Alcatel-Lucent

Alcatel-Lucent is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Alcatel-Lucent rather than just read about it. In short: Alcatel-Lucent S.A. (French pronunciation: [alkatɛl lysɛnt]) was a multinational telecommunications equipment company, headquartered in Boulogne-Billancourt, Paris, France.

Key takeaways

  • Alcatel-Lucent belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Alcatel-Lucent to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Alcatel-Lucent from memory before moving on to harder problems.

Reference excerpt

Alcatel-Lucent S.A. (French pronunciation: [alkatɛl lysɛnt]) was a multinational telecommunications equipment company, headquartered in Boulogne-Billancourt, Paris, France. The company focused on fixed, mobile and converged networking hardware, IP technologies, software and services, and operated between 2006 and 2016 in more than 130 countries. The American company Lucent Technologies was acquired by the France-based Alcatel in 2006, after which the latter renamed itself to Alcatel-Lucent. Lucent was a successor of AT&T's Western Electric and a holding company of Bell Labs. In 2014, the Alcatel-Lucent group split into two: Alcatel-Lucent Enterprise, providing enterprise communication services, and Alcatel-Lucent, selling to communications operators. The enterprise business was sold to China Huaxin Post and Telecom Technologies in the same year, and in 2016 Nokia acquired the remainder of Alcatel-Lucent. On 3 November 2016, Nokia completed the acquisition, retired the brand name and merged it into their Nokia Networks division. Bell Labs was maintained as an independent subsidiary of Nokia.

History

Predecessor companies

Alcatel-Lucent was formed when Alcatel (originally short for the Société Alsacienne de Constructions Atomiques, de Télécommunications et d'Électronique, a small company in Mulhouse absorbed by CGE in 1966) merged with Lucent Technologies on 1 December 2006. However, the predecessors of the company have been a part of telecommunications industry since the late 19th century. The company has roots in two early telecommunications companies: La Compagnie Générale d'Électricité (CGE) and the Western Electric Manufacturing Company. Western Electric began in 1869 when Elisha Gray and Enos N. Barton started a manufacturing firm based in Cleveland, Ohio, US. By 1880, the company had relocated to Chicago, Illinois, and become the largest electrical manufacturing company in the United States. In 1881, the American Bell Telephone Company, founded by Alexander Graham Bell and forerunner of American Telephone & Telegraph (AT&T), purchased a controlling interest in Western Electric and made it the exclusive developer and manufacturer of equipment for the Bell telephone companies. CGE was formed in 1898 by French engineer Pierre Azaria in the Alsace region of what was then Germany and was a conglomerate involved in industries such as electricity, transportation, electronics and telecommunications. CGE would become a leader in digital communications and would also be known for building the TGV (train à grande vitesse) high-speed trains in France.

Bell Telephone Laboratories was created in 1925 from the consolidation of the R&D organizations of Western Electric and AT&T. Bell Labs would make significant scientific advances including the transistor, the laser, the solar cell, the digital signal processor chip, the Unix operating system and the cellular concept of mobile telephone service. Bell Labs researchers have won 7 Nobel Prizes. Also in 1925, Western Electric sold its International Western Electric Company subsidiary to ITT Corporation. CGE purchased ITT's telecommunications division in the mid-1980s. AT&T re-entered the European telecommunications market in 1984 following the Bell System divestiture. Philips promoted the venture in part because its PRX public switching technology was aging, and it sought a partner to help fund the development costs of digital switching. The joint company used the existing manufacturing and development facilities in The Hague, Hilversum, Brussels and Malmesbury as well as its U.S. resources to adapt the 5ESS system to the European market. The joint venture company AT&T & Philips Telecommunications BV doubled annual turnover between 1984 and 1987, winning major switching and transmission contracts, mainly in the effectively captive Netherlands market. In 1987, AT&T increased its holding to 60% and in 1990 it purchased the remainder of the Philips' holding. In 1998, Alcatel Alsthom shifted its focus to the telecommunications industry, spinning off its Alsthom activities and changing the company's name to Alcatel. AT&T spun off Lucent Technologies in April 1996 with an initial public offering (IPO).

In February 2000, Alcatel acquired Canada's Newbridge Networks. In April 2004, TCL Corporation and Alcatel announced the creation of a mobile phone manufacturing joint venture: Alcatel Mobile Phones. A year later Alcatel sold its share in the joint venture but licensed the Alcatel brand name to TCL, which continues to this day under Nokia. In April 2006, Alcatel announced that it would swap its shares of Alcatel Alenia Space and Telespazio for €673 million and a 12.1% stake in Thales, a key player in the French defence industry. This increased Alcatel's stake in Thales to 20.8%.

Creation of Alcatel-Lucent Facing intense competition in the telecommunications industry, Alcatel and Lucent Technologies merged on 30 November 2006.

Worked examples

Example 1 — a first encounter with Alcatel-Lucent

Start with the simplest possible case. Write down what Alcatel-Lucent claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Alcatel-Lucent before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Alcatel-Lucent ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Alcatel-Lucent

In research
Alcatel-Lucent appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Alcatel-Lucent in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Alcatel-Lucent is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2016 mergers and acquisitions, Alcatel-Lucent, Companies based in Boulogne-Billancourt, so understanding it makes those chapters shorter.
In everyday life
Look for Alcatel-Lucent outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
