Ngaphambi kokwethulwa kwe-iPhone yokuqala, izingcingo zakwaNokia beziphethe imakethe, izingcingo ezisivumele ukuthi sabelane nabanye abakhiqizi be-smartphone bangaleso sikhathi (bambalwa abasele namuhla) bobabili oxhumana nabo nezithombe ngendlela elula kakhulu futhi esheshayo (izithombe zithathe isikhala esincane kakhulu ngaleso sikhathi).
Njengoba ubuchwepheshe beselula buvela, ama-PDAs (abangaphambi kwe-iPhone) afika futhi asivumela ukuthi sabelane nabanye oxhumana nabo nezithombe namanye amadivayisi nge-bluetooth ngaphandle kwemingcele. Kodwa i-iPhone ifikile yonke into yashintsha.
Ngaleso sikhathi (iminyaka eyishumi yokuqala ka-2000) besivula i-bluetooth yefoni yethu / i-PDA kuphela ukuze sabelane ngamafayela kusukela lapho ukusetshenziswa kwabo kwakuphezulu kakhulu futhi kuthinte ibhethri le-terminal uma besiyisebenzisa njalo noma ngabe belingahlotshaniswa nanoma iyiphi idivayisi.
Ngokwethulwa kwe-iPhone yokuqala ngo-2007, I-Apple ayivumanga ukuthi kwabiwe amafayela noma oxhumana nabo nge-bluetooth njengoba kuvunyelwe yibo bonke abenzi bedivayisi. Singayisebenzisa kuphela ukuxhuma amadivayisi ahambisanayo nalobu buchwepheshe bokuxhumana obuvumela ukudlulisa kokubili idatha nezwi.
Ngaphandle kokuthi eminyakeni edlule, ubuchwepheshe be-bluetooth buqhubekele phambili kakhulu, bengeza ukusebenza okusha nokwenza ngcono isivinini sokudlulisa, i-Apple hkulandelwe ngaphandle kokunikeza amandla okwabelana ngamafayela ukuba yi-AirDrop (eyethulwe ngo-2011) isisombululo sale nkinga, isisombululo sesigamu ngoba sisebenza kuphela phakathi kwama-iPhones nama-Mac futhi sivumela noma yiluphi uhlobo lokuqukethwe ukuthi ludluliswe.
Umlando we-Bluetooth: kwenzeka kanjani?
Ukuthuthukiswa kobuchwepheshe bomsakazo obuxhuma amafushane (obubizwa nge-bluetooth kamuva) kwaqala ngo-1989 ngabakwaNokia Mobile ngenhloso yokwakha amahedisethi angenazintambo. Ekupheleni kweminyaka yama-90s Ericsson basebenzisane ne-IBM ukwethula umakhalekhukhwini ngalobu buchwepheshe bezokuxhumana.
Ngoba ukuba khona kwabo emakethe kwakungubufakazi kuphela, zombili izinkampani zanquma yenza lobu buchwepheshe bube yindinganiso evulekile ukuze noma yimuphi umkhiqizi akwazi ukukuhlanganisa nemikhiqizo yabo. NgoMeyi 1998, i-Bluetooth SIG yethulwa nge-IBM ne-Ericsson njengabasunguli. Kamuva, kwanezelwa i-Intel, iNokia neToshiba kanti eminyakeni edlule kunezinkampani ezingaphezu kuka-20.000 XNUMX ezihambisana neBluetooth SIG, okuyinkampani ephethe ukuqhubeka nokwenza lobu buchwepheshe.
Ucingo lokuqala eze emakethe ngobuchwepheshe be-bluetooth bekuyi-Nokia T-39 ngenkathi ilaptop yokuqala ukuyisebenzisa bekuyi-IBM ThinkPad A30. Zombili lezi zinhlobo zifike emakethe yabathengi ngo-2001.
Amahedfoni we-bluetooth wokuqala yangena emakethe ngo-1999, umkhiqizo owawina lo mklomelo Umklomelo Ohamba Phambili Wezobuchwepheshe we-COMDEX, ube ngowokuqala kwemikhiqizo eminingi esingayithola manje emakethe.
Ukusetshenziswa kobuchwepheshe be-Bluetooth
Ubuchwepheshe be-Bluetooth busetshenziselwa dlulisa imininingwane phakathi kwamadivayisi amabili noma ngaphezulu asondelene ngokusebenzisa umkhawulokudonsa othize (2.4 kuya ku-2.48 GHz) ukusetshenziswa kwawo okuvame kakhulu namuhla ukudlulisa idatha kumahedisethi e-bluetooth nakwamanye amadivayisi.
Lobu buchwepheshe singayithola actualmente en smartphones, altavoces, tablets, reproductores multimedia, sistemas de robóticos, ordenadores, portátiles, audífonos y relojes inteligentes. Aunque es menos habitual, también podemos encontrar en el mercado algún que otro teléfono inalámbrico con Bluetooth, módems y dispositivos de medición de consumo (contadores de agua y luz).
Izinhlobo ze-Bluetooth kuma-iPhones
I-Bluetooth 2.0
Izinhlobo ezimbili zokuqala ze-iPhone ezitholakala emakethe, i-iPhone ne-iPhone 3G, zingene emakethe ngeBluetooth 2.0 (ekhishwe ngo-2004). Le nguqulo ifake ifayela le- isilinganiso sedatha esithuthukisiwe (I-EDR ngesifinyezo sayo esiNgisini) enikezela ngejubane eliphakeme lokudluliswa kwedatha elifinyelela ku-2.1 Mbit / s yize ithiyori lingafinyelela ku-3 Mbit / s.
Ubuchwepheshe be-EDR babuye banikela nge- ukusetshenziswa kwamandla okuphansi, yize ukwehliswa kokusetshenziswa kuqhathaniswa nenguqulo yangaphambilini (i-bluetooth 1.2) kwakungabalulekanga kangako.
I-Bluetooth 2.1
I-iPhone 3GS ne-iPhone 4 ifake inguqulo 2.1 ye-bluetooth. I-Bluetooth 2.1 yangena emakethe ngo-2007, ubusha bayo obukhulu kungumsebenzi we ukubhanqa okusheshayo nokuphephile (I-SSP isichazamazwi sayo esiNgisini).
I-Bluetooth 4.0
Kusukela kuma-iPhone 4s kuya ku-iPhone 6, i-Apple isebenzise i-bluetooth version 4.0 kumadivayisi ayo. Ngenguqulo 4.0, ngo-2010, okulindelwe kwafika ukunciphisa ukusetshenziswa lobu buchwepheshe kumadivayisi (BLE) ngaphezu kwe nweba isivinini sokudlulisa idatha efinyelela kuma-32 Mbit / s.
I-Bluetooth 4.2
Ngokwethulwa kwe-iPhone 4s, inguqulo 4.1 ye-bluetooth ifikile, inguqulo eyahlala kwaze kwafika i-iPhone 7. Okuwukuphela kwento entsha evela kule nguqulo itholakale ekusetshenzisweni kwenqubo ye-IPv6 vumela ukuxhumeka okuqondile ku-inthanethi.
I-Bluetooth 5.0
I-Bluetooth 5.0 ifike ebangeni le-iPhone ne-iPhone 8, inguqulo okwamanje esezingeni le-iPhone 12. Le nguqulo yephrothokholi yokuxhumana ye-bluetooth ifike nezinto ezintsha ezimbili eziyinhloko: ukumbozwa okubanzi (kuze kufike kumamitha ayi-240) naku-isibambo isivinini kufika ku-50 Mbit / s.
