Zisho ukuthini izimpawu ze-3G, H, H +, 4G, G, no-E ku-smartphone yami?

Uma une-smartphone futhi uyisebenzisela ukushaya izingcingo noma ukuxhuma ku-inthanethi, kuqinisekile ukuthi isithonjana sizovela kubha yezaziso ekhombisa izinga lokufakwa. Eduze kwalokhu kunencwadi. Lezi zinhlamvu zingaba yisithupha, kuye ngezici zeselula: 4G, H +, H, 3G, E kanye no-G. Isho ukuthini ngayinye yalezi zinhlamvu?

Kungenzeka ukuthi usubonile ukuthi ngezinhlamvu ezithile ukuxhumana kwe-inthanethi kuhamba kancane. Empeleni, lezo zinhlamvu zibonisa kuphela uhlobo lokuxhumana kweselula olusetshenziswa iselula. Okunye kwalokhu kuxhumana kweselula kusezingeni eliphezulu, kanti okunye akunjalo. Ezinye zivumela ukudluliswa kwedatha okusheshayo, kanti ezinye zisebenzisa amandla ebhethri amancane. Iluphi uhlobo lwenethiwekhi oluhambisana nohlamvu ngalunye lwalezi?

1.- G ye-GPRS: Siqala ngalolo oluvela kuwo wonke ama-smartphone. Ayikho i-smartphone eyodwa engasekeli amanethiwekhi e-GPRS. Isifinyezo salo sivela ku-General Packet Radio Service, noma isevisi yomsakazo wephakethe jikelele. Kuyisandiso, ngakho-ke kuhlanganisa, isistimu yezokuxhumana yeselula yomhlaba wonke, okuyiyona nto esivame ukuyisebenzisela ukushaya izingcingo. Le nethiwekhi isakazeke kakhulu kulo lonke elaseSpain. Uma silahlekelwa ukufakwa kwesivinini esikhulu, cishe sisazoba nayo i-GPRS. Ivumela isivinini sokudlulisa esingu-56 kuya ku-144 kbps. Inethiwekhi enensayo kakhulu, futhi cishe ayikulungele ukusefa i-inthanethi. Izohamba kancane ukuthumela nokwamukela imilayezo ku-WhatsApp, isibonelo, nakuba sibekezele, kuzosebenza. Ingcono kakhulu ekwenzeni izingcingo, ngoba isabalele kakhulu, futhi cishe sizohlala sinokuxhumana. Uma sisekhaya, futhi singalokothi sibe nekhava, ukukhetha kuphela amanethiwekhi e-2G njenge-GPRS kungaba yisixazululo.

2.- E ye-EDGE: Isifinyezo saso sivela kuzilinganiso Zedatha Ethuthukisiwe ze-GSM of Evolution, okusho ngesi-Spanish ukuthi Izilinganiso Zedatha Ezithuthukisiwe Ze-GSM Evolution. Ngokombono, lokhu kuxhumana sekuvele kubhekwa njenge-3G, kodwa iqiniso liwukuthi isivinini salo esiphezulu singama-348 kbps, okusabonakala kuncane. Sizoba nezinkinga zokuphequlula i-inthanethi, ukubuka ividiyo noma ukulanda ifayela elikhulu kuyinto engacabangeki, kodwa empeleni singakhuluma ku-WhatsApp kalula kakhulu, kanye nokuthumela ama-imeyili afaka umbhalo kuphela. Iwuhlamvu oluvame ukuvela lapho sikholelwa ukuthi i-inthanethi ayisheshi ngenxa yokuthi asinakho ukufakwa. Empeleni asinakho ukufakwa kwenethiwekhi enesivinini esikhulu, kodwa sinayo i-EDGE.

3.- 3G noma UMTS: Isifinyezo salo sivela ku-Universal Mobile Telecommunications System, nakuba ngokuvamile sibhekisela kuyo kakhulu njenge-3G. Kodwa-ke, kwamanye ama-smartphones, esikhundleni se-3G, kuvela uhlamvu u-U, futhi lwe-UMTS, nakuba lufana. Kubhekwa njengesizukulwane sesithathu sesistimu yeselula. Kuyindinganiso edalelwe ukudlulisa izwi nedatha, ngakho-ke singakwazi ukushaya izingcingo ngalawa manethiwekhi, kanye nesiphequluli se-inthanethi. Ijubane layo lifinyelela ku-2 Mbps. Inkinga enkulu ukuthi le nethiwekhi ayisabalele njengoba injalo ngenethiwekhi ye-GPRS, okusho ukuthi ukuthembela kuphela ku-3G ukuze ushaye ucingo kungase kungabi okungcono kakhulu.

4.- HSDPA H: Isifinyezo saso sivela ku-High Speed ​​​​Downlink Packet Access. Isekelwe ku-UMTS, kodwa iqiniso liwukuthi ihlanganisa isiteshi esisha esabiwe ku-downlink, evumela isivinini sokulanda esingu-14 Mbps. Ngalesi sivinini singabuka amavidiyo ngaphandle kwenkinga. Kanye nokulanda amafayela amakhulu, noma izinhlelo zokusebenza, ngaphandle kwesidingo sokuxhunywa kunethiwekhi ye-WiFi enesivinini esikhulu.

5.- H + kusuka ku-HSUPA noma i-HSPA: Isifinyezo saso sivela ku-High Speed ​​​​Uplink Packet Access. Eqinisweni, kuwuhlelo olufana nolwedlule, nakuba kungekona nje kuphela isivinini sokulanda esithuthukisiwe, kodwa futhi nesivinini sokulayisha ekudlulisweni, ukuze isivinini se-22 Mbps sokulayisha kanye nokulandwa kwe-84 Mbps singafinyelelwa. Umehluko ngesistimu yangaphambilini ukuthi ngokuba nesivinini esiphezulu sokulayisha, asikwazi ukulanda ividiyo kuphela, kodwa futhi siyithumele, ukuze kusungulwe isisekelo sokwenza amakholi we-IP, noma ngisho namakholi wevidiyo aphezulu.

6.- I-4G noma i-LTE: Isizukulwane sesine soxhumo lweselula. Ukufakwa kwayo eSpain akusakazeki kakhulu, nakuba opharetha bephikelela ngokuthi yebo. Izivinini zokuxhuma ezithiyori zingasivumela ukuthi sifinyelele ku-50 Mbps phezulu nomfula, kanye ne-100 Mbps ezansi nomfula, isivinini abaningi bethu abangenaso ngisho ekuxhumekeni okugxilile ekhaya.
