Yintoni eyahlukileyo ukusuka 3G 4G noko ukukhetha?

Ubomi bethu ukhawulezisa, kwaye ulwazi zilinganisiwe umoya yonke imihla. Namhlanje, bambalwa abantu yanelisekile, kangangokuba usebenzisa iselula nje ukuhlala ngaphandle kwebala, kwaye ngoku bonke ufuna ukuba zibandakanywe ngokupheleleyo isithuba ulwazi. zezingxoxo, uthungelwano zentlalo, ividiyo - zonke ezi ngamakhubalo zifuna ukuze babe uqhagamshelwano esisigxina kwi Internet. ukukhusela ufikelelo abasisigxina inethiwekhi kulula, nkqu imifuziselo ifowuni ngexabiso kakhulu ukufikelela ngenxa EDGE kunye GPRS. Kwaye ukuba siye sithethe malunga uqhagamshelo-high speed, ngoko yonke into kunzima kakhulu, njengoko kukho ukhetho. Kwaye njalo buhlungu.

imithombo Primary

Eyona ndlela ilula kakhulu eqhelekileyo ukuqinisekisa ngokwakho kwi Internet esiphathwayo mobile zeefoni esezantsi GPRS, EDGE 3G. Okokugqibela ngeke ngokuba umgangatho. Eli ligama elihlanganisayo usithe isethi imigangatho. Ukuba idivayisi inkxaso 3G, 4G, oko linako ukubonelela ukufikelela lomniniyo kwi Internet ngesantya esiphezulu. Ukuba uphawu liya kuba iingxaki, izixhobo kulula ukutshintshela kwenye EDGE ngaphambili umgangatho okanye GPRS. Ngokutsho nababoneleli zakho ezihambayo, inethiwekhi 3G ukuyo. Kodwa xa kusenziwa ujika ukuphuma kamnandi kangaka bonke. Kukho ezininzi iingxaki ezinxulumene izinto ezahlukeneyo, phakathi kwazo nkqu isiqabu, ngezimanga zendalo , kunye elangeni. Ngaphambi kokuba ucinga ngomahluko phakathi 3G evela 4G, kufuneka siyiqonde ezahlukeneyo kujonge izinto.

Ukukwazi

3G-internet ngokwangoku uhlobo ixhaphakileyo, ngoko 99% ezi iiyunithi asebenza kulo mgangatho. Ngaphambili, i-Internet mobile yindlela elula lokusula yamali, kwaye ngoku abaqhubi bakulungele ukunika abathengi zayo ezahlukeneyo izicwangciso lweerhafu.

Ukuba sithethe ngomahluko phakathi 3G evela 4G, yinto ebalulekileyo, Isimanga ngokwaneleyo, kukho isantya. Xa linokuya liba likhulu inani labantu eqhagamshelwe njengejelo, abancinane kuba yayo bandwidth. Ukuba songeza iindawo coverage ingxaki enzima, ukusuka isantya sethiyori kungabalelwa kuphela ngomhla wesithathu. Nangona kunjalo, oku kuyinyaniso kuphela kwiindawo ezixineneyo lwababhalisi - kwiindawo ezinabantu abaninzi needolophu, kwakunye xa uqhuba. Kwezinye iimeko, maxa wambi izinga utsiba ukurekhoda amaxabiso.

ezinye iinketho

Ngaphambi kokuba sithethe ngomahluko phakathi 3G evela 4G, sifanele ingqalelo izindululo lwabasebenzisi zokusebenza kunye standard nge. Ezi nkcukacha obu bugcisa ibandakanya isisombululo eyahlukileyo ngokupheleleyo ingxaki umthwalo itshaneli kunye nenani abasebenzisi. Umgangatho kunye nokufumaneka umqondiso zixhomekeke, njengoko kwezinye iimeko, ezahlukeneyo izinto. Kodwa kunjalo, la manani usebenzisa ubugcisa nge kubhetele kakhulu GSM ukusetyenziswa. Phantsi kweemeko ezifanelekileyo kwesona santya siphezulu yi ukuya ku 3.2 megabits ngomzuzu.

Kubalulekile ukuphawula ukuba 3G imizila, 4G, nge ayikho njengokuba nabo bahlukahlukene usebenzisa GSM. Noko ke, ukuba oyifunayo, uze apha isixhobo 'yakho' kuya kuba lula kuwe ukuba usebenzise onokuzifumana.

inethiwekhi lte

Phambi kokuba usixelele ngoko yahlukile kwi 3G 4G, kufuneka athi malunga neenethiwekhi lte, ezaqaliswa kutshanje ngabaqhubi eziliqela eRashiya. Kwihlabathi, lo mgangatho sele zisebenza kangangeminyaka. Ingxaki usebenzisa ezi uthungelwano eRashiya usendleleni yokuba zonke iiyunithi amazwe asebenza kuluhlu omoya eyahlukileyo ngokupheleleyo. Kodwa abaqhubi Russian banikele abaxhasi bazo kwi ukukhetha izixhobo elifanelekileyo umsebenzisi kothungelwano enjalo, kwakunye nesicwangciso ngokupheleleyo lweerhafu kunye ephambili. Abasebenzisi uyakwazi ukukhetha ezahlukeneyo lwezixhobo ze zakhiwo, kubandakanywa i-USB-imodem kunye Wi-Fi-imizila nge eyakhelwe-ngaphakathi ibhetri egcwalisekayo ukuba ibe ifakwe kwingxowa kwaye ungakhathazeki ukuba uhambo luza kuba iingxaki ukufikelela kwi-Internet. Kukho imizila esemgangathweni ezinokuthi kuqhagamshelwa umbane umzi kwaye usebenzise ekhaya.

4G kwenethiwekhi

Ngoko ke umahluko phakathi 3G evela 4G? Kubalulekile ukuphawula ukuba neminatha yomibini abe kwimimandla coverage echazwe kakuhle. Kwimeko yesibini, ingxaki ukwanda eliphantsi kwinethiwekhi, kwiimeko ezininzi, sebenzisa 4G kuphela kwizixeko ezikhulu. EMoscow kwaye ndawo eMoscow iya kukugubungela iyachithwa. Eyokuqala bakwazi ukuphuhlisa uhlobo olutsha lwe zokwaleka, imakethi waya "megaphone". Kwaye ngoku sele kwendawo likhulu yonke indawo Russian. Kubalulekile ukuqonda ukuba 3G / 4G utshintshe nje kwenzeka ngokuthe ngcembe, yaye ngoko ke kwendawo liya kukhula kunye nexesha. Le site operator mobile nganye usoloko ingcaciso efanelekileyo malunga kwendawo.

Le nkampani "MTS 'eMoscow kunye nommandla eMoscow iye yafumana indawo esiphelweni yesibini, leyo kwaba yimpumelelo ngenxa kuphuhliso esebenzayo ye-network. Le ndawo zisezantsi umqhubi "Beeline", njengoko inxaxheba kwi "ngokobuhlanga" emva bonke.

inani

Ngoko ke, ngokungafaniyo 3G ukususela 4G yeyona ndlela ukuze kuphunyezwe izinto, kodwa ke ixabiso - le yenye into ebalulekileyo kwimeko zombini yothungelwano. Isantya 4G ayiphelelanga yi umqhubi mobile, kwaye kuxhomekeke kwindlela balayishe network ngalo mzuzu. Umsebenzisi nezi- nasiphi na isicwangciso uluhlu, lo gama ixabiso layo iya kuxhomekeka bandwidth ekhoyo.

izixhobo

Wireless 3G okanye 4G-Internet isebenza eyenye intanethi igxunyekwe. Oku kuyinyaniso ngakumbi apho ababoneleli-nkonzo igxunyekwe ayifumaneki. Umzekelo, ukuba uhlala encinane okanye indlu kwisakhiwo esitsha, kufuneka ukufikelela elungileyo ngesantya esiphezulu-intanethi awukwazi buhlungu. Kulo meko, lo kungcono ukuba usebenzise 3G okanye 4G-umzila. Iza kuba luncedo hayi kuphela lombutho lonikezelo lwe Internet engenazingcingo Wi-Fi, kodwa ukuze afumane ufikelelo esitalini kwi Internet, apho uphawu reception akunakuqinisekiswa. Ukuze wenze oku, sebenzisa i-eriyali lwangaphandle okanye eriyali umsindo.

Yintoni 3G?

3G - iteknoloji engenazingcingo ineendlela ezininzi xa ethelekiswa kwizizukulwana ngaphambili. Eminye imibandela ukwenza umahluko, ingakumbi, ukudluliselwa-high speed, izakhono zaphambili multimedia, kwakunye ukuzulazula jikelele. Le iteknoloji isetyenziswa ukudibanisa mobile phones kwi Internet okanye ezinye iinethiwekhi IP-based abathengi bafumana ithuba lokuba bavakalise okanye unxibelelwano ividiyo, kwakunye nokusetyenziswa kwe-intanethi kunye iifayili zikotshwe.

Yintoni 4G?

Ukuba sithethe 3G Ngokungafaniyo 4G, ngoko, enyanisweni, isibaluli kukuba yokugqibela isebenzisa uluhlu standard omoya entsha, ngoko akukho umva technology ehambelanayo. 4G ijolise ekunikezeleni ukhuseleko olubanzi bonke IP-based (IP-zeefoni, iinkonzo imidlalo, ukufikelela broadband Internet, kunye nesiqulatho multimedia ustrimisho).

4G kanye 3G

Ukuze siqonde ngcono umahluko phakathi kwezi bugcisa ezimbini kuyimfuneko ukuba siqwalasele iingongoma ezithile.

Ingongoma yokuqala yokuthelekisa yi isantya. Akunakuze uyibize ngokuthi umgamgatho, kokona kulungileyo. Kwimeko yokuqala, njengoko kuchaziwe ngaphambili, izinga ixhomekeke ngqo kwi inethiwekhi. 4G isebenza amaxesha 10 ngokukhawuleza kuthelekiswa 3G. Konke kuxhomekeke izixhobo ezisetyenziselwa yokukhulisa iimpawu kunye data.

Ukufika 3G amandla abasebenzisi ukwenza iminxeba ilizwi nodluliselo data ngesantya esiphezulu. Kwimeko zinyuke nge 4G isantya ukudluliselwa kakhulu, ukongeza koku, abathengi babe nako ukusebenzisa umxholo multimedia evela kwi Internet ngqo badlale imidlalo intanethi. Biza imisebenzi kunye data kule yaye kwelinye icala, umsebenzi ngexesha elifanayo.

ukudluliswa kobuchwepheshe

3G isebenzisa amajelo data usuke of ezalathelwe womnatha, kunye neephakheji. kuphela usuke packet esetyenziswa 4G. Ukuba uthelekisa olukhupha bobabini iinethiwekhi, aniyi uzive mahluko. I 4G yonke iminxeba sebenzisa IP-zeefoni, esingekoyo kwi 3G.

Zombini yenethiwekhi rate ugqithiselo lweengcombolo imalunga efanayo, yaye kwinqanaba 5-20 Mbit / s.

isiphelo

Kakade ke, 4G imele iteknoloji phambili ngakumbi, kodwa nokuphunyezwa kwayo ngokupheleleyo sele akukagqitywa, ngoko abasebenzisi akakwazi kunandipha iingenelo. Ekubeni inkxaso 3G, 4G ayikenziwa ziphuhliswe ngokwaneleyo ukuze ugqithele ukuya kwinqanaba elilandelayo, zonke iinkonzo ekufuneka ifumaneke kubasebenzisi, babe yinto lukwisigaba sokuqala sokuphumeza. uthungelwano isizukulwana zakutshanje ezineefitsha nangakumbi na uphando ngokupheleleyo, kunye nezixhobo mihla suku ngalunye ubanzima ngakumbi, ukuze zonke iingenelo ubuchwepheshe uya kuba zibonakala kuphela emva komzuzwana, uze emva koko thelekisa 3G and 4G-Internet ngokupheleleyo.
