LOGO
One source inside Lucent says that the logo is
actually a Zen Buddhist symbol for "eternal
truth", the Enso, turned 90 degrees and modified.
Another source says it represents the mythic
ouroboros, a snake holding its tail in its mouth.

29
Divisions

• Lucent is divided into several core groups
• Network Solutions Group
• serves landline/cellular telephone service
  providers by providing equipment other
  solutions necessary to provide telephone service,
  including networking equipment

30
Divisions

• Lucent Worldwide Services (LWS)
• a division with customers around the world that
  provides network services to telecom companies
  and business. LWS's clients include ATT
  Verizon.

31
Divisions

• Bell Labs
• created in 1925 as the RD firm of the Bell
  System. It was an ATT subsidiary set up as dual
  ownership by ATT and Western Electric, the
  manufacturing arm of ATT. Bell Labs has
  accumulated over 31,000 patents in its existence,
  some of which include development of the LED and
  discovery of the measure of sound.

32
Bell Labs
33

• Bell Laboratories is the research organization of
  
• Alcatel-Lucent and previously the United
  States
• Bell System.
• Bell Laboratories is headquartered at Murray
  Hill,
• New Jersey, in the USA, and has research and
• development facilities throughout the world.

34
Origin and historical locations
35
Discoveries and Developments

images of Herbert Hoover
1928 the thermal noise in a resistor was first
measured by John B. Johnson with Harry Nyquist
During the 1920s, the one-time pad cipher was
invented by Gilbert Vernam and Joseph Mauborgne
at the laboratories Bell's Claude Shannon later
proved that it was unbreakable.
37
