I-Bluetooth okanye i-Wi-Fi kwimoto yakho?
I-Bluetooth ne- Wi-Fi zibuchwepheshe obufanayo kwinqanaba leengcamango ezisisiseko, kodwa zinezicelo zehlabathi zangempela ezahlukeneyo kwimoto okanye iloli. Indlela eyona ndlela oyisebenzisa ngayo i-Bluetooth kwisithuthi kukuxhuma ifowuni yakho kwi-stereo yakho, ngoxa i-Wi-Fi isetyenziswa ngokubanzi ukuxhamla uxhumano lwe-intanethi kwi fowuni yakho okanye kwi-hotspot ukuya kwezinye iifowuni njengeyunithi yintloko okanye ithebhulethi. Kukho inani elithile lokungahlali, okubangakho ukudideka malunga nokuhlukana phakathi kweBluetooth kunye ne-Wi-Fi, kodwa ubuchwepheshe bubukeka buhluke kakhulu xa uthatha ukhangele.
Iisiseko zeBluetooth
I-Bluetooth iyi-protocol yenethiwekhi engena-wire eyayiqulunqwe ekuqaleni ukuba ithathe indawo yamacwecwe endala enethiwekhi. Kusebenza ngokuvumela iifowuni ezimbini ukuba zixhumane ngaphandle kokungena ngefowuni ngee-frequency transmission. Enyanisweni, isebenza kwiphepha elifanayo le-2.4 GHz elisetyenziselwa ezininzi iinkalo ezingenazintambo ze-Bluetooth ezifana namagundane kunye neefowbhodi, ezinye iifowuni ezingenazintambo, kunye neenethiwekhi ze-Wi-Fi.
Uluhlu loxhumo lweBluetooth luyakhiwa ngokubanzi malunga neenyawo ezingama-30, kodwa umgama mfutshane kwiimeko ezininzi ezisebenzayo. Ngenxa yolu hlobo olufutshane, amandla aphantsi aseBluetooth, kunye nezinye izinto, uxhulumaniso lweBluetooth kuthiwa yakha inethiwekhi yommandla wendawo (PAN). Oku kunokungafani nohlobo lwenethiwekhi yendawo yendawo (LAN) ongayidala nge-Wi-Fi.
I-Wi-Fi ayikho intanethi
Enye yeengcamango ezingalunganga malunga ne-Wi-Fi kukuba into enokuyenza nge-intanethi. Iphutha elula ukwenza, ekubeni ukusabalala okukhulu kwe-Wi-Fi kuthetha ukuba abaninzi abantu baxhuma kwi-Intanethi ngokuxhuma kwinethiwekhi ye-Wi-Fi . Nangona kunjalo, inethiwekhi yonxibelelwano ye-Wi-Fi ixhuma enye iikhompyutha okanye iikhompyutha kwi-router ephakathi kunye nomnye. Ukuba loo router ixhunyiwe kwi-Intanethi, ezinye iifowuni kwinethwekhi nazo zingafikelela kwi-intanethi.
Ngoxa iBluetooth isetyenziselwa ukuxhuma iifowuni ezimbini komnye nomnatha kwinethiwekhi yomntu, i-Wi-Fi isetyenziswa ngokuqhelekileyo ukuxhuma enye idivayisi okanye ngaphezulu kwi-router. I-router ivumela amadivaysi ukwabelana ngolwazi emva nangaphandle nje nge-LAN ene-wired. Iimoto ezininzi namhlanje zakhiwa kwiimodem, kodwa ziyizixhobo ezihlukeneyo. Enyanisweni, kunokwenzeka ukusebenzisa i-router engenawucingo ukudala inethiwekhi ye-Wi-Fi ngaphandle kwanxibelelwano lwe-Intanethi. Kwilo hlobo lwesimo, iifowuni nganye zikwabelana ngolwazi kunye nomnye, kodwa abanako ukufikelela kwi-intanethi.
Kukho imeko apho enye okanye ezininzi zixhobo zingaxhunyiwe nge-Wi-Fi ngaphandle komzila, kodwa ziyinkimbinkimbi ukusetha. Olu hlobo lwenxibelelwano lubizwa ngokuba ngumnxeba we-ad hoc, kwaye luvumela i-Wi-Fi ifowuni inikwe amandla ukuxhuma kwelinye okanye ezinye izixhobo ngaphandle kombane. Ukuba ifowuni, ingaba ifowuni, i-laptop, okanye enye indawo, inxibelelwano lwe-intanethi, ngoko ngezinye iimeko kunokwenzeka ukuba ukwabelana ngaloo nxu lumano.
I-Wi-Fi isebenza ngefowuni yomsakazo njengeBluetooth, kodwa uluhlu lweenethiwekhi ze-Wi-Fi luya kuba lukhulu ngokubanzi kunoluhlu lwexhumo lweBluetooth. Nangona amaninzi amanethiwekhi ase-Wi-Fi asebenzisa i-2.4 GHz band njengeBluetooth, i-Wi-Fi isebenzisa amandla amaninzi. Enyanisweni, ezinye iimvavanyo zibonise ukuba iBluetooth isebenzisa kuphela iipesenti ezi-3 zamandla njenge-Wi-Fi ukwenza imisebenzi efanayo.
Ukwahlukana Phakathi kweBluetooth ne-Wi-Fi
Ngaphandle kwebala kunye nokusetyenziswa kwamandla, i-Wi-Fi kunye neBluetooth iyahluke ngokuhambelana nokukhawuleza kweedatha. I-Bluetooth idla ngokukhawuleza, kwaye inika umgama omncinci ongaphantsi, ngaphezu kwe-Wi-Fi. Le yenye yezizathu zokuba umgangatho we-Bluetooth womculo awunjalo, ngelixa i-Wi-Fi ingasetyenziselwa ukuhambisa umculo omgangatho ophezulu, umxholo wevidiyo kunye nolunye ulwazi.
Ngokomzekelo, iBluetooth 4.0 inikela ngesivinini esikhulu kuneenguqulelo zangaphambili zeteknoloji. Nangona kunjalo, i-Bluetooth 4.0 isabhalwa kwi-25Mbps. Isantya seenethiwekhi ze-Wi-Fi ziyahlukahluka ngokuxhomekeke kwiprotokholi ethile, kodwa nangona i-Wi-Fi ngokukhawulezayo, eyi-Bluetooth umncintiswano, inokunika isantya kwi-250 Mbps.
Nangona i-Bluetooth kunye ne-Wi-Fi zombini zisetyenziselwa ukudala amanxibelelwano angancinci angama-wireless, kukho ukungqubana okukhulu kwindlela nganye iteknoloji isetyenziswa ngayo. Ekubeni i-Bluetooth ijoliswe ngokutsha ukudibanisa iifowuni ezimbini omnye nomnye kwibala elifutshane, amandla aphantsi, inethwekhi yommandla wendawo, ufaneleke ngokufanelekileyo kwiimeko ezininzi zokusetyenziswa kwimoto okanye iloli.
Indlela ephambili yokusebenzisa i-Bluetooth kwisithuthi sakho kukuncedisa ukufowunela ukungena ngezandla. Oku kungathatha ifom yokuxhuma i-earpiece ye-Bluetooth kwifowuni yakho, okanye ingaquka ukudibanisa ifowuni yakho kwinqununu yentloko ehambelanayo okanye inkqubo ye-infotainment. Kwezinye iimeko, ukudibanisa ifowuni kwinqununu yakho yekhanda kuya kukuvumela ukuba wenze kwaye ufumane iifowuni nge-sound system, uguqule ngokuzenzekelayo umsakazo wakho, ngaphandle kokuchukumisa ifowuni okanye ulawulo lwevolumu ye-stereo.
I-bluetooth ibonelela ngendlela elula kakhulu yokuphulaphula iqoqo lakho lomculo wedijithali , okanye usakaze umculo kumncedisi onjengePandora okanye uSpotify , ukusuka kwifowuni yakho. Oku kubandakanya ukudibanisa ifowuni kwinqununu yentloko ehambelana neBluetooth , kwaye isebenza njengentambo engabancediyo engenazintambo. Kwezinye iimeko, usenokukwazi ukulawula ukudlala ngeyunithi yakho yentloko ngaphandle kokuchukumisa ifowuni yakho.
I-Wi-Fi ayisoloko isetyenziselwa ezo ntlobo zeemeko, kodwa oko akuthethi ukuba akuncedi kwisithuthi sakho. Indlela ebalulekileyo ongayisebenzisa ngayo lobu bugcisa kwiimoto yakho kukudala inethiwekhi engenazintambo ukwabelana uxhumano lwe-intanethi okanye ukudibanisa amadivaysi amaninzi omnye komnye. Ukuba ifowuni yakho inakho ukulungelelanisa, okanye unayo i -hotspot ezinikezelweyo , ungasebenzisa olu hlobo lwenethiwekhi ukunika uxhumano lwe-intanethi kwiyunithi yentloko ehambelanayo, iipilisi, izixhobo zokudlala imidlalo kunye nokunye.
Indlela i-Wi-Fi ejongene nayo idibanisa imeko
Nangona i-Bluetooth ibonakala njengendlela engcono yokudibanisa iifowuni ezimbini komnye nomnye, i- Wi-Fi Direct idityanisa imeko . Isizathu esona sizathu sokuba i-Wi-Fi ibonwe njengento ephosakeleyo yokuxhuma amadivaysi ngaphandle komzila wokuba uxhulumaniso lwe-Wi-Fi oluxhomekeke kunzima ukusetha kwaye luhlupheke kwizitshixo zokukhawulezisa.
I-Wi-Fi Direct yindlela entsha yokuthatha ifowuni kwisixhobo nge-Wi-Fi paradigm ethatha amaphepha ambalwa kwiincwadi zokudlala zeBluetooth. Ukwahluke kakhulu phakathi kokunxibelelana kwe-Wi-Fi ye-ad hoc kunye ne-Wi-Fi ngqo kukuba okokugqibela kubandakanya isixhobo sokufumanisa. Oko kuthethwa nje ukuba, njengeBluetooth, i-Wi-Fi ngqo yenzelwe ukuvumela amadivaysi ukuba "athole" ngomyalelo ngaphandle kwesidingo sokuba umsebenzisi ahambe ngokukhawuleza ukuseka inethiwekhi ye-ad hoc.
Ngaba i-Wi-Fi iya kufaka iBluetooth kwiiSithuthi?
Inyaniso kukuba i-Wi-Fi iphakamileyo kwiBluetooth ngeendlela ezininzi, kubandakanywa zombini udidi kunye nesivinini, kwaye i-Wi-Fi ngqo ichithisa inzuzo ebalulekileyo yeBluetooth. Nangona kunjalo, akukho nto yinto ebaluleke kakhulu kwixesha elifutshane. Inyaniso kukuba iBluetooth isele ibe yinto eninzi kwi-OEM nakwiiyunithi ze-headmark emva kwee-headmark, kwaye iphinde ifakwe kwi-smartphone nganye yanamhlanje.
Nangona iteknoloji ye-smartphone ithambe ukufuduka kwaye ivumelane ngokukhawuleza, iteknoloji yezimoto ihlala ikude emva kwekhalo. Ngoko nangona i-Wi-Fi Direct ithathe indawo yeBluetooth kwezinye iifayile, mhlawumbi kuthatha ixesha ukuze ibonakaliswe kwidatha yemoto yakho entsha.
Omnye umcimbi nge-Wi-Fi, kunye ne-Wi-Fi ngqo, ukusetyenziswa kwamandla, okuya kuba yinkinga kumadivayisi eselula. Le nto ayiyonto enkulu kwiimfuno zokuhamba ngezimoto, apho ubuncinci ezinye izinga lamandla angaphezulu zifumanekayo kwizithuthi ezininzi, kodwa yintengo enkulu yeefowuni, abadlali be-MP3 kunye namanye amadivayisi eselula. Kwaye i-Bluetooth isetyenziswa kakhulu kwiimoto ukwenza iifowuni ezingenasandla kunye nokusabalalisa umculo, zombini ezo zibandakanya ifowuni, mhlawumbi i-Bluetooth ayiyi ndawo naphina nantoni na.
