX to have an impact on the work life of mobile professionals. OFDM makes it possible to squeeze more channels and more effective bandwidth into a given slice of radio spectrum--that's a win for WiMAX [2], the service providers, and the users.
