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.
