Zithetha ntoni iisimboli ze-3G, H, H +, 4G, G, kunye no-E kwi-smartphone yam?

Ukuba une-smartphone kwaye uyisebenzisele ukufowuna okanye ukuqhagamshela kwi-Intanethi, i-icon ngokuqinisekileyo iya kuvela kwibar yesaziso ebonisa inqanaba lokhuselo. Ecaleni kwayo kuvela unobumba. Ezi nobumba zinokuba zintandathu, kuxhomekeke kwiimpawu zeselula: 4G, H+, H, 3G, E kunye noG. Uthetha ntoni ngamnye kwaba nobumba?

Ngokunokwenzeka, sele uqaphele ukuba ngoonobumba abathile unxibelelwano lwe-Intanethi luyacotha. Enyanisweni, ezo nobumba zibonisa kuphela uhlobo loqhagamshelwano lweselula olusetyenziswa yiselula. Ezinye zezo ziqhagamshelo zeselula zikwinqanaba eliphezulu, ngelixa ezinye zingekho. Ezinye zivumela ukudluliselwa kwedatha ngokukhawuleza, kwaye ezinye zisebenzisa ibhetri encinci. Loluphi uhlobo lothungelwano oluhambelana nonobumba ngamnye kwaba?

1.- G ye GPRS: Siqala ngale ivela kuzo zonke ii-smartphones. Akukho nenye i-smartphone engaxhasi inethiwekhi ye-GPRS. Isishunqulelo saso sivela kwiGeneral Packet Radio Service, okanye inkonzo yepakethe yerediyo ngokubanzi. Lulwandiso, kwaye ke lubandakanya, inkqubo yonxibelelwano lweselula yehlabathi, eyona siqhele ukuyisebenzisa ukwenza iminxeba. Le network yeyona isasazeke kulo lonke elaseSpain. Xa siphulukene nokhuseleko lwesantya esiphezulu, kusenokwenzeka ukuba sisenokhuseleko lwe-GPRS. Ivumela isantya sodluliselo ukusuka kuma-56 ukuya kwi-144 kbps. Yinethiwekhi ecothayo kakhulu, kwaye eyona nto inokwenzeka ukuba ayifanelekanga ukukhangela i-Intanethi. Kuza kucotha ukuthumela nokufumana imiyalezo kuWhatsApp, umzekelo, nangona ukuba sinomonde, kuya kusebenza. Yeyona nto ilungileyo yokwenza iminxeba, kuba yeyona ixhaphake kakhulu, kwaye phantse siya kuhlala sinokhuseleko. Ukuba sisekhaya, kwaye asinakuze sibe ne-inshorensi, ukukhetha kuphela iinethiwekhi ze-2G ezifana ne-GPRS ingaba sisisombululo.

2.- E ye-EDGE: Isishunqulelo saso sivela kumazinga eDatha aPhuculweyo ye-GSM ye-Evolution, leyo ngeSpanish ithetha Ukuphuculwa kwamazinga edatha ye-evolution ye-GSM. Kwithiyori, olu xhulumaniso sele lujongwa njenge-3G, kodwa inyaniso kukuba isantya sayo esiphezulu singama-348 kbps, okungabonakali ngathi kuninzi. Siya kuba neengxaki zokukhangela i-Intanethi, ukubukela ividiyo okanye ukukhuphela ifayile enkulu ayinakucingelwa, kodwa ngokomgaqo sinokuthetha kuWhatsApp ngokulula okuphezulu, kunye nokuthumela ii-imeyile ezibandakanya isicatshulwa kuphela. Ngunobumba odla ngokuvela xa sicinga ukuba i-Intanethi iyacotha ngenxa yokuba asinakugubungela. Enyanisweni, asinayo i-intanethi yesantya esiphezulu, kodwa sinayo i-EDGE.

3.- 3G okanye UMTS: I-acronym yayo ivela kwi-Universal Mobile Telecommunications System, nangona sihlala siyibiza ngakumbi njenge-3G. Nangona kunjalo, kwezinye ii-smartphones, endaweni ye-3G, unobumba u-U uvela, kwaye kungenxa ye-UMTS, nangona iyinto enye. Ithathwa njengesizukulwana sesithathu senkqubo yeselula. Ngumgangatho owenziweyo ukuhambisa ilizwi kunye nedatha, ukuze sikwazi ukufowuna ngezi nethiwekhi, kunye nesikhangeli se-Intanethi. Isantya salo sifikelela kwi-Mbps ye-2. Ingxaki enkulu kukuba le nethiwekhi ayixhaphakanga njengenethiwekhi ye-GPRS, oku kuthetha ukuba ukuxhomekeka kuphela kwi-3G ukwenza umnxeba kungabi yinto engcono kakhulu.

4.- HSDPA H: I-acronym yayo ivela kwi-Speed ​​​​Speed ​​​​Downlink Packet Access. Isekelwe kwi-UMTS, kodwa inyaniso kukuba iquka itshaneli entsha ekwabelwana ngayo kwi-downlink, evumela ukuba isantya sokukhuphela i-14 Mbps sifikelelwe.Ngesi santya sinokubukela iividiyo ngaphandle kwengxaki. Kanye nokukhuphela iifayile ezinkulu, okanye usetyenziso, ngaphandle kokuqhagamshelwa kwinethiwekhi ye-WiFi enesantya esiphezulu.

5.- H+ ukusuka HSUPA okanye HSPA: I-acronym yayo ivela kwi-Speed ​​​​Speed ​​​​Uplink Packet Access. Enyanisweni, yinkqubo efana neyangaphambili, nangona kungekuphela nje isantya sokukhuphela esiphuculweyo, kodwa kunye nesantya sokulayisha ekudluliseleni, ukwenzela ukuba i-speeds ye-22 Mbps yokulayisha kunye ne-84 Mbps yokukhuphela inokufumaneka. Umahluko ngenkqubo yangaphambili kukuba ngokuba nesantya esiphezulu sokulayisha, asikwazi ukukhuphela ividiyo kuphela, kodwa siyithumele, ngaloo ndlela siseka isiseko sokwenza iifowuni ze-IP, okanye iifowuni zevidiyo eziphezulu.

6.- 4G okanye LTE: Sisizukulwana sesine soqhagamshelwano lweselula. Ukuphunyezwa kwayo eSpain akuxhaphakanga kakhulu, nangona abaqhubi bagxininisa ukuba ewe. Izantya zoqhagamshelo lwethiyori ziya kusivumela ukuba sifikelele kwi-50 Mbps yokulayisha kunye ne-100 Mbps yokukhuphela, isantya uninzi lwethu olungenalo nakunxibelelwano olusisigxina ekhaya.
