Wireless LAN:

Wireless LANs are often used for connecting to local resources and to the Internet

• A wireless local area network (WLAN) links two or more devices over a short distance using a wireless distribution method, usually providing a connection through an access point for internet access.

•  The use of spread-spectrum or OFDM technologies may allow users to move around within a local coverage area, and still remain connected to the network.

• Products using the IEEE 802.11 WLAN standards are marketed under the Wi-Fi brand name.

•  Fixed wireless technology implements point-to-point links between computers or networks at two distant locations, often using dedicated microwave or modulated laser light beams over line of sight paths.

•  It is often used in cities to connect networks in two or more buildings without installing a wired link.
