Yintoni GPRS nendlela amalungiselelo oku iteknoloji

Namhlanje, uphuhliso information technology ngalo kwinqanaba lokuba ezifunyaniswe ezahlukeneyo kunye nempembelelo yawo kamva kubomi bethu yenzeka phantse yonke imihla. Nkqu izolo, babengazi ukuba yintoni cell phone, yaye namhlanje Andiqondi nokuba iiyure ezimbalwa ngaphandle lesiphumo nawuphi na umntu namhlanje. Ngoko ke yintoni na ifowuni ngoku ayinayo ukufikelela kwi-intanethi? Ngaba wakha wazibuza ukuba njani na umsebenzi Internet mobile le nto? Eli nqaku liza kukuxelela into GPRS nendlela amalungiselelo obu bugcisa.

Ezingeyomfuneko igama GPRS livela ibinzana IsiNgesi General Packet Radio Service, leyo iguqulelwe njenge inkonzo packet Radio. Enyanisweni, lo bugcisa yakhelwe phezu GSM standard lonxibelelwano mobile, nto leyo evumela ukudlulisela data. Ngamanye amazwi, enkosi oku, ifowuni yakho Ungathumela ufumane iipakethi data evela kwezinye iinethiwekhi. Kodwa yintoni na GPRS ukuba kumsebenzisi wenethiwekhi umsebenzisi avareji? Ukuba impendulo elula, lithuba lokuba ukudibanisa kwi Internet ngqo kwi mobile yakho. Le Velocity ziya kuba encinane, kodwa iindleko zale nkonzo, uya kuba ekholiswa.

Makhe sibone ukuba yintoni i-GPRS ayikho kwezobugcisa, kodwa ngokwemiqathango ukufikelela kwi-Internet. Okokuqala, ukuba uyakwazi ukudibanisa kuyo nayiphi na indawo apho "ukubamba" yefowuni yakho. Okwesibini, intlawulo ye Internet-GPRS lwenziwa ngendlela yokuba uhlawula kuphela yezithuthi ofunyenweyo kwaye igqithiselwe, kunokuba yokubonelela ngeenkonzo. Ngoko ke, olu hlobo Internet mobile ekunokuthiwa omnye kakhulu efikeleleka ngokwemiqathango coverage kunye nomgaqo-nkqubo amaxabiso onyanisekileyo.

Enye inkalo yokufikelela enjalo kwi Internet kukuba ububanzi yefrikhwensi (isantya kunye nozinzo umjelo) kuya kuxhomekeka kwiimfuno rhumela - ukuba uqhagamshele kuphela ukukhangela imeyili yabo, isiteshi "ezincinane", yaye xa uthe wagqiba ukuba ulayisha ifayile kokuba uzibaxe izinto, ububanzi yefrikhwensi "eyandisiweyo 'ukuba kunokwenzeka ubuninzi. A isantya esiphezulu of indlela ibango wombane ngokwenkcazo ifikelela 171,2 Kbit / s. Ukuziqhelisa, oku kusenokuba umyalelo yobukhulu ezincinane kwaye kuxhomekeke eziliqela, umzekelo, umgangatho ukusokola ummandla othile nezixhobo yomsebenzisi, ukubonelela le nkonzo. Kwi-avareji, GPRS «ikhaya», izinga hayi ngaphezulu kwe 100.0 kbit / s, buxabise umsebenzisi umyalelo sezingeni zitshiphu ngaphezu kwayo nayiphi na enye ukufikelela kwi-Internet.

Abashishini yenethiwekhi yeselula olu hlobo lwe data, kakhulu, kukho inani yeenzuzo phezu kontanga yayo. Le ngesantya esiphezulu kakhulu, kwaye yababini lula nekhawulezayo, kunye nomthwalo encinane izixhobo kwanaxa rhoqo "Connect" kwi inxalenye umsebenzisi. Ukongeza, umqhubi uyakwazi ukubeka kokuhanjiswa, ngokusekelwe zombini umthamo idatha adluliselwe, kwaye ngumsebenzisi yakho "kumgca" ngelo xesha. Kwakhona ezicacileyo, kunye nenzuzo abathengi le nkonzo - ngendleko ephantsi, kudityaniswe umgangatho kunye nesakhono ukudibanisa esiya nakwiindawo ezisemagqagaleni kuvumela umsebenzisi ukuba nonikezelo olumiyo kuzo email, umxokozelo uze uthumele sihlisa kwaye abe nenxaxheba Internet kwezorhwebo.

Emva kokufumana ulwazi kweli nqaku oko kukuthi GPRS, musa ukulibala ukuba iteknoloji na ukuma ngxi. Kwizixeko ezikhulu, indlela ukudluliselwa kwedata ngokuthe ngcembe indawo ephezulu-speed 3G and Wi-Fi, kwaye kwi "Amaphondo 'ubuninzi rate data usebenzisa uthungelwano zeselula yandiswe ngokubonakalayo imveliso ngokusebenzisa ubugcisa EDGE. Kodwa ke, nangona kunjalo, GPRS kunye namhlanje uhlala indlela uthandwayo zonxibelelwano kwiindawo ezininzi elalisakuba yiSoviet Union.
