Bell Labs [b] is an American industrial research and development (R&D) company, currently operating as a subsidiary of Finnish technology company Nokia.With a long history, Bell Labs is credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages ...
The Bell Labs Holmdel Complex, in Holmdel Township, Monmouth County, New Jersey, United States, functioned for 44 years as a research and development facility, initially for the Bell System and later Bell Labs. [3] The centerpiece of the campus is an Eero Saarinen–designed structure that served as the home to over 6,000 engineers and ...
Instead, he assembled a team of young scientists and engineers, some from other parts of Bell Laboratories, and set about designing a new type of crystal-growth system that could produce single-crystal silicon boules, at that time a difficult prospect given silicon's high melting point.
The Model V was among the early [2] electromechanical [3] general purpose computers, [4] [5] [6] designed by George Stibitz and built by Bell Telephone Laboratories, operational in 1946. Only two machines were built: first one was installed at National Advisory Committee for Aeronautics (NACA, later NASA), the second (1947) at the US Army’s ...
A typical volume of Bell System Practices from the 1970s. The Bell System Practices (BSPs) is a compilation of technical publications which describes the best methods of engineering, constructing, installing, and maintaining the telephone plant of the Bell System under direction of AT&T and Bell Telephone Laboratories.

As a result, Alcatel-Lucent dismantled the last 1AESS lab at the Naperville Bell Labs location in 2015, and announced the discontinuation of support for the 1AESS. [9] [10] In 2017, AT&T completed the removal of remaining 1AESS systems by moving customers to other newer technology switches, typically with Genband switches with TDM trunking only.
TD-2 was a microwave relay system developed by Bell Labs and used by AT&T to build a cross-country network of repeaters for telephone and television transmission. The same system was also used to build the Canadian Trans-Canada Skyway system by Bell Canada , and later, many other companies in many countries to build similar networks for both ...
The Number Five Crossbar Switching System (5XB switch) is a telephone switch for telephone exchanges designed by Bell Labs and manufactured by Western Electric starting in 1947. It was used in the Bell System principally as a Class 5 telephone switch in the public switched telephone network (PSTN) until the early 1990s, when it was replaced ...
