AbakwaSamsung kanye ne-KT Corporation, phambilini obekuyiKorea Telecom, bamemezele ukuthi sebewaqedile amalungiselelo okuxhuma ubuchwepheshe be-5G. Zombili lezi zinkampani cishe zizoba ngezokuqala ukwethula ubuchwepheshe obusha bokudluliswa kweselula. Ngokolwazi lwethu, izokwethulwa kakade ngo-2018, lapho Imidlalo yama-Olimpiki Wasebusika izobanjelwa ePyongyang.
Ngakho-ke kusho ukuthi le ndawo izoba noxhumano lwasemoyeni nolomphakathi lwe-5G, ngokushesha kunalokho obekuhleliwe ekuqaleni. AbakwaSamsung kanye ne-KT Corporation bahlele ukwethula ubuchwepheshe obusha kuphela ngo-2020, lapho inethiwekhi ye-5G izofinyelela umphakathi. Noma kunjalo, ngezinga elikhulu, yonke into izoncika kubakhiqizi bamafoni ahlakaniphile noma amaphilisi, ama-chips, futhi ekugcineni kodwa abathwali abazothola ubuchwepheshe phakathi kwabanye.
Amakhasimende angabheka phambili isivinini esingafika kumagigabhithi ambalwa ngomzuzwana, hhayi ama-megabits. Isibonelo kungaba uhlelo lwe-TV olungalandwa ngaphansi kwamasekhondi amathathu. Amakhasimende nawo azothola ukubambezeleka okuphansi kakhulu. Ngakho kusho ukuthi ukudlala amavidiyo ku-YouTube nakwamanye amasevisi kuzoshesha kakhulu. Silindele ukubambezeleka kwe-5G kube sebangeni lama-millisecond angu-1-5.
Nokho, izisekelo cishe sezilungile. I-Qualcomm, i-chipmaker yeselula, inwebise amamodemu eselula e-X50 5G nabathwali, njengoba ibe ne-Verzion, T-Mobile, ne-US Cellular, eqale ukuhlolwa ngaphambili. Phakathi kwezinye izinto, i-Verzion ingumsunguli we-5G Open Trial Specification Alliance, ngenxa yezindinganiso zenethiwekhi ezivamile.
Khonamanjalo, i-Sprint ithi isivele inomthamo owanele olungele ukuthwala inani ledatha eliphindwe kathathu. Ubuchwepheshe beselula be-5G kufanele bunikeze isivinini sokudlulisa esifika ku-10 Gbps. Cishe ngo-2020, ukusetshenziswa kwedatha okuphezulu kakhulu kulindeleke, ngokunembile izikhathi ezingama-30 ukwedlula kuze kube manje.
Anjani amanethiwekhi angenantambo asekhaya?
Ngaphansi kweminyaka emibili edlule, i-ČTÚ (i-Czech Telecommunications Authority) ishicilele imephu entsha ngokuphelele yokuhlanganisa, esekelwe kumingcele yezobuchwepheshe yeziteshi eziyisisekelo zabasebenzi basekhaya. Ngenxa yalokhu, singathola ukuthi opharetha baseCzech baqhuba kanjani. Izinkampani zasekhaya zinomkhuba wokwengeza iphesenti elithile lokuhlanganisa, kodwa ngenxa ye-ČTÚ siyazazi izinombolo zangempela.
Imephu yamanje inikeza amabhendi okumboza amaningana - 800 MHz, 900 MHz, 1 MHz, 800 MHz kanye no-2 MHz. Phakathi kwezinye izinto, kukhona namanethiwekhi e-UMTS asebenza kubhendi engu-100 MHz.
I-O2 inendawo eningi embozwe uxhumo olunesivinini esikhulu. I-T-Mobile ibambelele ngesibindi endaweni yesibili ngenxa yokwabelana ngedatha phakathi kwe-O2 ne-T-Mobile. Indawo yesithathu ithathwe yiVodafone, engenzi kahle kakhulu. Kodwa-ke, kukhona nezindawo eziyimpumputhe lapho kungekho noyedwa wabaqhubi basekhaya onesiginali. Lezi kungaba yizindawo izinkampani ezingenantshisekelo kuzo. Okunye okungenzeka yizintaba eziphakeme, ezingase futhi zivimbele ukusetshenziswa okunethezeka kwe-4G-LTE.
Sizobubona nini ubuchwepheshe be-5G e-Czech Republic?
Ukufika kobuchwepheshe obusha kusezinkanyezini ngempela. Singalindela ukuhlolwa kokuqala endaweni yaseCzech Republic eminyakeni emihlanu. Ukuthi sizobona amanethiwekhi we-5G akuxhomekile kuphela kuma-opharetha asekhaya, kodwa futhi nasekuxhaseni ngemali evela e-EU, yona engabambi iqhaza njalo.
