Kehityshistoria
TheBellTelephoneLaboratoryorBellLaboratorywasoriginallyaresearchanddevelopmentorganizationintheBellsystemthatengagedintelecom-relatedtechnologiesincludingtelephoneexchanges,telephonecables,andsemiconductors.
In1925,whenAT&Tpresident,WalterGifford(WalterGifford).AcquiredtheresearchdepartmentofWesternElectronicsCorporationandestablishedanindependententitycalled"BellTelephoneLaboratories."AT&TandWesternElectronicseachown50%ofthecompany.
TheworkofBellLabscanberoughlydividedintothreecategories:basicresearch,systemengineeringandapplicationdevelopment.Inbasicresearch,heismainlyengagedinthebasictheoreticalresearchoftelecommunicationstechnology,includingmathematics,physics,materialscience,behavioralscienceandcomputerprogrammingtheory.Systemengineeringmainlystudiesthehighlycomplexsystemsthatconstitutetelecommunicationnetworks.ThedevelopmentdepartmentisthelargestdepartmentofBellLabsandisresponsiblefordesigningtheequipmentandsoftwarethatmakeuptheBellSystemtelecommunicationsnetwork.
After1984,inaccordancewiththeUSgovernment'sagreementtospinoffAT&T,BellcorewassplitfromBellLabs.BellcoreprovidesunifiedresearchanddevelopmentservicesforaseriesofsmallBellcompaniesafterthespin-off.
In1996,BellLabsandAT&T'sequipmentmanufacturingdepartmentseparatedfromAT&TandbecameLucentTechnologies.AT&Tretainedasmallnumberofresearcherstobecomeitsresearchinstitution-AT&TLabs.

In1933,KarlJanskydiscoveredthatthecenteroftheMilkyWaywascontinuouslyemittingradiowavesbystudyingelectrostaticnoiseinlong-distancecommunications.Thisradiowavewascalled3Kbackgroundradiation.Throughthisresearch,radioastronomywasestablished.
In1947,BellLabsinventedthetransistor.Participatinginthisresearch,JohnBardeen,WilliamShockley,andWalterHouserBrattainwontheNobelPrizeinPhysicsin1956.
