Iyo bluetooth gudzazwi imhando yeasina waya network yekuparadzira tekinoroji. Panguva iyoyo, isina waya tekinoroji anga aripo kwenguva yakareba, uye vamwe vacho vakatopinda padanho rakakura. Semuenzaniso, infrared tekinoroji inogona kuwanikwa mune akasiyana mutengi zvigadzirwa zvemagetsi senge midziyo yemumba, makomputa, nhare mbozha, uye PDAs. Iyo huru mukana weiyo infrared tekinoroji ndeye yakaderera mutengo. Asi zvikanganiso zvaro zvakare zvinouraya: kumhanya kunonoka, chinhambwe chipfupi, kuchengetedzeka kwakashata, kushomeka kwekusavhiringidza, saka tekinoroji yakasimba kwazvo isina waya inofanirwa kuberekwa nguva nenguva kuzadzisa chishuwo chevanhu cherusununguko, senge bluetooth gudzazwi tekinoroji.

Kubva mukuvandudzika kwenhoroondo ye bluetooth gudzazwi

Pane kukwikwidza kunotyisa mubluetooth amplifier chip musika, nekuti iyo chip chinhu chakakosha chinotakura shanduko yeiyi nyowani tekinoroji kuita zvigadzirwa. Kunyangwe zvigadzirwa zvebluetooth amplifier tekinoroji inogona kupinda mukati kugadzirwa kwakawanda kunoenderana nekuti iyo chip yekugadzira tekinoroji inogona kuramba ichikwira. Takatarisana nemusika uri kuwedzera, vazhinji vepasirose-kirasi semiconductor vagadziri vari kushingairira kuisa mari mukugadzirwa kwebluetooth gudzazwi machipisi kuti vagare munzvimbo dzakakwirira dzemusika. Vanozivikanwa vanogadzira nhare mbozha Nokia neNokia vakaburitsa maviri chip mhinduro anosangana neyazvino tekinoroji nhanho. Nokia's yekutanga bluetooth gudzazwi mahedhifoni uye bhaisikopo gudzazwi maserura vakavaka-mukati mavo avo ebluetooth gudzazwi machipisi. Mushure mezvo, Philips Semiconductors akambotora nzvimbo dzekuraira dzechip chip nekuda kwekubudirira kwayo kutora VLS1 Technology muna 1999. Motorola, Toshiba, Intel, uye IBM vanga vachiitawo mukuvandudza chip kana kutenga matekinoroji anoenderana nemarezinesi, asi hapana budiriro .

Muna 2002, Cambridge Silicon Radio (CSR) muUnited Kingdom yakaunza chaiyo CMOS single-chip solution (high-frequency component ten baseband controller) inonzi BlueCore (bluetooth amplifier core), uye yakabudirira kubatanidza mutsivi wayo vhezheni BlueCore 2 -Mutengo we Chip chekunze chakadonhera pasi peUS $ 5. Mukupedzisira, iyo bluetooth gudzazwi chigadzirwa chakasimuka. Kuwanikwa kwekambani kweBluetooth gudzazwi machipsi muna2002 kwakaenzana neinosvika 18% yemusika wese. Pakati pemidziyo yazvino yevashandisi vekupedzisira iyo inoenderana neyebluetooth gudzazwi 1.1 yakajairwa, 59% yakagadzirirwa zvigadzirwa zveCSR. CSR zvakare ine mukwikwidzi, Texas Instruments. Texas Instruments yakatangawo imwe-chip bluetooth gudzazwi muna 2002, iyo inodzorwa nekombuta panenge pa25mW, iri simba-rinoponesa. Ichi chigadzirwa chechi chip chinonzi BRF6100. Mutengo wekutenga zvakawanda unongova 3 kusvika ku4 US madhora. Texas Instruments iri kugadzirawo chip chinobatanidza bluetooth gudzazwi uye IEEE802.11b. Inofungidzirwa kuti kuunzwa kwechigadzirwa ichi kucharamba kuchideredza mutengo wemabluetooth amplifier machipisi. Kuvandudzwa kwetekinoroji yeWUSB kuchanyatso kuenda nenzira imwe chete yakaoma, uye mutengo unozoita dambudziko rekuvandudza reWUSB

Bluetooth gudzazwi inotsigira inowedzera uye yakawanda mabasa

Bluetooth amplifier chip maratidziro apfuura nematanho matatu ekuvandudza: 1.0, 1.1 uye yazvino vhezheni 1.2. Kutapurirana kwedata uye odhiyo kutapurirana ndiwo maviri akakosha mashandiro ebluetooth gudzazwi, kusanganisira chaiyo serial chiteshi chebluetooth gudzazwi, kufambisa faira, dial-up network, izwi gedhi, fax, headset, yemunhu manejimendi manejimendi manejimendi. Aya mabasa maviri ekutanga akawedzerwa. Izvo zvakakosha kuti uzive kuti mazhinji ebluetooth gudzazwi matomendi anogona kungopa chete mamwe emabasa aya. CSR's BlueCore 3bluetooth amplifier chip inoshandisa yazvino vhezheni 1.2, uye zvigadzirwa zvinoenderana hazvisati zvatanga pamwero mukuru. BlueCore 3 ine "inokurumidza kubatana" basa iyo inopfupisa nguva yekuzivisa pakati pebluetooth gudzazwi madhizaiksi kusvika isingasviki sekondi, uye inogona kuumbiridza frequency nguva panguva yekutaurirana kudzivirira kukanganiswa kweIEEE802.11b.

Kune mamwe mabasa ekuvandudza mhando yekutapurirana kweinzwi uye kubatanidza mamwe madivhuru ekuwedzera ebluetooth. Chii chinonakidza ndechekuti chip Hardware inoenderana neshanduro 1.1 haidi kuchinjwa, ingo zorodza iyo firmware (firmware, yakafanana neiyo mamaboard BIOS) kuwedzera mabasa ari pamusoro. Uye zvakare, iyo yega musimboti simba rekushandisa iri 18% pasi pane BlueCore 2-Kunze. Zvinoenderana neruzivo rwakaburitswa, tekinoroji yeWUSB ine zvakawanda zvakanakira hunyanzvi kupfuura bluetooth gudzazwi tekinoroji, asi kusimudzira kwekushandisa ndiko kukunda kwehunyanzvi hweWUSB.
