English Glossary 802.11g and b: 802.11g and 802.11b are wireless standards that communicate in the 2.4 GHz band. 802.11g provides speeds up to 54 Mbps. 802.11b provides speeds up to 11 Mbps. Ad hoc network: A type of wireless network in which devices directly communicate with each other rather than through a Wireless Access Point (WAP). Ad hoc networks are typically small and simple (for example, two wireless PCs or a wireless PC and a wireless printer). Performance on these types of networks can degrade if more than six devices are on the network. Ad hoc networks are also known as "computer-tocomputer networks," "peer-to-peer networks," "independent basic service stations (IBSS)," or "direct-connect wireless networks." Authentication: Authentication is a wireless network security strategy. On a network with authentication, devices use a shared key as a password and communicate only with devices that know the key. Unlike WEP, authentication does not encrypt the data sent between wireless devices. However, authentication can be used in conjunction with WEP. Authentication keys and WEP keys can be identical. Channel: One of several pre-set frequencies at which 802.11-enabled devices communicate in order to reduce interference. The number of channels available varies by country/region. Embedded Web server (EWS): The printer embedded Web server is a networking configuration utility that is accessed through an Internet browser. For more information, see "Embedded Web server (EWS)" on page 50. Encryption: A network security strategy that encodes the data sent across a wireless network making the data unintelligible to eavesdroppers. The printer supports WEP and WPA. Encryption keys: A sequence of characters or digits that a wireless device uses to encode data. Encryption keys can be static (as they are in WEP) or dynamic (as they are in WPA). 58
