IN DEVELOPMENT

Ad Hoc networking
	A term refering to peer-to-peer networks in which there is no client/server distinction, but instead where all networked devices are nodes. Currently used to describe non-infrastructure 802.11 networks which allow for multi-hop connections to a fixed internet connection, spontaneous networking between nodes and dynamic network topology (i.e. the area covered changes with the position of the nodes in the network).
Bluetooth
	A short range (10 metres) radio networking technology operating in the 2.4Ghz band, mainly used for personal area networking (communication between different devices such as PDA and moile phone)
Cell Triangulation
	A method of locating a mobile device by triangulating its position from the three nearest base stations. The strongest signal will indicate which mobile phone cell the device is located within.
802.11 (WiFi)
	The name of the IEEE standard for wireless networking in the 2.4 and 5.4Ghz bands of the radio spectrum covering up to 250 feet (100 metres). Also known as Wireless Local Area Network (WLAN). Different specifications include 802.11a, b, g and h.
GPRS
	General Packet Radio Service: a radio technology for mobile phones which breaks information into small 'packets' which can be transmitted individually rather than as a continuous stream as in traditional circuit-switched networks.
GPS
	Global Positioning System: the USA's military satellite system for determining location, also available to civilians (limited to a maximum accuracy of about 15 meters). Qualcomm's Assisted GPS combined signals from b oth satellite and wireless/mobile networks to increase the accuracy of position location.
Mesh Networking
	Alternate description for Ad Hoc Networking.
MobileFi (802.20)
	A new IEEE wireless networking standard providing speeds from 1Mbps to 4Mbps in licensed spectrum below 3.5GHz over distances of about 15km.
PalmOS
	The Palm Operating System for PDAs.
PDA
	Personal Digital Assistant: a handheld computer.
Pocket PC
	Microsoft operating system for PDAs based on Windows CE. A version for mobile phones also exists called Smartphone 2002.
Symbian
	An operating system based on PSION's EPOC, now adopted by many mobile phone manufacturers as the leading operating system for 'smart' mobile phones (e.g. Nokia's Series 60 & Ericsson's UIQ).
3G
	Popular acronym for Third Generation mobile phone systems (see also UMTS).
UMTS
	Universal Mobile Telecommunications System: the generic name for the W-CDMA implementation of Third Generation mobile phone systems (see also 3G).
Waypoint
	A term indicating a location identified through the GPS system (see above).
WiFi (802.11)
	Wireless Fidelity: a generic name for the various implementations of 802.11 wireless networking standard, as popularised by the WiFi Alliance.
WiMAX (802.16)
	A new metropolitan area wireless networking IEEE standard offering point-to-multipoint broadband wireless access in the 10-66 GHz band.
Windows Mobile
	The new name for Microsoft's Windows CE and PocketPC (see above) Operating systems. Released June 2003.
XMLRPC
	Extensible Markup Language Remote Procedure Call.
