Bell Labs was founded in 1925 by AT&T President Walt Kieferd after taking over the research department of Western Electronics Corporation. In 1996, it became the research and development department of Lucent Technologies, and in 2016, it was acquired by Nokia. The work is broadly divided into three categories: basic research, systems engineering, and application development. In terms of basic research, he is mainly engaged in the basic theoretical research of telecommunications technology, including mathematics, physics, materials science, behavioral science and computer programming theory. Systems engineering mainly studies the highly complex systems that make up telecommunications networks. The Development Division is the largest division at Bell Labs and is responsible for designing the equipment and software that make up Bell Systems' telecommunications network.
Bell Labs is one of the few R&D institutions in industry. Research and development is divided into three stages: one is Bell Labs' own invention or innovation, and the other is to evolve and update its own products. The other is to go to Europe and other regions to absorb new technologies and new products through mergers and acquisitions. Bell Labs in the United States is the birthplace of many major inventions such as transistors, lasers, solar cells, light-emitting diodes, digital switches, communication satellites, electronic digital computers, C languages, UNIX operating systems, cellular mobile communication equipment, long-distance television transmission, simulation languages, audio movies, stereo recordings, and communication networks.
Basic research underpins nokia bell labs' mission, laying the foundation for the digital world of modern life, the software that powers it, and the communications networks that connect it. Today, Bell Labs' research follows many different trajectories, though the goal remains the same: to design the technology that will have the most lasting impact on the service providers, businesses, and industries nokia serves.
