**I-5G (NR) Amasistimu namanethiwekhi**
Ubuchwepheshe be-5G bamukela i-architecture eguquguqukayo nemodular kunezizukulwane zangaphambili zenethiwekhi yamaselula, okuvumela ukwenziwa ngokwezifiso okukhulu kanye nokwenza kahle kwezinsizakalo zenethiwekhi nemisebenzi.Amasistimu e-5G aqukethe izingxenye ezintathu ezibalulekile: i-**RAN** (Inethiwekhi Yokufinyelela Umsakazo), i-**CN** (Inethiwekhi Eyisisekelo) kanye Nezinethiwekhi Zomphetho.
- I-**RAN** ixhuma amadivaysi eselula (ama-UE) kunethiwekhi eyinhloko ngobuchwepheshe obuhlukahlukene obungenawaya obufana ne-mmWave, i-Massive MIMO, kanye nokwenza i-beamforming.
- I-*Core Network (CN)** inikeza ukulawula okubalulekile nemisebenzi yokuphatha njengokufakazela ubuqiniso, ukuhamba, kanye nemizila.
- **I-Edge Networks** ivumela izinsiza zenethiwekhi ukuthi zibekwe eduze kwabasebenzisi namadivayisi, ivumela izinsiza zokubambezeleka eziphansi kanye ne-high-bandwidth njenge-cloud computing, i-AI, ne-IoT.
Amasistimu e-5G (NR) anezakhiwo ezimbili: **NSA** (Non-Standalone) kanye ne-**SA** (Izimele):
- **NSA** isebenzisa ingqalasizinda ekhona ye-4G LTE (eNB ne-EPC) kanye namanodi amasha e-5G (gNB), esebenzisa inethiwekhi eyinhloko ye-4G ngemisebenzi yokulawula.Lokhu kusiza ukwakhiwa kokuthunyelwa kwe-5G okusheshayo kumanethiwekhi akhona.
- **SA** inesakhiwo esimsulwa se-5G esinenethiwekhi ewumgogodla ye-5G entsha sha kanye namasayithi eziteshi eziyisisekelo (gNB) aletha amakhono aphelele e-5G njengokulibaziseka okuphansi nokusika kwenethiwekhi.Umehluko obalulekile phakathi kwe-NSA ne-SA usekuncikeni kwenethiwekhi okuyisisekelo kanye nendlela yokuziphendukela kwemvelo - i-NSA iyisisekelo sezakhiwo ezithuthuke kakhulu, ezizimele ze-SA.
**Izinsongo Zezokuphepha Nezinselele **
Ngenxa yokwanda kobunzima, ukuhlukahluka kanye nokuxhumana, ubuchwepheshe be-5G bethula izinsongo ezintsha zokuphepha nezinselele kumanethiwekhi angenantambo.Isibonelo, izakhi zenethiwekhi eziningi, izixhumanisi zokusebenzelana nezivumelwano zingase zisetshenziswe abadlali abanonya njengabagebengu be-inthanethi noma izigebengu ze-inthanethi.Izinkampani ezinjalo zivame ukuzama ukuqoqa nokucubungula amanani akhulayo edatha yomuntu siqu nebucayi evela kubasebenzisi namadivayisi ngezinjongo ezisemthethweni noma ezingekho emthethweni.Ngaphezu kwalokho, amanethiwekhi e-5G asebenza endaweni enamandla kakhulu, okungenzeka abangele izinkinga zokulawula nokuhambisana kubaqhubi beselula, abahlinzeki besevisi nabasebenzisi njengoba kufanele bahambisane nemithetho ehlukahlukene yokuvikela idatha kuwo wonke amazwe kanye namazinga okuphepha enethiwekhi aqondene nomkhakha othile.
**Izixazululo Nezinyathelo Zokulwa**
I-5G ihlinzeka ngokuvikeleka okuthuthukisiwe nobumfihlo ngokusebenzisa izixazululo ezintsha ezifana nokubethela okuqinile nokuqinisekisa, i-edge computing kanye ne-blockchain, i-AI nokufunda ngomshini.I-5G isebenzisa i-algorithm yenoveli yokubethela ebizwa ngokuthi **5G AKA** esekelwe ekubhalweni kwe-elliptic curve, iletha iziqinisekiso zokuphepha eziphakeme.Ukwengeza, i-5G isebenzisa uhlaka olusha lokuqinisekisa olubizwa ngokuthi **5G SEAF** ngokusekelwe ekusikeni kwenethiwekhi.I-Edge computing ivumela idatha ukuthi icutshungulwe futhi igcinwe onqenqemeni lwenethiwekhi, kuncishiswe ukubambezeleka, umkhawulokudonsa kanye nokusetshenziswa kwamandla.Ama-Blockchains adala futhi aphathe amaleja asabalalisiwe, ahlukaniselwe futhi aqinisekise imicimbi yenethiwekhi.I-AI nokufunda komshini kuhlaziya futhi kubikezele amaphethini enethiwekhi nokudidayo ukuze kutholwe ukuhlaselwa/imicimbi futhi kukhiqize/kuvikele idatha yenethiwekhi nobunikazi.
I-Chengdu Concept Microwave Technology CO., Ltd ingumkhiqizi ochwepheshile wezingxenye ze-5G/6G RF e-China, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/i-band stop filter, i-duplexer, i-Power divider kanye ne-directional coupler.Zonke zingenziwa ngezifiso ngokuya ngezidingo zakho.
