I-amplifier ye-bluetooth uhlobo lobuchwepheshe bokudlulisa inethiwekhi engenantambo. Ngaleso sikhathi, ubuchwepheshe obungenazintambo bekunesikhathi eside bukhona, futhi abanye babo sebengene esigabeni esivuthiwe. Isibonelo, ubuchwepheshe be-infrared bungatholakala kwimikhiqizo eyahlukene yabathengi efana nezinto zasekhaya, amakhompyutha, izingcingo eziphathwayo, nama-PDA. Inzuzo enkulu ngobuchwepheshe be-infrared izindleko zayo eziphansi. Kepha ukushiyeka kwayo nakho kuyabulala: isivinini esisheshayo, ibanga elifushane, ukuphepha okuncane, ukungahambelani okuphansi, ngakho-ke ubuchwepheshe obunamandla obungenantambo kufanele buzalwe ngezikhathi ezithile ukuhlangabezana nesifiso sabantu senkululeko, njengobuchwepheshe be-bluetooth amplifier.

Kusukela ekuthuthukisweni komlando kwe-bluetooth amplifier

Kukhona ukuncintisana okunzima emakethe ye-bluetooth amplifier chip, ngoba i-chip iyisithwali esibalulekile sokuguqulwa kobuchwepheshe obusha be-IT bube yimikhiqizo. Ukuthi imikhiqizo ye-bluetooth amplifier technology ingangena ngempela yini ekukhiqizweni ngobuningi kuya ngokuthi ubuchwepheshe bokukhiqiza i-chip bungaqhubeka yini. Babhekene nemakethe echumayo, abakhiqizi abaningi bama-semiconductor abasezingeni lomhlaba batshala imali ngentshiseko ekukhiqizeni ama-chip e-bluetooth amplifier ukuze badle izindawo eziphakeme kakhulu emakethe. Abenzi bomakhalekhukhwini abaziwayo iNokia neNokia bakhiqize izixazululo ezimbili ze-chip ezihlangabezana nezinga lobuchwepheshe elikhona manje. Amahedisethi wesikhulisi se-bluetooth asekuqaleni akwa-Ericsson namaselula wesikhulisi se-bluetooth azakhele owawo ama-chip e-bluetooth amplifier. Ngemuva kwalokho, abakwaPhilips Semiconductors bake bahlala ezindaweni eziphakeme zokuhlinzekwa kwe-chip ngenxa yokuthatha ngempumelelo kwayo i-VLS1 Technology ngo-1999. I-Motorola, iToshiba, i-Intel, ne-IBM nabo babambe iqhaza ekuthuthukiseni i-chip noma bathenga ubuchwepheshe obuhambisana namalayisense, kepha akukho ukuphumelela .

Ngo-2002, iCambridge Silicon Radio (CSR) e-United Kingdom yethula isixazululo sangempela se-CMOS single-chip (high-frequency component ten baseband controller) esibizwa ngeBlueCore (i-bluetooth amplifier core), futhi yahlanganisa ngempumelelo inguqulo yayo eyalandela iBlueCore 2 -Intengo ye- i-chip yangaphandle iwele ngaphansi kwe-US $ 5. Ekugcineni, umkhiqizo wesikhulisi se-bluetooth uhambe. Ukuphakelwa kwenkampani ama-bluetooth amplifier chips ngo-2002 kwabalelwa ku-18% wemakethe isiyonke. Phakathi kwemishini yamanje yabasebenzisi bokugcina ehambisana ne-bluetooth amplifier 1.1 standard, ama-59% anemikhiqizo ye-CSR. I-CSR nayo inembangi yayo, iTexas Instruments. ITexas Instruments iphinde yethula i-single-chip bluetooth amplifier ngo-2002, elawulwa yikhompyutha cishe ku-25mW, ekonga kakhulu amandla. Lo mkhiqizo we-chip ubizwa nge-BRF6100. Intengo yokuthengwa kwenqwaba ingamadola amathathu kuya kwamane e-US. ITexas Instruments ibuye ithuthukise i-chip ehlanganisa i-bluetooth amplifier ne-IEEE802.11b. Kulinganiselwa ukuthi ukwethulwa kwalo mkhiqizo kuzoqhubeka nokunciphisa intengo yama-chips e-bluetooth amplifier. Ukuthuthukiswa kobuchwepheshe be-WUSB nakanjani kuzodlula enkambweni efanayo enzima, futhi intengo izoba yinkinga yokuthuthuka ye-WUSB.

Isikhulisi se-Bluetooth sisekela imisebenzi eyanda

Ukucaciswa kwe-chip ye-Bluetooth amplifier chip kudlule ezigabeni ezintathu zokuthuthuka: i-1.0, i-1.1 nenguqulo yakamuva ye-1.2. Ukudluliswa kwedatha nokudluliswa komsindo kuyimisebenzi emibili eyisisekelo ye-bluetooth amplifier, kufaka phakathi imbobo ye-serial ye-bluetooth amplifier, ukudluliswa kwefayela, inethiwekhi yokudayela, isango lezwi, ifeksi, ihedisethi, ukuvumelanisa kwemininingwane yomuntu siqu, inethiwekhi ye-bluetooth amplifier, imishini ye-ergonomic, njll. Le misebenzi emibili eyisisekelo iyanwetshwa. Kumele uqaphele ukuthi amadivayisi amaningi we-bluetooth amplifier anganikeza kuphela eminye yale misebenzi. I-CSR's BlueCore 3bluetooth amplifier chip isebenzisa inguqulo yakamuva ye-1.2, futhi imikhiqizo yayo ehambelanayo ayikethulwa ngezinga elikhulu. IBlueCore 3 inomsebenzi "wokuxhuma okusheshayo" ofushanisa isikhathi sokuhlonza phakathi kwamadivayisi we-bluetooth amplifier kungaphansi kwesekhondi elilodwa, futhi ingagxuma imvamisa ngesikhathi sokuxhumana ukugwema ukuphazamiseka kwe-IEEE802.11b.

Kukhona nemisebenzi yokwenza ngcono ikhwalithi yokudlulisa umsindo nokuxhuma amadivayisi amaningi we-bluetooth amplifier. Okuthokozisayo ukuthi i-chip hardware esekwe enguqulweni 1.1 ayidingi ukushintshwa, vele uvuselele i-firmware (firmware, efana ne-motherboard BIOS) ukufaka imisebenzi engenhla. Ngaphezu kwalokho, wonke amandla wokusebenzisa amandla angaphansi kwe-18% kune-BlueCore 2-External. Ngokwolwazi olushicilelwe, ubuchwepheshe be-WUSB bunezinzuzo ezingaphezulu kwezobuchwepheshe kune-bluetooth amplifier technology, kepha ukukhuthazwa kwezinhlelo zokusebenza kungukuvinjelwa kwangempela kobuchwepheshe be-WUSB.
