I-3G - Inethiwekhi yesithathu yeselula yeSithathu iguqule indlela esixhumana ngayo esebenzisa amadivayisi eselula. Amanethiwekhi we-4G athuthukiswa ngamanani angcono wedatha kanye nesipiliyoni somsebenzisi. I-5G izokwazi ukuhlinzeka nge-mobile Broadband kuze kube yi-10 gigabits ngomzuzwana ngokulandelana okuphansi kwama-milliseconds ambalwa.
Uyini umehluko omkhulu phakathi kwe-4G ne-5G?
Isivinini
Uma kufika ku-5G, ijubane yinto yokuqala wonke umuntu ajabule ngobuchwepheshe. Ubuchwepheshe obuthuthukisiwe be-LTE buyakwazi ukuthola isilinganiso sedatha kuze kufike ku-1 gbps kumanethiwekhi we-4G. Ubuchwepheshe be-5G buzosekela isilinganiso sedatha kuze kufike ku-5 kuya ku-10 gbps kumadivayisi eselula nangaphezulu kwama-20 gbps ngesikhathi sokuhlola.
I-5G ingasekela izinhlelo zokusebenza ezijulile zedatha efana nokusakazwa kwe-4K HD multimedia, okungokoqobo okungokoqobo (AR) kanye nezicelo ezingokoqobo zangempela (VR). Ngaphezu kwalokho, ngokusetshenziswa kwamagagasi ama-millimeter, isilinganiso sedatha singandiswa ngaphezulu kwama-40 gbps futhi kuze kufike ku-100 gbps kumanethiwekhi wesikhathi esizayo.
Amagagasi ama-millimeter ane-bandwidth eningi ebanzi uma iqhathaniswa nama-bandwidth Frequency band asetshenziswa kubuchwepheshe be-4G. Nge-bandwidth ephezulu, kuphakama isilinganiso sedatha.
Indawo yokuhlinza
I-Latency igama elisetshenziswe kubuchwepheshe benethiwekhi ukukala ukubambezeleka kwamaphakethe wesiginali afinyelela endaweni eyodwa kuya kokunye. Kumanethiwekhi eselula, kungachazwa njengesikhathi esithathwa yizimpawu zomsakazo ukuze uhambe usuka esiteshini sesisekelo uye kumadivayisi eselula (uE) nokuphikisana nalokho.
I-latency yenethiwekhi ye-4G isezingeni lama-millisecond angama-200 kuye kwayi-100. Ngesikhathi sokuhlolwa kwe-5G, onjiniyela bakwazi ukufeza futhi babonise i-latency ephansi yama-1 kuye kwangama-3 millisecond. I-latency ephansi ibaluleke kakhulu kwizicelo eziningi ezibucayi bemishini futhi ngenxa yalokho ubuchwepheshe be-5G ilungele izinhlelo eziphansi ze-latency.

Ubuchwepheshe obuthuthukisiwe
Ukuze uzuze izinsizakalo ze-Latency ezisheshayo ze-Ultra-ezisheshayo futhi eziphansi, i-5G kufanele zisebenzise ama-terminologies athuthukile afana nama-milimeter waves, i-mimo, i-beangforming, idivaysi ekuxhumaneni kwedivayisi kanye nemodi ephelele ye-duplex nemodi ephelele ye-Dumplex.
Ukulayishwa kwe-Wi-Fi nakho kungenye indlela ephakanyisiwe ku-5G ukukhulisa ukusebenza kahle kwedatha futhi kunciphise umthwalo eziteshini ezisezisesizini. Amadivayisi eselula angaxhuma kwi-LAN engenantambo etholakalayo futhi asebenze yonke imisebenzi (izwi nedatha) esikhundleni sokuxhuma iziteshi eziyisisekelo.
Ubuchwepheshe be-4G ne-LTE Advanced Technology busebenzisa amasu wokushintshashintsha afana ne-Quadreature Amplitude Modation (Qam) kanye ne-QuadRedatur Stase-Shift Key (QPSK). Ukuze unqobe eminye imikhawulo ezinhlelweni zokushintshana kwe-4G, inqubo ephakeme ye-Amplitude State-Shift Ukushisa inqubo kungenye yokucatshangelwa kobuchwepheshe be-5G.
Isakhiwo senethiwekhi
Ezizukulwaneni zakudala zamanethiwekhi weselula, amanethiwekhi wokufinyelela umsakazo atholakala eduze kwesiteshi sesisekelo. Abantu bendabuko bayinkimbinkimbi, bekudingeka ingqalasizinda ebizayo, ukulungiswa ngezikhathi ezithile kanye nokusebenza okulinganiselwe.
Ubuchwepheshe be-5G buzobe busebenzisa i-Cloud Radio Fice Network (C-Ran) ukusebenza kahle okungcono. Abasebenza nge-Network banganikela nge-inthanethi esheshayo e-Ultra-Fast kusuka ku-Cound Centrate Floud VACE Access Network.
I-Intanethi Yezinto
I-Inthanethi yezinto ingenye isikhathi esikhulu esivame ukuxoxa nobuchwepheshe be-5G. I-5G izoxhuma izigidigidi zamadivayisi nezinzwa ezihlakaniphile kwi-Intanethi. Ngokungafani ne-4G Technology, inethiwekhi ye-5G izokwazi ukuphatha ivolumu enkulu yedatha kusuka kuzinhlelo eziningi ezifana nekhaya elihle, i-Industrial Iot, amadolobha ahlakaniphile, amadolobha ahlakaniphile njll.
Okunye ukusetshenziswa okukhulu kwe-5G kuwumshini wohlobo lomshini wokuxhumana. Izimoto ezizimele zizobe zilawula imigwaqo yesikhathi esizayo ngosizo lwezinsizakalo ezithuthukile ze-latency 5g.
I-Marlow Band - I-Intanethi Yezinto (NB - Iot) application (NB - Iot) enjenge-smart lighting, amamitha ahlakaniphile, nezixazululo zokupaka ama-smart, imephu yesimo sezulu izothunyelwa kusetshenziswa inethiwekhi ye-5G.
Izixazululo ezithembekile ze-Ultra
Uma kuqhathaniswa ne-4G, amadivaysi e-5G wesikhathi esizayo azonikela ngaso sonke isikhathi axhunyiwe, izixazululo ezinokwethenjelwa ezinokwethenjelwa futhi ezisebenza kahle kakhulu. I-Qualcomm isanda kumbuliswa imodemu yabo ye-5G yamadivayisi ahlakaniphile namakhompyutha uqobo.
I-5G izokwazi ukuphatha ivolumu enkulu yedatha kusuka ezigidini zamadivayisi bese kuthi inethiwekhi yenzelwe ukuthuthukiswa. Amanethiwekhi we-4G namanje we-LTE anomkhawulo ngokuya ngevolumu yedatha, isivinini, i-latency kanye nokukhubazeka kwenethiwekhi. Ubuchwepheshe be-5G bazokwazi ukubhekana nalezi zinkinga futhi banikeze ngezixazululo ezisebenzayo ezisebenzayo kubahlinzeki bezinsizakalo nabasebenzisi bokugcina.
