**Izinhlelo namaNethiwekhi e-5G (NR)**
Ubuchwepheshe be-5G busebenzisa ukwakheka okuguquguqukayo nokwe-modular kunezizukulwane zangaphambilini zenethiwekhi yeselula, okuvumela ukwenza ngokwezifiso okukhulu nokwenza ngcono izinsizakalo nemisebenzi yenethiwekhi. Izinhlelo ze-5G zakhiwe izingxenye ezintathu ezibalulekile: i-**RAN** (Radio Access Network), i-**CN** (Core Network) kanye ne-Edge Networks.
- I-**RAN** ixhumanisa amadivayisi eselula (ama-UE) kunethiwekhi eyinhloko ngokusebenzisa ubuchwepheshe obuhlukahlukene obungenantambo njenge-mmWave, i-Massive MIMO, kanye ne-beamforming.
- I-**Core Network (CN)** inikeza imisebenzi ebalulekile yokulawula nokuphatha njengokuqinisekisa, ukuhamba, kanye nokuhambisa.
- **Ama-Edge Networks** avumela izinsiza zenethiwekhi ukuthi zibekwe eduze kwabasebenzisi namadivayisi, okuvumela izinsizakalo ze-low-latency kanye ne-bandwidth ephezulu njenge-cloud computing, i-AI, kanye ne-IoT.
Izinhlelo ze-5G (NR) zinezakhiwo ezimbili: **NSA** (Non-Standalone) kanye **SA** (Standalone):
- **I-NSA** isebenzisa ingqalasizinda ye-4G LTE ekhona (i-eNB ne-EPC) kanye nama-node amasha e-5G (gNB), isebenzisa inethiwekhi eyinhloko ye-4G ngemisebenzi yokulawula. Lokhu kwenza kube lula ukwakhiwa okusheshayo kokufakwa kwe-5G kumanethiwekhi akhona.
- **I-SA** inesakhiwo se-5G esihlanzekile esinenethiwekhi entsha ye-5G core kanye nezindawo zesiteshi sesisekelo (gNB) ezinikeza amakhono aphelele e-5G njengokulibaziseka okuphansi kanye nokusikwa kwenethiwekhi. Umehluko omkhulu phakathi kwe-NSA ne-SA usekuncikeni kwenethiwekhi eyinhloko kanye nendlela yokuziphendukela kwemvelo - i-NSA iyisisekelo sokwakheka kwe-SA okuthuthukisiwe, okuzimele.
**Izinsongo Nezinselele Zokuphepha**
Ngenxa yokwanda kobunzima, ukuhlukahluka kanye nokuxhumana, ubuchwepheshe be-5G buletha izinsongo ezintsha zokuphepha kanye nezinselele kumanethiwekhi angenantambo. Isibonelo, izakhi eziningi zenethiwekhi, izixhumi kanye nezinqubo zingasetshenziswa ngabantu abanonya njengabaphangi noma izigebengu ze-inthanethi. Amaqembu anjalo avame ukuzama ukuqoqa nokucubungula inani elikhulayo ledatha yomuntu siqu neyimfihlo evela kubasebenzisi namadivayisi ngezinjongo ezisemthethweni noma ezingekho emthethweni. Ngaphezu kwalokho, amanethiwekhi e-5G asebenza endaweni enamandla kakhulu, okungase kubangele izinkinga zomthetho kanye nokuhambisana nomthetho kubasebenzisi beselula, abahlinzeki bezinsizakalo kanye nabasebenzisi njengoba kumele banamathele emithethweni yokuvikela idatha ehlukahlukene kuwo wonke amazwe kanye nezindinganiso zokuphepha kwenethiwekhi ezithile embonini.
**Izixazululo kanye Nezindlela Zokulwa**
I-5G inikeza ukuphepha okuthuthukisiwe kanye nobumfihlo ngezixazululo ezintsha ezifana nokubethela okuqinile kanye nokuqinisekiswa, i-edge computing kanye ne-blockchain, i-AI kanye nokufunda komshini. I-5G isebenzisa i-algorithm entsha yokubethela ebizwa ngokuthi i-**5G AKA** esekelwe ku-elliptic curve cryptography, iletha iziqinisekiso zokuphepha eziphakeme. Ngaphezu kwalokho, i-5G isebenzisa uhlaka olusha lokufakazela olubizwa ngokuthi i-**5G SEAF** ngokusekelwe ekusikeni kwenethiwekhi. I-Edge computing ivumela idatha ukuthi icutshungulwe futhi igcinwe emngceleni wenethiwekhi, inciphise ukubambezeleka, i-bandwidth kanye nokusetshenziswa kwamandla. Ama-Blockchain adala futhi aphathe ama-ledger asatshalaliswayo, ahlukaniswe ngobuningi aqopha futhi aqinisekise imicimbi yokuthengiselana kwenethiwekhi. I-AI kanye nokufunda komshini kuhlaziya futhi kubikezele amaphethini enethiwekhi kanye nokungafani ukuze kutholakale ukuhlaselwa/imicimbi futhi kukhiqizwe/kuvikelwe idatha yenethiwekhi kanye nobunikazi.
I-Chengdu Concept Microwave Technology CO.,Ltd ingumkhiqizi ochwepheshe wezingxenye ze-5G/6G RF eShayina, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/band stop, i-duplexer, i-Power divider kanye ne-directional coupler. Zonke zingenziwa ngezifiso ngokwezidingo zakho.
