Isingeniso ku-1G, 2G, 3G, 4G & 5G Inqwelomoya
Umphathiswa ongenazintambo unokuxhasa i- 4G okanye i-3G ngelixa ezinye iifowuni zakhiwa enye yezo. Indawo yakho inokuvumela iifowuni yakho ukuba ifikelele kwi-2G ngesivinini, okanye ungabona i-5G yegama elijikiweyo xa lithetha nge-smartphone.
Ukususela kwi-1G yaqaliswa ekuqaleni kwee-1980, iteknoloji entsha yokunxibelelana kwee-wireless ikhutshwe phantse kwiminyaka eyi-10. Bonke babhekisela kwi-teknoloji esetyenziswe ngumphathiswa weselula kunye nesixhobo ngokwawo; zineemilinganiselo ezahlukeneyo kunye nempawu eziphucula kwisizukulwana ngaphambi kwayo.
Nangona i-acronym ngamanye amaxesha i-techno ibonisa ukuba umntu ongekho mfuneko akayi kuqonda, abanye kubalulekile ukuqonda kwansuku zonke. Unokufuna ukwazi indlela ezobuchwephesha ezahlukileyo ngayo kwaye zisebenza njani kuwe xa uthengisa ifowuni, ukufumana iinkcukacha zenkcazo, okanye ukubhalisela umphathiswa weselula.
1G: Izwi kuphela
Khumbula i-analog "iifowuni zefowuni" kunye "nefowuni yeendlela", ngendlela ehamba ngayo ngosuku? Iifowuni zaqala nge-1G kuma-1980.
I-1G yi-teknoloji ye-analog kwaye iifowuni ibinobomi bebhetri obubi kunye nekhwalithi yezwi yayininzi ngaphandle kokukhuseleka okukhulu, kwaye ngamanye amaxesha babe namava abaye bawayeka.
Isivinini esikhulu se-1G ngu 2.4 Kbps . Kaninzi "
2G: I-SMS kunye neMMS
Iifowuni zafumana ukuphuculwa kokuqala okukhulu xa behamba ukusuka ku-1G ukuya ku-2G. Le ntshukumo yenzeka ngo-1991 kwiinkonzo ze- GSM kuqala, eFinland, kwaye ngokufanelekileyo zithatha iifowuni ze-analog ukuya kwidijithali.
I-2G ye-teknoloji yefowuni yazisa umnxeba kunye nokubhala umbhalo, kunye neenkonzo zedatha njengeSMS, imiyalezo yezithombe kunye neMMS.
Nangona i-2G ithathe indawo engu-1G kwaye iphakanyiswa yizobuchwepheshe ezichazwe ngezantsi, isasetyenziswa kwihlabathi jikelele.
Isivinini esikhulu se-2G kunye ne-General Packet Radio Service (GPRS) ngu-50 Kbps okanye i-1 Mbps ngeeNtlawulo zeNgcaciso zeDatha ye-GSM Evolution (EDGE). Kaninzi "
2.5G no-2.75G: Ekugqibeleni iDatha, kodwa iNcinci
Ngaphambi kokwenza ukugqithisa okukhulu ukusuka kumanethiwekhi angenazintambo angama-2G ukuya ku-3G, i-2.5G engama-2 ne-2.75G engaphantsi kwayo yayisisigxina sesigxina esasifaka isikhala
2.5G ukuqalisa inkqubo entsha yokupakisha ipakethi eyasebenza ngakumbi kunokuba sisetyenziswe ngaphambili.
Oku kukhokelela kwi-2.75G enika ukunyuka kwamandla okuphindaphinda kathathu. 2.75G nge-EDGE yaqala e-US kunye ne-GSM amanethiwekhi (i-AT & T ibe ngowokuqala). Kaninzi "
3G: Iinkcukacha ezingaphezulu! Ikholi yokufowuna ne-Intanethi ye-Intanethi
Iinqununu ze-3G zaziswa ngo-1998 kwaye zimele isizukulwana esilandelayo kulolu chungechunge; isizukulwana sesithathu.
I-3G iqhutywe ngokukhawuleza kwizantya zokudlulisela idatha ukuze usebenzise iselfowuni yakho kwiindlela ezininzi ezifuna ukufumana idatha njengefowuni yefowuni kunye ne-intanethi yeselula.
Njengesi-2G, i-3G yavela kwi-3.5G kunye no-3.75G njengoko ezinye iinkalo zenziwe ngenjongo yokuzisa i-4G.
Ijubane elikhulu le-3G liqikelelwa libe malunga ne-2 Mbps kwiidivaysi ezingahambiyo kunye ne-384 Kbps ekuhambiseni izithuthi. Ijubane elikhulu kwi-HSPA + liyi-21.6 Mbps. Kaninzi "
4G: I-Standard Standard
Isizukulwana sesine sezonxibelelwano sibizwa ngokuba ngu-4G, esakhishwa ngo-2008. Sixhasa ukufikelela kwi-intanethi njenge-3G kodwa kunye neenkonzo zokudlala, i-HD yeselula ye-HD, i-video conferencing, i-3D TV kunye nezinye izinto ezifuna ukuphakama okuphezulu.
Ngokuphunyezwa kwe-4G, ezinye iimpawu ze-3G zisuswe, njenge-teknoloji yerediyo yerediyo; ezinye zongezwa kumazinga aphezulu aphezulu ngenxa yama-antenna ahlakaniphile.
Isantya esiphezulu senethiwekhi ye-4G xa ifowuni ishukunywe yi-100 Mbps okanye i-1 Gbps zokunxibelelanisa okuphantsi kokuhamba njengokuba kumile okanye ukuhamba. Kaninzi "
5G: Ukuza kungekudala
I-5G iteknoloji engenazintambo ezingenakwenziwa esenzelwe ukuphucula kwi-4G.
I-5G ithembisa ngokukhawuleza amaxabiso eedata, ukuxinisa okuphezulu, ukukhanya kwezantsi, phakathi kwezinye izinto eziphuculweyo. Kaninzi "
