How Wireless Networks Work Moving data through a wireless network involves three separate elements: the radio signals, the data format, and the network
OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver
A wireless LAN is a LAN that utilizes radio-frequency communication to permit central or distributed infrastructure devices or computers to operate
