Whenyouusecomputers,entertainmentsystemsortelephones,thevariouspiecesandpartsofthesystemsmakeupacommunityofelectronicdevices.Thesedevicescommunicatewitheachotherusingavarietyofwires,cables,radiosignalsandinfraredlight(红外线)beams,andanevengreatervarietyofconnectorsandplugs.

Theartofconnectingthingsisbecomingmoreandmorecomplexeveryday.AndBluetoothhasnowbecomeanewpopularmethodofconnectingdevicesthatcanstreamlinetheprocess.ABluetoothconnectioniswirelessandautomatic,andittakessmall-areanetworkingtothenextlevelbyremovingtheneedforuserinterventionandkeepingtransmissionpowerextremelylowtosavebatterypower.

BluetoothOperation

Bluetoothnetworkingtransmitsdatavialow-powerradiowaves.Itcommunicatesonafrequencyof2.45gigahertz(千兆赫)(actuallybetween2.402GHZand2.480GHz,tobeexact).Thisfrequencybandhasbeensetasidebyinternationalagreementfortheuseofindustrial,scientificandmedicaldevices(ISM).

Anumberofdevicesthatyoumayalreadyusetakeadvantageofthissameradio-frequencyband.Babymonitors(微型监视器),garage-dooropenersandthenewestgenerationofcordlessphones(无绳电话)allmakeuseoffrequenciesintheISMband.

OneofthewaysBluetoothdevicesavoidinterferingwithothersystemsisbysendingoutveryweaksignalsofabout1milliwatt.Bycomparison,themostpowerfulcellphonescantransmitasignalof3watts.ThelowpowerlimitstherangeofaBluetoothdevicetoabout10meters(32feet),cuttingthechancesofinterferencebetweenyourcomputersystemandyourportabletelephoneortelevision.Evenwiththelowpower,Bluetoothdoesn'trequirelineofsightbetweencommunicatingdevices.Thewallinyourhousewon'tstopaBluetoothsignal,makingthestandardusefulforcontrollingseveraldevicesindifferentrooms.

Bluetoothcanconnectuptoeightdevicessimultaneously.Withallofthosedevicesinthesame10-meter(32-foot)radius,youmightthinkthey'dinterferewithoneanother,butit'sunlikely.Bluetoothusesatechniquecalledspread-spectrum(扩展频谱)frequencythatmakesitrareformorethanonedevicetobetransmittingonthesamefrequencyatthesametime.Inthistechnique,adevicewilluse79individual,randomlychosenfrequencieswithinadesignatedrange,changingfromonetoanotheronaregularbasis.InthecaseofBluetooth,thetransmitterschangefrequencies1,600timeseverysecond,meaningthatmoredevicescanmakefulluseofalimitedsliceoftheradiospectrum.SinceeveryBluetoothtransmitter(传输设备)usesspread-spectrumtransmittingautomatically,it'sunlikelythattwotransmitterswillbeonthesamefrequencyatthesametime.ThissametechniqueminimizestheriskthatportablephonesorbabymonitorswilldisruptBluetoothdevices,sinceanyinterferenceonaparticularfrequencywilllastonlyatinyfractionofasecond.
