Isikhulisi seBluetooth luhlobo lwetekhnoloji yokuhambisa inethiwekhi ngaphandle kwamacingo. Ngelo xesha, itekhnoloji engenazingcingo ibisoloko ikho ixesha elide, kwaye ezinye zazo ziye zangena kwinqanaba lokuvuthwa. Umzekelo, itekhnoloji ye-infrared inokufumaneka kwiimveliso ezahlukeneyo zabathengi ezinje ngezixhobo zasekhaya, iikhompyuter, iifowuni eziphathwayo kunye nee-PDAs. Olona ncedo lukhulu kubuchwephesha be-infrared lixabiso eliphantsi. Kodwa ukusilela kwayo kuyabulala: isantya esicothayo, umgama omfutshane, ukhuseleko oluphantsi, ukungahambelani nokuphazamiseka, ubuchwepheshe obunamandla obungenazingcingo kufuneka buzalwe amaxesha ngamaxesha ukuhlangabezana nomnqweno wabantu wenkululeko, njenge-bluetooth amplifier technology.

Ukusuka kuphuhliso lwembali lwebluetooth yesikhulisi

Kukho ukhuphiswano olunobukrakra kwimakethi ye-chip amplifier ye-bluetooth, kuba i-chip yinto ebalulekileyo yokuhambisa itekhnoloji entsha ye-IT kwiimveliso. Nokuba iimveliso zetekhnoloji yebluetooth yesikhulisi inokungena ngokwenyani kwimveliso yobunzima kuxhomekeke ekubeni itekhnoloji yokuvelisa ye-chip inokuqhubeka. Ukujongana nentengiso ekhulayo, uninzi lwabenzi beesemiconductor abakumgangatho wehlabathi batyale imali kwimveliso yeetshipsi zebluetooth zeetshipsi ukuze bafumane indawo ephezulu yokuthengisa. Abenzi abaziwayo beefowuni eziphathwayo u-Nokia kunye no-Nokia bavelise izisombululo ezimbini ze-chip ezihlangabezana nenqanaba lobuchwephesha. Ii-headsets ze-bluetooth zesikhulisi se-bluetooth zakuqala kunye neefowuni zeBluetooth zesikhulisi ezakhele ezazo iitshipsi zebluetooth. Emva koko, uPhilips Semiconductors bakha bahlala kwiindawo eziphakamileyo zokubonelela nge-chip ngenxa yokuthatha ngempumelelo iTekhnoloji ye-VLS1 ngo-1999. IMotorola, iToshiba, i-Intel, kunye ne-IBM nazo ziye zabandakanyeka kuphuhliso lwe-chip okanye zathenga itekhnoloji ehambelana neelayisensi, kodwa akukho mpu melelo. .

Ngo-2002, iCambridge Silicon Radio (CSR) e-United Kingdom yazisa isisombululo esinyani se-CMOS (isiphathamandla esiphakamileyo seshumi somlawuli we-baseband) esibizwa iBlueCore (ibluetooth amplifier core), kwaye yadibanisa ngempumelelo inguqulelo yomlandeli wayo iBlueCore 2 -Ixabiso i-Chip yangaphandle yehle yaya kuthi ga ngaphantsi kwe-US $ 5. Ekugqibeleni, imveliso yesikhulisi seBluetooth iye yahamba. Ukubonelelwa kwenkampani ngeetshipsi zebluetooth chips ngo-2002 zabalelwa malunga ne-18% yentengiso iyonke. Phakathi kwezixhobo ezikhoyo zabasebenzisi bokugqibela ezihambelana ne-bluetooth amplifier 1.1 standard, i-59% ixhotyiswe ngemveliso ye-CSR. I-CSR ikwanomntu okhuphisana naye, iTexas Instruments. Izixhobo zaseTexas zikwasungule i-single-chip bluetooth amplifier ngo-2002, elawulwa yikhompyuter malunga ne-25mW, egcina amandla kakhulu. Le mveliso ye-chip ibizwa ngokuba yi-BRF6100. Ixabiso lokuthengwa kwesambuku li-3 ukuya kwi-4 yeedola zaseMelika. Izixhobo zaseTexas zikwakhulisa i-chip edibanisa i-bluetooth amplifier kunye ne-IEEE802.11b. Kuqikelelwa ukuba ukwaziswa kwale mveliso kuya kulinciphisa ngakumbi ixabiso leetshipsi zebluetooth. Ukuphuhliswa kwetekhnoloji yeWUSB ngokuqinisekileyo kuya kudlula kwikhosi efanayo enzima, kwaye ixabiso liya kuba yingxaki yophuhliso lweWUSB.

Isikhulisi seBluetooth sixhasa imisebenzi engakumbi nangakumbi

Ukucaciswa kwe-chip yokukhulisa iBluetooth kudlule kumanqanaba amathathu ophuhliso: i-1.0, 1.1 kunye nohlobo lwamva nje lwe-1.2. Ukuhanjiswa kwedatha kunye nokuhanjiswa komsindo zizinto ezimbini ezisisiseko ze-bluetooth amplifier, kubandakanya izibuko le-bluetooth, ukuhanjiswa kwefayile, uthungelwano lokufowunela, isango lelizwi, ifeksi, iseti yentloko, ungqamaniso lolawulo lolwazi lomntu, uthungelwano lwebluetooth yesikhulisi, izixhobo ze-ergonomic, njl. Le misebenzi mibini isisiseko iyandiswa. Kubalulekile ukuba uqaphele ukuba izixhobo ezininzi zokukhulisa ibluetooth zinokubonelela kuphela ngale misebenzi. I-CSR's BlueCore 3bluetooth amplifier chip isebenzisa inguqulelo yamva nje ye-1.2, kwaye iimveliso zayo ezihambelanayo azikaziswanga kwinqanaba elikhulu. IBlueCore 3 inomsebenzi "wokunxibelelana ngokukhawuleza" owenza ukuba ixesha lokuchongwa lifumaneke phakathi kwezixhobo ze-bluetooth ze-amplifier ukuya ngaphantsi komzuzwana omnye, kwaye inokulungelelanisa ngokukhawuleza ngexesha lonxibelelwano ukunqanda ukuphazamiseka kwe-IEEE802.11b.

Kukwakho nemisebenzi yokuphucula umgangatho wokuhambisa isandi kunye nokunxibelelana nezixhobo ze-bluetooth zesikhulisi. Into enomdla kukuba i-chip ye-chip esekwe kuhlobo lwe-1.1 ayifuni kutshintshwa, vele uvuselele i-firmware (i-firmware, efanayo nebhodi yomama ye-BIOS) ukongeza le misebenzi ingentla. Ukongeza, ukusetyenziswa kwamandla okusisiseko konke yi-18% isezantsi kuneBlueCore 2-Ngaphandle. Ngokwengcaciso epapashiweyo, itekhnoloji ye-WUSB ineenzuzo zobuchwephesha ngakumbi kuneetekhnoloji ze-bluetooth amplifier, kodwa ukukhuthazwa kwezicelo yeyona ngxaki iphambili yetekhnoloji yeWUSB.
