Isevisi yeselula ye-4 isheshe izikhathi ezingu-10 kunesevisi ye-3G
I-wireless ye-4G igama elisetshenziselwa ukuchaza isitshalo sesine senkonzo yeselula engenantambo. I-4G isinyathelo esikhulu kusuka ku- 3G futhi ifika izikhathi ezingu-10 ngokushesha kunesevisi ye-3G. I-Sprint yiyena ophethe kuqala ukunikeza isivinini esingu-4G e-US kusukela ngo-2009. Manje bonke abathwali banikeza inkonzo ye-4G ezindaweni eziningi zezwe, nakuba ezinye izindawo zasemaphandleni zikhona kuphela ukufakwa kwe-3G kancane kancane.
Kungani 4G Speed Matters
Njengoba ama-smartphones namaphilisi ahlakulela ikhono lokusakaza ividiyo nomculo, isidingo sejubane sabaluleke kakhulu. Ngokomlando, ukuvinjelwa kwamaselula kwakuhamba kancane kunalokho okuhlinzekwa ukuxhumana okusheshayo kwe-broadband kumakhompyutha. Isivinini se-4G siqhathanisa kahle nezinye izinketho ze-broadband futhi ziwusizo ikakhulukazi ezindaweni ngaphandle kokuxhumeka kwe-broadband.
4G Technology
Ngenkathi yonke insizakalo ye-4G ibizwa ngokuthi i-4G noma i-4G LTE, ubuchwepheshe obuyisisekelo abufani nabo bonke abathintekayo. Abanye basebenzisa ubuchwepheshe be-WiMax ngenethiwekhi yabo ye-4G, kuyilapho i-Verizon Wireless isebenzisa ubuchwepheshe obubizwa nge-Long Term Evolution, noma i-LTE.
I-Sprint ithi inethiwekhi yayo ye-4G WiMax inikeza ngesivinini sokulanda esheshayo izikhathi eziyishumi kunokuxhumeka kwe-3G, ngesivinini esiphumela kuma-megabithi angu-10 ngomzuzwana. Inethiwekhi ye-Leri ye-Verizon okwamanje, inikeza isivinini phakathi kuka-5 Mbps no-12 Mbps.
Yini Ezayo Okulandelayo?
I-5G ilandelayo , yebo. Ngaphambi kokuthi wazi, izinkampani ezithinta amanethiwekhi we-WiMax ne-LTE zizokhuluma ngobuchwepheshe be-IMT-Advanced, obuzoletha isivinini esingu-5G. Ubuchwepheshe kulindeleke ukuba bube ngokushesha, babe nezindawo ezimbalwa ezifile futhi ugcine amasheya wedatha ezinkontileka zeselula. Ukuqalwa kuzoqala ezindaweni ezinkulu zasemadolobheni.
