Mesh topology network based on Wi-Fi standards but typically linked together by proprietary extensions. The Wi-Fi Alliance Task Group 802.11s is developing an IEEE standard for Wi-Fi mesh. See also mesh network.

UMTS standard for 3G digital mobile networks, using CDMA technology. It is the evolution path for GSM and EDGE to UMTS and offers increased voice capacity and theoretical peak data speeds of up to 2 Mbps. The 3GPP task group continues to work on the evolution of WCDMA toward 4G and has defined a series of evolutionary steps:
R.99 (Release 99) — Specifications (completed in 1999) for the original version of WCDMA, a 3GPP standards project to define the requirements and basic framework for UMTS 3G mobile networks. R.99 defined the UTRA and the basic features of this early 3G development.
R.4 (Release 4) — Specifications (released in 2004) for the next evolution beyond R99. R4 was the first step toward an all-IP core network, adding separation of the control channel from the connection in the circuit-switched core network, and basic VoIP routing.
R.5 (Release 5) — Specifications (released in 2005) for the next evolution beyond R4. R.5 extends WCDMA to include HSDPA and HSUPA for high-speed packet data services and IMS for multimedia and converged IP network support. It added IP transport in the UTRAN.
R.6 (Release 6) — Specifications (completed in 2006) for the next evolution beyond R5. R.6 extends WCDMA to include MBMS for mobile TV services, PoC and EUDCH for enhanced uplink speeds and system capacity. R.6 adds IMS Phase 2 and UMTS/WLAN interworking.
R.7 (Release 7) — Also known as LTE, the specifications (frozen at the end of 2007) for the next evolution beyond R.6. It will add radio enhancements, MIMO, end-to-end IP telephony and evolved EDGE. See also LTE.
R.8 (Release 8) — Further extension of LTE and SAE capabilities prior to the advent of 4G. R.8 is likely to add OFDMA for the downlink and SC-FDMA for the uplink in the UTRAN. R8 specifications were frozen in December 2008. See also LTE and SAE.

WAN optimization controllers (WOCs) in the enterprise WAN enable application centralization by mitigating latency effects and reducing bandwidth costs through the use of bandwidth reduction algorithms, network-level optimization, and other application layer protocol spoofing and optimization techniques that may compensate for lossy links. SoftWOCs provide these benefits to individual devices. WOCs are used for data-center-to-data-center WAN links for data replication to support business continuity/disaster recovery (BC/DR) requirements.
Industry:Technology
A communications network that connects computing devices over geographically dispersed locations. While a local-area network (LAN) typically services a single building or location, a WAN covers a much larger area such as a city, state or country. WANs can use either phone lines or dedicated communication lines.
Industry:Technology
An entity that owns/operates a telecom network and sells network capacity to other telecom service providers.

Website experience analytics is a subset of advanced web analytic techniques for analyzing how effectively a website provides a net positive user experience that could drive website purchase or consumer engagement.
Industry:Technology
A website is a collection of files accessed through a web address, covering a particular theme or subject, and managed by a particular person or organization. Its opening page is called a home page. A website resides on servers connected to the web network and is able to format and send information requested by worldwide users 24 hours a day, seven days a week. Websites typically use HTML to format and present information and to provide navigational facilities that make it easy for the user to move within the site and around the web.

Web-oriented architecture (WOA) is a substyle of service-oriented architecture (SOA) that leverages Web architecture. It emphasizes the generality of interfaces (user interfaces and APIs) via five fundamental generic interface constraints: resource identification (e.g., uniform resource identifier (URI)), manipulation of resources through representations (e.g., HTTP), self-descriptive messages (e.g., Multipurpose Internet Messaging Extensions (MIME) types), hypermedia as the engine of application state (e.g., links) and application neutrality.
