WLAN (Wireless LAN)
A Wireless Local Area Network (WLAN) implements a flexible data communication system frequently augmenting rather than replacing a wired LAN within a building or campus. WLANs use radio frequency to transmit and receive data over the air, minimizing the need for wired connections. Enterprises, chain-store operators, banks and the public sector often wish for the efficiency and productivity advantages of Wireless LAN (WLAN) for their branches.
