Isevisi yeselula ye-4 iyamaxesha angama-10 ngokukhawuleza kunenkonzo ye-3G
I-wireless ye-4G igama elisetyenziswe ukuchaza isizukulwana sesine senkonzo yeselula engenazintambo. I-4G yinyathelo elikhulu ukusuka ku- 3G kwaye ifikelela kwii-10 ngokukhawuleza kuneenkonzo ze-3G. U-Sprint wayengumthubi wokuqala wokubonelela ngesantya se-4G e-US ngokuqala ngo-2009. Ngoku ke bonke abathwali banikela ngenkonzo ye-4G kwiindawo ezininzi zelizwe, nangona ezinye iindawo zasemaphandleni zisenomgca we-3G.
Kutheni i-4G Speed Matters
Njengoko ii-smartphones kunye neepilisi zahlakulela ukukwazi ukusasaza ividiyo kunye nomculo, isidingo sokukhawuleza sabaluleke kakhulu. Ngokomlando, isantya sesantya sasicotha kakhulu kunezo ezibonelelwa ngokuqhagamshelana nokukhawuleza kwebhanki kwiikhompyutha. Isantya se-4G siqhathanisa nokukhetha ezinye iindlela zebroadband kwaye luncedo ngakumbi kwiindawo ezingenakudityaniswa kwebhanti.
4G Technology
Nangona yonke inkonzo ye-4G ibizwa ngokuba ngu-4G okanye i-4G LTE, ubuchwepheshe bobuncinci abufani nabo bonke abathintekayo. Abanye basebenzisa ubuchwepheshe be-WiMax kwintanethi yabo ye-4G, ngelixa i-Verizon Wireless isebenzisa iteknoloji ebizwa ngokuthi i-Long Term Evolution, okanye i-LTE.
I-Sprint ithi i-network yayo ye-4G ye-WiMax inikezela ngesivinini sokukhuphela esishumi ngokukhawuleza kunxibelelwano lwe-3G, ngezantya ezithe zaphuma kwi-megabits ezili-10 ngesibini. I-network ye-Leri ye-Leri, okwangoku, inika isivinini phakathi kwama-5 Mbps kunye ne-12 Mbps.
Yintoni ezayo elandelayo?
I-5G iza emva koko, kunjalo. Ngaphambi kokuba uyazi, iinkampani ezithatha amanethiwekhi e-WiMax kunye nee-LTE ziya kuthetha nge-teknoloji ye-IMT-Advanced, eya kuzisa i-5G ngesivinini. I-teknoloji ilindeleke ukuba ihambe ngokukhawuleza, ibe nemida embalwa efile kwaye iphele iifowuni zedatha kwiikontraka zeselula. Ukuqulunqwa kuya kuvela kwiindawo ezinkulu zasezidolophini.
