Bluetooth

Ezweni elihlala livela futhi elithuthukayo lobuchwepheshe obungenawaya, kunesidlali esisodwa esibalulekile esibe sibalulekile endleleni amadivaysi axhumana ngayo wodwa: i BluetoothLobu buchwepheshe, osebuphenduke ithuluzi elibalulekile ezigidini zabantu emhlabeni jikelele, buvumela ukudluliswa kwedatha nolwazi. phakathi kwamadivayisi ngaphandle kwesidingo sezintambo.

I-Bluetooth ubuchwepheshe bokuxhumana obungenantambo eyayiklanyelwe ngokuyinhloko ukuqeda izintambo phakathi kwamadivayisi, kodwa iye yavela ukuze inikeze amathuba amaningi kanye nezinhlelo zokusebenza eziningi. Ezingeni eliyisisekelo, ivumela ukuxhumana okusheshayo nokulula phakathi kwezinto ezimbili zikagesi, okwenza kube lula kakhulu kuyo yonke into kusukela ekulaleleni umculo kuya kokwabelana ngamafayela.

Umlando kanye Evolution of Bluetooth

I-wireless standard Bluetooth, eyakhiwa ngo-1994 ngu-Ericsson, yaklanywa ukuthi ithathe indawo yezintambo phakathi kwamadivaysi nezinye izisekeli. Ubuchwepheshe buqanjwe ngenkosi yaseDenmark. I-Harald Bluetooth, eyahlanganisa izizwe eziningana zaseDenmark zaba isizwe esisodwa. Leli gama liphakamisa isifiso sobuchwepheshe sokuhlanganisa amadivayisi avela kubakhiqizi abahlukene, njengamakhompyutha nomakhalekhukhwini. Njengephrothokholi yezokuxhumana, iye yavela ngokokubili isivinini nobubanzi.

Inguqulo yokuqala ye-Bluetooth, 1.0, yakhululwa ngo-1999 inamandla alinganiselwe. Kusukela lapho, kuye kwenziwa ukubuyekezwa okuningi kobuchwepheshe ukuze kuthuthukiswe ukusebenza kwawo kanye nokusebenza kahle kwamandla. I-Bluetooth 5.0, eyethulwe ngo-2016, imele ukugxuma okukhulu phambili, enikeza isivinini esiphindwe kane esisheshayo sokudlulisa idatha kanye nobubanzi obuphindwe kabili kokwandulele.

• I-Bluetooth 1.0: Ikhishwe ngo-1999, inobubanzi obungamamitha ayi-10.
• I-Bluetooth 2.0: Ikhishwe ngo-2004, yayinesivinini sokudlulisa esifika ku-3 Mbit/s.
• I-Bluetooth 3.0: Ikhishwe ngo-2009, yethula imodi enesivinini esikhulu, evumela ukudluliswa kwedatha kufika ku-24 Mbit/s.
• I-Bluetooth 4.0: Ikhishwe ngo-2010, yethula i-Bluetooth Low Energy, intuthuko enkulu kumadivayisi asebenza ngebhethri.
• I-Bluetooth 5.0: Ikhishwe ngo-2016, inejubane lokudlulisa elifika ku-50 Mbit/s kanye nobubanzi obufika kumamitha angu-240 ngaphansi kwezimo ezifanele.

⁢Nakuba sisekhona isikhala sokuthuthukisa, i ukuthuthukiswa kwe-Bluetooth iye yaba yinhle futhi iyaqhubeka nokwandisa amandla ayo ukuze ihlangabezane nezidingo eziguqukayo zokuxhumana okungenantambo.

Izici Zobuchwepheshe ze-Bluetooth Technology

La ubuchwepheshe be-bluetooth Ibonakala kakhulu ngokuba wuhlelo lokuxhumana olungenazintambo oluvumela ukudluliswa kwedatha nezwi ezindaweni ezikude, kusetshenziswa amaza omsakazo webanga elifushane. Inhloso yayo enkulu ukuqeda izintambo ezixhumanisa izinto zikagesi nezokuxhumana, kusetshenziswa ukubhanqa kwangaphambili kwemishini ezoxhunywa. Ezinye izici zobuchwepheshe ezifanele kakhulu zingashiwo, njenge:

• Ivumela ukuxhumana endaweni engaba amamitha ayi-10 (i-Bluetooth Class 2), enwebeka kuze kufike kumamitha ayi-100 (i-Bluetooth Class 1).
• Isebenzisa i-2,4 GHz frequency spectrum, efanayo nobunye ubuchwepheshe obungenawaya.
• Inikeza ithuba lokwenza ukuxhumana ngesikhathi esisodwa amadivaysi ambalwa (kufika ku-7).

Mayelana ukuphephaI-Bluetooth isebenzisa umthetho olandelwayo wokuqinisekisa kanye nokubethela kokhiye oyimfihlo ukuvikela ukudluliswa kwedatha. Ubuchwepheshe be-Bluetooth buyaqhubeka nokuvela, ngezinguqulo ezintsha ezithuthukisa izici ezifana nobubanzi nesivinini sokudlulisela. Lezi zinguqulo zifaka:

• I-Bluetooth 2.0: Le nguqulo yethulwe ngo-2004, yandisa isivinini sokudlulisela ku-3 Mbits/s.
• I-Bluetooth 3.0 + HS: Yethulwa ngo-2009, yafinyelela isivinini esingu-24 Mbits/s isebenzisa i-WiFi yokudlulisa idatha.
• I-Bluetooth 4.0: Kusukela ngo-2010, ubuchwepheshe be-BLE (Bluetooth Low Energy) bafakwa ukuthuthukisa ukusebenza kahle kwamandla.
• I-Bluetooth 5.0: Inguqulo yakamuva, ekhishwe ngo-2016, inikeza isivinini esiphindwe kabili kanye nobubanzi obuphindwe kane uma kuqhathaniswa nenguqulo 4.2.

Ukusetshenziswa kwamanje kanye nezicelo ze-Bluetooth

I-Bluetooth ⁤iyisisekelo ⁢ku ukuphila kwansuku zonke namuhla, ukwenza kube lula futhi kuvumele ukushintshana kolwazi phakathi kwamadivayisi. Isicelo sayo ku izinhlelo ze-hands-free ezimotweni, ukukwazi ukulawula ifoni ngaphandle kokuthi uyithinte, kuqinisekisa ukuphepha ngenkathi ushayela. impilo, isetshenziselwa ukuxhuma izinto zezokwelapha, njengeziqapha ukushaya kwenhliziyo noma ama-glucometer, ngokuqondile kumishini yomuntu siqu ehlakaniphile, iqinisekisa ukuqapha okunembe kakhudlwana nokusheshayo kwempilo yesiguli. Esifanekisweni ukusakaza komsindo, ivumela ukuxhumeka kuzipikha, ama-headphone, namasistimu omsindo movie ekhaya, esikhulula ezintanjeni.

Ngakolunye uhlangothi, ukubaluleka kwayo embonini akunciphi ngokuhamba kwesikhathi. Kuyinto evamile e ukuphathwa kwempahla, njengoba abafundi bebhakhodi namanye amathuluzi okulandelela esebenzisa ubuchwepheshe. Ngokufanayo, ku ukulawula ukukhiqiza, njengoba amanye amadivayisi okufunda nokulawula azuza ekuxhumekeni okungenantambo, okuthuthukisa ukusebenza kahle. Iphinde ibe neqhaza ku izinzwa zezimboni, ukuqoqa idatha ngesikhathi sangempela kanye ⁢nokuqapha nokulawula emikhakheni eyahlukene yezimboni. Ngaphandle kokungabaza, i- I-Intanethi Yezinto (IoT) kube yimbangela yokusetshenziswa kwe-Bluetooth, evumela noma iyiphi idivayisi ukuthi ixhunywe nayo idivayisi yethu mobile noma phakathi kwabo. Ekugcineni, singabala i ukulandelela nokulandelela wezinto ezilahlekile, ngokusebenzisa omaka abahlakaniphile abazivumela ukuthi zitholakale ngesignali ye-Bluetooth.

Izincomo Zokusetshenziswa Okulungiselelwe Kwe-Bluetooth

Ukuze uthole okuningi kubuchwepheshe be-Bluetooth, kubalulekile ukucabangela imihlahlandlela ethile. Okokuqala, qiniseka ukuthi womabili amadivayisi ane-Bluetooth evuliwe futhi akumodi etholakalayo.. Ukuze wenze lokhu, ngokuvamile udinga ukuya kuzilungiselelo zedivayisi yakho bese ubheka inketho ye-Bluetooth. Kwamanye amadivaysi, kungase kudingeke ukuthi ufake “imodi yokumatanisa” ukuze uvumele amanye amadivaysi ukuthi ayithole. Uma zombili izisetshenziswa sezibonakala komunye nomunye, kufanele zikwazi ukuxhuma.

Okwesibili, gcina amadivayisi akho e-Bluetooth asesikhathini samanje.. Njengoba nje izibuyekezo zesofthiwe zingathuthukisa ukusebenza nokuvikeleka kwekhompyutha yakho noma iselula, izibuyekezo ze-firmware (isofthiwe elawula izingxenyekazi zekhompuyutha zedivayisi yakho) zingenza okufanayo kumadivayisi akho e-Bluetooth. Qiniseka ukuthi uhlola njalo izibuyekezo ezitholakalayo zamadivayisi akho.

• Khulisa isignali yakho ye-Bluetooth. Ibanga phakathi kwamadivayisi e-Bluetooth lingaphazamisa ukusebenza kwawo. Ukuze uthole isignali engcono kakhulu, zama ukugcina idivayisi yakho isondelene kakhulu ngangokunokwenzeka, okungcono iqhelelene ngamamitha ambalwa. Uma lokhu kungenzeki, zama ukunciphisa inani lezithiyo ezibonakalayo phakathi kwazo.
• Xhuma amadivaysi ahambisanayo. Akuwona wonke amadivayisi e-Bluetooth asebenzisana kahle. Ngaphambi kokuthenga idivayisi ye-Bluetooth entsha, yenza ucwaningo lwakho ukuze uqiniseke ukuthi iyasebenzisana namadivayisi osuvele unawo. Izikhathi eziningi, abakhiqizi bedivayisi bahlinzeka ngohlu lwamadivayisi ahambisanayo kubo amawebhusayithi.
• Yehlisa ukusetshenziswa kwebhethri. Ukusebenzisa i-Bluetooth kungadla amandla amaningi. Uma ubona ibhethri ledivayisi yakho liphela ngokushesha ngenkathi usebenzisa i-Bluetooth, zama ukunciphisa ukusetshenziswa kwayo noma ukulivala uma lingasebenzi.
