Local Area Wireless Networks (LAWNs), commonly known as Wireless LANs (WLANs), typically use Orthogonal Frequency-Division Multiplexing (OFDM) as the modulation technique. OFDM is a method of encoding digital data on multiple carrier frequencies. It is known for its efficiency in carrying high data rates over radio waves and its robustness against narrowband interference and frequency-selective fading due to multipath. This makes OFDM a suitable choice for LAWN environments where such conditions are prevalent.
