Ngaphambi kokusungulwa kwe-iPhone yokuqala, iifowuni zakwaNokia zazilawula intengiso, iifowuni ezazisivumela ukuba sabelane nabanye abavelisi bee-smartphone zelo xesha (zimbalwa eziseleyo namhlanje) bobabini abafowunelwa kunye neefoto ngendlela elula kakhulu kwaye ekhawulezayo (imifanekiso yayithatha indawo encinci kakhulu ngelo xesha).
Njengoko itekhnoloji yefowuni ephathwayo yavela, iiPDA (izandulela ze-iPhone) zafika kwaye zasivumela ukuba sabelane nabafowunelwa kunye nemifanekiso nezinye izixhobo. ngebluetooth ngaphandle kwemida. Kodwa iphone yafika yatshintsha yonke into.
Ngelo xesha (iminyaka elishumi yokuqala yee-2000s) savula kuphela iBluetooth yefowuni yethu / iPDA ukwabelana ngeefayile ukusukela oko. ukusetyenziswa kwakhe bekuphezulu kakhulu kwaye ibenefuthe kwibhetri yetheminali ukuba besihlala siyenza isebenze nokuba ibingadibanisi naso nasiphi na isixhobo.
Ngokuboniswa kwe-iPhone yokuqala ngo-2007, I-Apple ayizange ivumele iifayile okanye abafowunelwa ukuba babelane ngazo ngeBluetooth ngokungathi bonke abavelisi besixhobo bavumelekile. Sinokuyisebenzisa kuphela ukudibanisa izixhobo ezihambelana nobu buchwepheshe bonxibelelwano obuvumela ukuba zombini idatha kunye nelizwi zidluliselwe.
Nangona ukutyhubela iminyaka, itekhnoloji yeBluetooth ihambele phambili kakhulu, yongeza izinto ezintsha kunye nokuphucula isantya sokudlulisa, iApple inaloiqhubekile ngaphandle kokunika amandla okwabelana ngeefayile I-AirDrop (evezwe ngo-2011) ibe sisisombululo kule ngxaki, isisombululo sesiqingatha kuba sihambelana kuphela phakathi kwe-iPhones kunye ne-Macs kwaye ivumela naluphi na uhlobo lomxholo ukuba udluliselwe.
Imbali yeBluetooth: yenzeke njani?
Uphuhliso lwetekhnoloji yerediyo yonxibelelwano olufutshane (kamva yathiywa ngokuba yiBluetooth) Yaqala ngo-1989 nge-Ericson Mobile Ngenjongo yokuphuhlisa ii-headphones ezingasebenzi ngeengcingo, ekupheleni kweminyaka yoo-90, u-Ericsson wasebenzisana ne-IBM ukuphehlelela isixhobo esiphathwayo ngobu buchwepheshe bonxibelelwano.
Ngenxa yokuba ubukho babo kwimarike babungenobungqina, zombini iinkampani zagqiba yenza le teknoloji ibe ngumgangatho ovulekileyo ukuze nawuphi na umenzi akwazi ukuyidibanisa kwiimveliso zabo. NgoMeyi 1998, i-Bluetooth SIG yasungulwa kunye ne-IBM kunye ne-Ericsson njengabaseki. Kamva i-Intel, iNokia kunye neToshiba yongezwa kwaye ngaphezu kweminyaka kukho iinkampani ezingaphezu kwe-20.000 ezinxulumene neBluetooth SIG, inkampani ejongene nokuqhubeka nokuphuhlisa le teknoloji.
Ifowuni yokuqala Lowo weza kwintengiso ngetekhnoloji yeBluetooth yayiyi-Ericsson T-39 ngelixa ilaptop yokuqala ukuyiphumeza yayiyi-IBM ThinkPad A30. Zombini iimodeli zafikelela kwimarike yabathengi ngo-2001.
Ii-headphones zokuqala zebluetooth ifike kwimarike ngo-1999, imveliso eyaphumelela ibhaso Eyona Mbasa yeThekhnoloji yoMboniso ukusuka kwiCOMDEX, ibe yeyokuqala kwiimveliso ezininzi esinokuzifumana ngoku kwimarike.
Ukusetyenziswa kweteknoloji yeBluetooth
Itekhnoloji yeBluetooth isetyenziselwa ukudlulisa ulwazi phakathi kwezixhobo ezibini nangaphezulu ezisondeleleneyo ngokusebenzisa i-bandwidth ethile (i-2.4 ukuya kwi-2.48 GHz), ukusetyenziswa kwayo okuqhelekileyo ngoku kukudlulisa idatha kwii-headphone zeBluetooth kunye nezinye izixhobo.
Obu buchwephesha singayifumana okwangoku kwii-smartphones, izithethi, iitafile, abadlali bemultimedia, iinkqubo zerobhothi, iikhompyuter, iilaptops, ii-headphones kunye neewotshi ezihlakaniphile. Nangona ingaxhaphakanga kangako, sinokufumana iifowuni ezingenazingcingo ngamaxesha athile ngeBluetooth, iimodem kunye nezixhobo zokulinganisa ukusetyenziswa (iimitha zamanzi kunye nombane) kwimarike.
Iinguqulelo zeBluetooth kwii-iPhones
Bluetooth 2.0
Iinguqulelo ezimbini zokuqala ze-iPhone ezikhoyo kwiimarike, i-iPhone kunye ne-iPhone 3G, zeza kwimarike ngeBluetooth 2.0 (ekhutshwe kwi-2004). Le nguqulelo ibandakanye a izinga ledatha eliphuculweyo (EDR) enikezela ngesantya esiphezulu sokudlulisa idatha, ukufikelela kwi-2.1 Mbit / s, nangona kwi-theory inokufikelela kwi-3 Mbit / s.
Itekhnoloji ye-EDR nayo ibonelele nge ukusetyenziswa kwamandla okuphantsi, nangona ukunciphisa ukusetyenziswa xa kuthelekiswa nenguqulo yangaphambili (i-Bluetooth 1.2) yayingabalulekanga.
Bluetooth 2.1
I-iPhone 3GS kunye ne-iPhone 4 zifake i-Bluetooth version 2.1. I-Bluetooth 2.1 ifike kwimarike ngo-2007, eyona nto intsha kukuba ukudibanisa ngokukhawuleza nokukhuselekileyo (I-SSP yesifinyezo sayo ngesiNgesi).
Bluetooth 4.0
Ukusuka kwi-iPhone 4s ukuya kwi-iPhone 6, i-Apple iphumeze i-Bluetooth version 4.0 kwizixhobo zayo. Ngenguqulo 4.0, ngo-2010, yeza ilindelwe ukunciphisa ukusetyenziswa yale teknoloji kwizixhobo (BLE) ukongeza ukwandisa isantya sodluliselo idatha ukuya kuthi ga kwi-32 Mbit/s.
Bluetooth 4.2
Ngokusungulwa kwe-iPhone 4s, inguqulo ye-4.1 yeBluetooth yafika, inguqulelo eyagcinwa de kube yi-iPhone 7. Into entsha kuphela evela kule nguqulo ifumaneka ekuphunyezweni kwe-IPv6 protocol ye. vumela uqhagamshelo oluthe ngqo kwi-intanethi.
Bluetooth 5.0
I-Bluetooth 5.0 yeza kuluhlu lwe-iPhone kunye ne-iPhone 8, inguqulelo ekhoyo ngoku kwakhona kuluhlu lwe-iPhone 12. Le nguqulo ye-protocol yonxibelelwano yeBluetooth yafika kunye neempawu ezimbini eziphambili ezintsha: usasazo olubanzi (ukuya kwi-240 yeemitha) kunye ne-tIsantya sokuphatha ukuya kuthi ga kwi-50 Mbit / s.
