Wireless – Voice and data telecommunications technology that uses the radio-frequency spectrum rather than wires for transmitting and receiving voice, data and video signals. Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path. Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies above the range of human hearing; these are also sometimes classified as wireless.

The first wireless transmitters went on the air in the early 20th century using radiotelegraphy (Morse code). Later, as modulation made it possible to transmit voices and music via wireless, the medium came to be called "radio." With the advent of television, fax, data communication, and the effective use of a larger portion of the spectrum, the term "wireless" has been resurrected.

Descriptive of a network or terminal that uses electromagnetic waves (including rf, infrared, laser, visible light–and acoustic energy) rather than wire conductors for telecommunications.

Word Length - The number of characters or bits in a word.

Each world telephone number consists of a country code followed by the national number. By international agreement, the number of digits in the country code plus national number is limited to a total of 15 digits.

World Time - Time scale, based on the second (SI), as defined and recommended by the CCIR, and maintained by the Bureau International des Poids et Mesures (BIPM). For most practical purposes associated with the Radio Regulations, UTC is equivalent to mean solar time at the prime meridian (0° longitude), formerly expressed in GMT. [NTIA] [RR] Note 1: The maintenance by BIPM includes cooperation among various national laboratories around the world. Note 2: The full definition of UTC is contained in CCIR Recommendation 460-4. (188) Note 3 : The second was formerly defined in terms of astronomical phenomena. When this practice was abandoned in order to take advantage of atomic resonance phenomena ("atomic time") to define the second more precisely, it became necessary to make occasional adjustments in the "atomic" time scale to coordinate it with the workaday mean solar time scale, UT-1, which is based on the somewhat irregular rotation of the Earth. Rotational irregularities usually result in a net decrease in the Earth's average rotational velocity, and ensuing lags of UT-1 with respect to UTC. Note 4: Adjustments to the atomic, i.e., UTC, time scale consist of an occasional addition or deletion of one full second, which is called a leap second. Twice yearly, during the last minute of the day of June 30 and December 31, Universal Time, adjustments may be made to ensure that the accumulated difference between UTC and UT-1 will not exceed 0.9 s before the next scheduled adjustment. Historically, adjustments, when necessary, have usually consisted of adding an extra second to the UTC time scale in order to allow the rotation of the Earth to "catch up." Therefore, the last minute of the UTC time scale, on the day when an adjustment is made, will have 59 or 61 seconds. Synonyms Coordinated Universal Time , Z Time, Zulu Time.

World Wide Web (WWW) - A HyperText system that allows users to navigate, or look through, linked documents and resources. Also Web, WWW, W3. A global, virtual-network based hypertext information system that uses the Internet as its transport mechanism to display computer screens (or Web pages) of graphical, video, textual, and even audio information. Note: In a hypertext system, one navigates by clicking hyperlinks, which display another document which also contains hyperlinks. In Web navigation, the next document seen could be housed on a computer next door or half-way around the world. Created in 1989 at a research institute in Switzerland, the Web relies upon browsers and the hypertext transport protocol (http), an Internet standard that specifies how an application can locate and acquire resources stored on another computer on the Internet. Most Web documents are created using hypertext markup language (html), a coding system for WWW documents. Incorporating hypermedia (graphics, sounds, animations, video), the Web has become a popular medium for publishing information on the Internet. With the development of secured server protocol (https), the Web is now a commercial medium whereby consumers can browse on-line catalogs and purchase merchandise using secure, encrypted credit card information that is protected from interception. Synonym Web.

The World Wide Web is an international, virtual-network-based information service composed of Internet host computers that provide on-line information in a specific hypertext format.

W-Profile Fiber - A single-mode fiber that has two claddings. Note 1: Each cladding has a refractive index that is lower than that of the core. Of the two claddings, inner and outer, the inner cladding has the lower refractive index. Note 2 : A doubly clad fiber has the advantage of very low macrobending losses. It also has two zero-dispersion points, and low dispersion over a much wider wavelength range than a singly clad fiber. (from the fact that a symmetrical plot of its refractive index profile superficially resembles the letter W). Synonyms depressed-cladding fiber, depressed-inner-cladding fiber, doubly clad fiber.

Wrapping - 1. In a network using dual counter-rotating ring architecture, reconfiguration to circumvent a failed link or node. 2. In open systems architecture, the use of a network to connect two other networks, thus providing an increased interaction capability between the two connected networks.
