Wideband Integrated Dispatch Enhanced Network (WiDEN) is a software upgrade developed by Motorola for its iDEN-enhanced specialised mobile radio (or ESMR) wireless telephony protocol. WiDEN allows compatible subscriber units to communicate across four 25 kHz channels combined, for up to 100 kbit/s of bandwidth. The protocol is generally considered as a 2.5G wireless cellular technology.

Wi-Fi Alliance is a non-profit international association formed in 1999 to certify interoperability of WLAN products based on the IEEE 802.11 specification. Currently, the Wi-Fi Alliance has over 200 member companies from around the world, and over 1,000 products have received Wi-Fi certification since the certification began in March of 2000. The goal of the Wi-Fi Alliance's members is to enhance the user experience through product interoperability.

Wireless Fidelity (WiFi or Wi-Fi), originally Nick named for 802.11b for wireless LAN with bandwith up to 11 Mbps, now refers to the entire wireless LAN technologies including 802.11a, 802.11b, 802.11g and 802.11n etc. Wi-Fi is actually the industry name for wireless LAN (WLAN) communication technology related to the IEEE 802.11 family of wireless networking standards.

WAP Identity Module (WIM) is the security module implemented in the SIM card for WAP applications. WIM provides security services for WAP applications, and allows you to use digital signature. SIM cards with security module are provided by the SIM card issuer

WiMax, abreviated from Worldwide Interoperability for Microwave Access, is a popular name of the 802.16 wireless metropolitan-area network standard, including both 802.16-2004 for fixed WiMAX and 802.16-2005 for mobile WiMAX. WiMax has a range of up to 31 miles. Data rates for WiMax can reach up to 75 Mbps (Fixed) or 15 Mbps (Mobile). A number of wireless signaling options exist ranging anywhere from the 2 GHz range up to 66 GHz. WiMax is primarily aimed at making broadband network access widely available without the expense of stringing wires (as in cable-access broadband) or the distance limitations of Digital Subscriber Line. WiMax technology can deliver high-speed Internet access to rural areas and other locations. WiMax also offers an alternative to satellite Internet services.

WiMedia Alliance is an industrial association with a focus on UWB (Ultra WideBand) wireless technologies to promote and enable the rapid adoption and standardization of UWB worldwide for high-speed wireless, multimedia-capable personal-area connectivity in the PC, CE and mobile market segments; to provide a neutral and open forum for multiple industry segments to establish requirements, specifications and best practices for usability and interoperability; to promote worldwide UWB spectrum regulations; and to develop, maintain, enhance and reference technical specifications.

Wireless Bridge is a networking bridge used to connect two or more separate networks. A wireless bridge functions in the same way but can be used in situations in which running a wire or cable would be impractical or prohibitively expensive, such as creating a 10-mile point-to-point link.

Wireless FireWire, also known as wireless 1394, is a wireless version of the high speed FireWire communications protocol defined in the IEEE 1394. It allows multiple FireWire devices to communicate wirelessly over IEEE 802.15.3 (UWB) Wireless Personal Area Networks (WPANs). The wireless 1394 specification adapts the IEEE 1394 and P1394.1 bridging standards to the high bandwidth wireless network connectivity enabled by IEEE 802.15.3.

Wireless routers are actually routers with Ethernet plus wireless access points so that they have both wired and/or wireless at the same time. Another combination is to build a DSL or cable modem with the wireless access point, in which the wireless access point is used to communicate with local PCs and other devices and the DSL and cable modem will communicate with the Inernet.

Wireless local-area networks (WLAN or wireless LAN) use radio waves to connect a user device to a LAN, which extends an existing wired local area network. WLAN provides Ethernet connections over the air and operate under the 802.11 family of specifications developed by the IEEE. WLANs are built by attaching a device called the access point (AP) to the edge of the wired network. Clients communicate with the AP using a wireless network adapter similar in function to a traditional Ethernet adapter. The WLAN technology is defined by the IEEE 802.11 family of specifications, namely, 802.11, 802.11a, 802.11b, 802.11g and 802.11n. All use the Ethernet protocol and CSMA/CA (carrier sense multiple access with collision avoidance instead of CSMA/CD) for path sharing.

Explanation : Storing certain input or output on disk for low-speed processing while allowing the computer to continue its normal operations. Spooling is used for printers, plotters, sending email, and other peripheral operations. For example, a file to be printed is sent to the print spooler to wait its turn in the print queue until the printer is ready. Transferring data to the spooler is much faster than printing. While waiting for the file to print, the user can continue to input data, edit files, create new files, etc.
