WAN – Wide Area Network
Any Internet or network that covers an area larger than a single building or site.

Web Browser
An application such as Microsoft Internet Explorer that enables you to view web pages on the World Wide Web, on another network or on your computer. A browser also enables you to jump from one web page to another by following links and to download files from the Internet to your computer.

Wireless Local Area Network
The wireless extension to the wired LAN is a growing market. More organisations have people on the road that need touchdown areas in the office. Wireless is the easiest way to facilitate this. There is also the roaming factor where people need to roam within buildings and need access to central systems. The standard on which most WLANs are currently based is 802.11b. It is a revision of 802.11 standard allowing data rates up to 11Mbps in the 2.4Ghz ISM band.

Wireless Standards · 802.11b – The standard on which most WLAN’s are currently based. It is a revision of 802.11 standard allowing data rates up to 11 Mbps in the 2.4Ghz ISM Band. · 802.11a – A revision of 802.11 that operates in the unlicensed 5 GHz band and allows transmission rates of 54 Mbps. 802.11a uses orthogonal frequency multiplexing as opposed to FHSS or DSSS. Higher data rates are available by combining channels. · 802.11g – An extension to 802.11b, 802.11g will broaden 802.11b’s data rates to 54 Mbps within the 2.4 GHz band using OFDM (Orthogonal Frequency Division Multiplexing) technology. An 802.11b radio card will interface directly with an 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. Range at 54 Mbps is less than 802.11b access points operating at 11 Mbps.

Wi-Fi – Wireless Fidelity
Wireless Ethernet Compatibility Alliances (WECA) brand identity for the IEEE 802.11b standard; WECA certification that ensures a product’s compatibility. Wi-Fi5 F – refers to WLAN products based upon the 802.11a specification operating in the 5Ghz radio frequency band. Only products that have passed WECAA interoperability testing are allowed to display the Wi-Fi5 certification logo.

Wireless Wide Area Network
Companies with more than one building on a campus or in close proximity in a city can use Wi-Fi technology – or higher frequency, higher speed radio technologies – to build wireless “bridges” between sites.
