Bell Labs
Bell labs was incorporated in 1925 as an AT&T subsidiary under the name of Bell Telephone Laboratories, Inc. Bells primary task was to develop telecommunications equipment and systems manufactured by AT&T. From it's start, Bell labs has produced thousands of scientific and engineering innovations that helped shape the modern technology we have today. They are still making breakthroughs every year on current technology and future tech that they are trying to bring to the world. -
Hearing Aids
the first Bell Labs amplified hearing aid was built in 1922. It was very large, weighing over 200 pounds, but it worked well and could reproduce sound in stereo. The 37-A Audiphone hearing aid, developed in 1928, was a significant improvement using a portable amplifier with miniature vacuum tubes. -
Artificial Larnyx
Bell labs developed a device that made speech possible for people whose larnyxes have been surgically removed. -
Karl Jansky
After having earned a BS in physics from the University of Wisconsin-Madison in 1927, Jansky joins Bell Labs as a radio engineer. Tasked with determining the cause of radio static on shortwave radio transmissions for transatlantic transmissions, he goes on to discover electrical disturbances of cosmic origin radio waves emanating from the center of the galaxy. -
Binary Digital Computer
The first electrical Digital computer uses telephone switches and electro- mechanical relays that could be operated from a distance over a telegraph circuit. -
Russell Oil
An electrochemist, Russell Ohl discovered the n- and p-type regions in silicon and the photoelectric effect in p-n junctions. These discoveries played a crucial role in the ultimate development of the transistor and the solar cell. He was a pioneer in ion implantation, conducting the first successful experiment implanting ions in silicon to improve device characteristics. -
Advanced Radar
In the late summer of 1940, two physicists from the University of Birmingham came to Bell Labs with a prototype for a highly effective cavity magnetron in search of a technical solution for a manufacturable design. Within a year, the device was in mass production. Radar technology was a primary focus at Bell Labs in the 1940s. -
Mobile Phone Service
The first commercial mobile telephone service, developed by Bell Labs, begins in 1946. At most, three subscribers per city can make calls at one time, and each call requires the use of an operator. -
Transistor
Developed as a replacement for vacuum tubes, the tiny device later revolutionizes the entire electronics industry. In 1956, the Nobel Prize in Physics was awarded jointly to William Bradford Shockley, John Bardeen and Walter Houser Brattain "for their researches on semiconductors and their discovery of the transistor effect." -
John Tukey
John Tukey's contributions in Exploratory Data Analysis are fixtures in contemporary introductory and advanced statistical texts. In 1965, together with James Cooley, he introduced the analytical tool known as fast Fourier transform, which remains a ubiquitous technique for understanding waveforms in fields from astrophysics to electrical engineering. -
Lasers
Bell Labs researchers invent lasers — light amplification by stimulated emission of radiation — that revolutionize not only the communications industry, but also materials processing, optical scanning, medicine, energy research and surveying. -
UNIX OS
A simple but elegant time-share software system for minicomputers, variations of UNIX can be found in most of the world's Internet services and cell phones. -
C Langauge
Arguably the most widely used programming language of all time, the C programming language, developed by Dennis Ritchie which allows for the coding of applications that had previously been coded in assembly language. -
Atom Trapping
Bell Labs’ Steven Chu and his colleagues use laser light to slow and manipulate atoms, providing an insight into quantum mechanics. Chu and his collaborators win a Nobel Prize for this work in 1997. -
Functional MRI
In a seminal 1990 article, Bell Labs researcher Seiji Ogawa and colleagues laid the foundation for using magnetic resonance imaging and the variation in blood oxygenation level associated with brain activity as a way for non-invasively mapping brain functions. This method, called functional MRI, is widely used for medical diagnosis and in neurological research. -
HDTV Standards
Bell Labs researchers jointly pioneer digital television and HD (high definition) TV in the United States, an effort that included General Instrument, Philips, Sarnoff, Thomson, Zenith, and MIT. -
Softrouter
This type of routing architecture separates control elements from forwarding elements. It permits development of a programmable, open network infrastructure allowing easier deployment of new services that make use of exposed network capabilities. Control plane functions are located on general purpose servers close to the forwarding elements. This makes scaling much easier than adding control card hardware to a conventional router. -
Active Antenna Arrays
Bell Labs developed active antenna arrays for both fixed and mobile wireless systems, with smart steerable beam antennae sending pencil-thin beams directly to the receiver. This method saves energy, minimizes interference, and allows reuse of the same frequency in a given coverage area, drastically improving spectrum efficiency. Coverage improves as much as 70% and data throughput capacity by 100%, boosting network capacity by up to 300%. -
World’s first live end-to-end 5G lab
The Future X Lab in Murray Hill, New Jersey integrates every part of the network and not on paper or through prototype or trial, but live and end to end, with full network slicing under seamless digital operations control. -
