**5G (NR) Systems and Networks**
5G thev naus laus zis tau txais kev hloov pauv tau yooj yim thiab cov qauv tsim qauv dua li yav dhau los ntawm cov xov tooj ntawm tes, tso cai rau kev hloov kho ntau dua thiab ua kom zoo dua ntawm cov kev pabcuam hauv network thiab kev ua haujlwm.5G systems muaj peb yam tseem ceeb: **RAN** (Xov tooj cua Access Network), ** CN ** (Core Network) thiab Edge Networks.
- Tus **RAN** txuas cov khoom siv mobile (UEs) mus rau cov tub ntxhais network los ntawm ntau yam wireless technologies xws li mmWave, Massive MIMO, thiab beamforming.
- Lub **Core Network (CN)** muab kev tswj xyuas thiab tswj cov haujlwm tseem ceeb xws li kev lees paub, kev txav mus los, thiab kev ua haujlwm.
- ** Edge Networks ** tso cai rau cov peev txheej hauv network kom nyob ze rau cov neeg siv thiab cov khoom siv, ua kom tsis tshua muaj latency thiab high-bandwidth cov kev pabcuam xws li huab xam, AI, thiab IoT.
5G (NR) systems muaj ob lub qauv: ** NSA ** (Non-Sandalone) thiab ** SA ** (Standalone):
- ** NSA ** siv 4G LTE infrastructure (eNB thiab EPC) uas twb muaj lawm 5G nodes (gNB), leveraging 4G core network rau kev tswj kev ua haujlwm.Qhov no ua kom yooj yim dua 5G kev xa tawm lub tsev ntawm cov tes hauj lwm uas twb muaj lawm.
- ** SA ** muaj cov qauv 5G ntshiab nrog cov cim tshiab 5G core network thiab cov chaw nres tsheb hauv paus (gNB) xa ua tiav 5G peev xwm zoo li qis dua latency thiab network slicing.Qhov sib txawv tseem ceeb ntawm NSA thiab SA yog nyob rau hauv cov tub ntxhais network dependence thiab evolutionary txoj kev - NSA yog lub hauv paus rau lub siab tshaj, standalone SA architecture.
** Kev Nyab Xeeb Kev Nyab Xeeb thiab Kev Nyuaj Siab **
Vim muaj kev nyuaj siab ntau ntxiv, muaj ntau haiv neeg thiab kev sib tshuam, 5G thev naus laus zis qhia txog kev hem thawj kev nyab xeeb tshiab thiab cov teeb meem nyuaj rau cov tes hauj lwm wireless.Piv txwv li, ntau lub ntsiab lus network, kev sib txuas thiab cov txheej txheem tuaj yeem siv los ntawm cov neeg ua phem phem xws li hackers lossis cybercriminals.Cov tog neeg no feem ntau sim sau thiab ua cov ntaub ntawv ntawm tus kheej thiab cov ntaub ntawv rhiab heev los ntawm cov neeg siv thiab cov khoom siv rau lub hom phiaj raug cai lossis tsis raug cai.Tsis tas li ntawd, 5G tes hauj lwm ua haujlwm nyob rau hauv ib qho chaw muaj zog dua, muaj peev xwm ua rau muaj teeb meem kev tswj hwm thiab kev ua raws cai rau cov neeg siv xov tooj ntawm tes, cov chaw muab kev pabcuam thiab cov neeg siv vim lawv yuav tsum ua raws li cov cai sib txawv ntawm cov ntaub ntawv tiv thaiv thoob plaws lub tebchaws thiab cov qauv kev lag luam tshwj xeeb network kev ruaj ntseg.
** Kev daws teeb meem thiab Countermeasures **
5G muab kev ruaj ntseg thiab kev ceev ntiag tug los ntawm cov kev daws teeb meem tshiab xws li muaj zog encryption thiab authentication, ntug kev suav thiab blockchain, AI thiab kev kawm tshuab.5G ntiav tus tshiab encryption algorithm hu ua **5G AKA** raws li elliptic nkhaus cryptography, xa cov kev ruaj ntseg zoo tshaj.Tsis tas li ntawd, 5G leverages ib tug tshiab authentication moj khaum hu ua **5G SEAF** raws li network slicing.Edge xam tso cai rau cov ntaub ntawv ua tiav thiab khaws cia ntawm lub network ntug, txo latency, bandwidth thiab kev siv hluav taws xob.Blockchains tsim thiab tswj cov kev faib tawm, decentralized ledgers kaw thiab validating network pauv xwm txheej.AI thiab tshuab kev kawm tshawb xyuas thiab kwv yees cov qauv kev sib txuas thiab kev tsis sib xws txhawm rau txheeb xyuas qhov kev tawm tsam / xwm txheej thiab tsim / tiv thaiv cov ntaub ntawv network thiab tus kheej.
Chengdu Concept Microwave Technology CO., Ltd yog cov chaw tsim khoom lag luam ntawm 5G / 6G RF Cheebtsam hauv Suav teb, suav nrog RF lowpass lim, highpass lim, bandpass lim, notch filter / band nres lim, duplexer, Fais fab divider thiab directional coupler.Tag nrho lawv tuaj yeem kho raws li koj qhov kev xav tau.
