I-Bluetooth noma i-Wi-Fi emotweni yakho?
I-Bluetooth ne- Wi-Fi kukhona ubuchwepheshe obufanayo ezingeni eliyisisekelo lomqondo, kodwa banezicelo zangempela zezwe zangempela emotweni noma iloli lakho. Indlela eyinhloko oyisebenzisa ngayo i-Bluetooth emotweni ukuxhuma ifoni yakho kwi-stereo yakho, kuyilapho i-Wi-Fi isetshenziselwa ukwabelana uxhumano lwe-inthanethi kusuka efonini noma ku-hotspot kwamanye amadivayisi afana neyunithi yakho yekhanda noma ithebhulethi. Kukhona inani elithile lokuqoqa, okungaholela ekudidekeni okuthile mayelana nokuhlukana phakathi kwe-Bluetooth ne-Wi-Fi, kodwa ubuchwepheshe empeleni buhlukile kakhulu uma ubheka ngokushelela.
Okuyisisekelo se-Bluetooth
I-Bluetooth iyi-protocol yenethiwekhi engenazintambo eyakhiwe ekuqaleni ukuthatha indawo yamakhodi asekudala enethiwekhi. Isebenza ngokuvumela amadivaysi amabili ukuba axhumane ngomakhalekhukhwini ngaphandle kokudluliselwa komvamisa womsakazo. Eqinisweni, isebenza ebangeni elifanayo le-2.4 GHz elisetshenziselwa amakhemikhali amaningi angenayo i-Bluetooth njengamagundane namakhibhodi, amanye amafoni angenantambo, namanethiwekhi athile we-Wi-Fi.
Ububanzi bexhumano lwe-Bluetooth lunikezwa cishe ngamamitha angaba ngu-30, kodwa ibanga lincane kakhulu ezimweni eziningi ezisebenzayo. Ngenxa yalolu hlu olufushane, amandla aphansi we-Bluetooth, nezinye izici, uxhumano lwe-Bluetooth luthiwa ukudala inethiwekhi yendawo yomuntu siqu (i-PAN). Lokhu kungaqhathaniswa nohlobo lwenethiwekhi yendawo yendawo (LAN) ongayidala nge-Wi-Fi.
I-Wi-Fi ayiyona inthanethi
Enye yezingqondo ezingalungile mayelana ne-Wi-Fi yukuthi inokuthile okuphathelene ne-intanethi. Kuyiphutha elilula ukwenza, ngoba ukusabalala okubanzi kwe-Wi-Fi kusho ukuthi abantu abaningi baxhuma kwi-intanethi ngokuxhumeka kwinethiwekhi ye-Wi-Fi . Noma kunjalo, yonke inethiwekhi ye-Wi-Fi ixhuma amakhompiyutha noma ama-computer amaningi noma amadivaysi ku-router central kanye nomunye nomunye. Uma leyo router ixhunyiwe kwi-intanethi, amanye amadivaysi enethiwekhi angabuye afinyelele ku-intanethi.
Ngenkathi i-Bluetooth isetshenziswa ngokuyinhloko ukuxhuma amadivayisi amabili komunye nomunye kunethiwekhi yendawo yomuntu siqu, i-Wi-Fi isetshenziswa kakhulu ukuxhuma amadivaysi owodwa noma ngaphezulu ku-router. I-router ivumela amadivaysi ukwabelana ngolwazi emuva nangaphezulu njenge-LAN enezintambo. Ama-routers amaningi namuhla akhiwe ngamamodemu, kodwa empeleni amadivaysi ahlukene. Eqinisweni, kungenzeka ukusebenzisa router engenantambo ukudala inethiwekhi ye-Wi-Fi ngaphandle kokuxhumeka kwe-Inthanethi okuhilelekile. Kulolu hlobo lwesimo, amadivaysi ngabanye angabelana ngemininingwane komunye nomunye, kodwa akakwazi ukufinyelela ku-intanethi.
Kunezimo lapho idivayisi eyodwa noma ngaphezulu ingaxhunyiwe nge-Wi-Fi ngaphandle komzila, kodwa ziyinkimbinkimbi kakhulu ukusetha. Lolu hlobo lokuxhumeka lubizwa ngokuthi inethiwekhi ye-ad hoc, futhi ngokuyisisekelo ivumela idivaysi evunyelwe i-Wi-Fi ukuxhuma kumadivaysi owodwa noma ngaphezulu ngaphandle komzila. Uma ngabe idivaysi, kungakhathaliseki ukuthi ifoni, i-laptop, noma okunye, inokuxhumeka kwe-intanethi, ngakho-ke kungenzeka ngezinye izikhathi ukwabelana ngaloxhumano.
I-Wi-Fi isebenza ngemvamisa yomsakazo njenge-Bluetooth, kodwa ububanzi benethiwekhi ye-Wi-Fi ngokuvamile buyobe bukhulu kakhulu kunombono wokuxhumana kwe-Bluetooth. Nakuba amanethiwekhi amaningi we-Wi-Fi asebenzisa ibanga elifanayo le-2.4 GHz njenge-Bluetooth, i-Wi-Fi isebenzisa amandla amaningi. Eqinisweni, ezinye izivivinyo zibonise ukuthi iBluetooth isebenzisa kuphela amaphesenti amathathu wamandla njenge-Wi-Fi ukwenza imisebenzi efanayo.
Umehluko Phakathi kwe-Bluetooth ne-Wi-Fi
Ngaphandle kokubanzi nokusetshenziswa kwamandla, i-Wi-Fi ne-Bluetooth ibuye ihluke ngokuhambisana nesivinini sokudlulisa idatha. I-Bluetooth ivame ukuhamba kancane, futhi inikeza umkhawulokudonsa ongaphansi, kune-Wi-Fi. Lesi esinye sezizathu zokuthi ikhwalithi ye-Bluetooth yomsindo ayikho enkulu, kuyilapho i-Wi-Fi ingasetshenziselwa ukusakaza umculo ophezulu wekhwalithi, okuqukethwe kwevidiyo, nedatha.
Isibonelo, i-Bluetooth 4.0 inikeza isivinini esikhulu kunezinguqulo zangaphambili zobuchwepheshe. Noma kunjalo, i-Bluetooth 4.0 isabanjwe ku-25Mbps. Ukuvinjelwa kwenethiwekhi ye-Wi-Fi kuncike kuye ngokulandelana komthetho othile, kepha ngisho ne-Wi-Fi Direct esheshayo, engumncintiswano we-Bluetooth, ingahlinzeka ngesivinini esingama-250 Mbps.
Nakuba i-Bluetooth ne-Wi-Fi bobabili basetshenziselwa ukwakha amanethiwekhi angenantambo angenawo ama-wireless, kunezimpikiswano ezinkulu nokuthi ubuchwepheshe obunye buvame ukusetshenziswa kanjani. Njengoba i-Bluetooth iklanyelwe ukuxhuma amadivaysi amabili komunye nomunye ebangeni elifushane, amandla aphansi, inethiwekhi yendawo yomuntu siqu, ihambelana kahle nemibono eminingi yokusetshenziswa emotweni noma iloli lakho.
Indlela eyinhloko yokusebenzisa i-Bluetooth emotweni yakho ukusiza ukushaya ucingo lwezandla. Lokhu kungathatha ifomu lokuxhuma i-earpiece ye-Bluetooth efonini yakho, noma kungabandakanya ukuhlanganisa ifoni yakho ekhanda eliyinhloko elihambisanayo noma uhlelo lwe-infotainment. Ezimweni ezithile, ukuhlanganisa ifoni yakho ekhanda lakho lekhanda kuzokuvumela ukuba wenze futhi uthole izingcingo nge-system yakho yomsindo, uguqule ngokuzenzakalelayo umsakazo wakho, ngaphandle kokuthi uthinte ifoni yakho noma izilawuli zomsindo we-stereo.
I-Bluetooth nayo inikeza indlela elula kakhulu yokulalela iqoqo lakho lomculo we-digital , noma usakaze umculo kusuka enkonzweni efana no-Pandora noma i-Spotify , kusuka efonini yakho. Lokhu kuhilela ukuhlanganisa ifoni ekhanda eliyinhloko elihambisana ne-Bluetooth , futhi ngokuyisisekelo lisebenza njengekhebula elisizayo elingenantambo. Kwezinye izimo, ungase ukwazi ngisho nokulawula ukudlala ngeyunithi yakho yekhanda ngaphandle kokuthinta ifoni yakho.
Ngokuvamile i-Wi-Fi ayisetshenziselwa lezo zinhlobo zezimo, kodwa lokho akusho ukuthi akusizi emotweni yakho. Indlela eyinhloko ongayisebenzisa ngayo lobu buchwepheshe emotweni yakho ukudala inethiwekhi engenazintambo ukuhlanganyela uxhumano lwe-Intanethi noma uxhuma amadivayisi amaningi komunye nomunye. Uma ifoni yakho inamandla okufaka ama-tethering, noma une- hotspot engenawo ozinikezele , ungasebenzisa lolu hlobo lwenethiwekhi ukuze unikeze uxhumano lwe-inthanethi kwiyunithi yekhanda ehambisanayo, amaphilisi, izidakamizwa zegeyimu eziphathekayo, nokuningi.
Ukuthi i-Wi-Fi Direct iphikisa kanjani isimo
Nakuba i-Bluetooth ngokuvamile ibonakala njengendlela engcono yokuxhuma amadivaysi amabili komunye nomunye, i- Wi-Fi Direct iyinkimbinkimbi isimo . Isizathu esiyinhloko sokuthi i-Wi-Fi ibhekwe njengento engalungile yokuxhuma amadivaysi ngaphandle komzila ukuthi ukuxhumeka okunamandla kwe-Wi-Fi ngokuvamile kunzima ukusetha futhi kuhlushwa yizimbungulu zejubane.
I-Wi-Fi Direct iyithatha entsha ukuthatha idivaysi kuya kudivayisi nge-paradigm ye-Wi-Fi ethatha amakhasi ambalwa kusukela ebhukwini lokudlala le-Bluetooth. Umehluko omkhulu phakathi kwezixhumanisi zedabuko ye-Wi-Fi yesikhombimkhuba kanye ne-Wi-Fi Direct yilokho okulandelayo kufaka ithuluzi lokuthola. Lokhu kusho ukuthi nje, njenge-Bluetooth, i-Wi-Fi ngqo iklanyelwe ukuvumela amadivaysi ukuthi 'athole' ngomyalo ngaphandle kwesidingo somsebenzisi ukubhekana nokuhlupheka kokusetha inethiwekhi ye-ad hoc.
Ingabe i-Wi-Fi izofaka i-Bluetooth emotweni?
Iqiniso liwukuthi i-Wi-Fi iphakeme kuneBluetooth ngezindlela eziningi, kuhlanganise kokubili ububanzi nejubane, futhi ngokuyisisekelo i-Wi-Fi Direct idlula inzuzo eyinhloko ye-Bluetooth yokuba lula. Noma kunjalo, akukho okunye okubaluleke kakhulu esikhathini esifushane. Iqiniso liwukuthi i-Bluetooth isivele iyisici eziningi ze-OEM ne-aftermarket head units, futhi ihlanganisiwe cishe kuwo wonke ama-smartphone wanamuhla.
Nakuba ubuchwepheshe be-smartphone buvame ukuhamba futhi buvumelane kahle ngokushesha, ubuchwepheshe bezimoto ngokuvamile buhle kakhulu ngemuva kwejika. Ngakho-ke noma ngabe i-Wi-Fi Direct ithathe indawo ye-Bluetooth ngokuphelele kwezinye izinhlelo zokusebenza, cishe kuzothatha isikhashana ukuze kubonakale kudatha yemoto yakho entsha.
Olunye udaba nge-Wi-Fi, ne-Wi-Fi Direct, ukusetshenziswa kwamandla, okuzohlala kuyinkinga kumadivayisi eselula. Lokhu akuyona into enkulu emisebenzini yezimoto, lapho okungenani ezinye zezinga lamandla engeziwe atholakala ezimotweni eziningi, kodwa kuyinhlangano enkulu yamafoni, abadlali be-MP3, namanye amadivayisi eselula. Futhi i-Bluetooth ivame ukusetshenziswa kakhulu ezimotweni ukwenza izingcingo ezingenazo izandla futhi usakaze umculo, kokubili okubandakanya ucingo, i-Bluetooth mhlawumbe ayihambanga noma yimuphi isikhathi maduzane.
