What are the differences between a typical organisation network and wireless network?

A Wireless Local Area Network (WLAN) is a type of local area network that uses high frequency radio waves rather than wires for communication between devices. A WLAN is a flexible data communication system used as an alternative to, or an extension of a wired LAN. Wireless information communication has enabled people to interact more easily and freely. With the advent of technology, wireless accessibility is becoming increasingly deployed in the office and public places. WLAN is based on the IEEE 802.11 standard. Different standards such as 802.11a, 802.11b and 802.11g have since then evolved supporting different frequency spectrums and bandwidths. There are two related IEEE standards - 802.1X and 802.11i. The 802.1X, a port-level access control protocol, provides a security framework for IEEE networks, including Ethernet and wireless networks. The 802.11i standard was created for wireless-specific security functions that operate with IEEE 802.1X. A WLAN should be implemented with ...  more
