**5G (NR) Systems uye Networks**
5G tekinoroji inotora yakawedzera kuchinjika uye modular architecture kupfuura yapfuura cellular network zvizvarwa, zvichibvumira kukuru kugadzirisa uye optimization yetiweki masevhisi nemabasa.5G masisitimu anoumbwa nezvinhu zvitatu zvakakosha: iyo **RAN** (Radio Access Network), iyo **CN** (Core Network) uye Edge Networks.
- Iyo **RAN** inobatanidza nharembozha (UEs) kune yakakosha network kuburikidza neakasiyana mawaya tekinoroji senge mmWave, Massive MIMO, uye beamforming.
-Iyo ** Core Network (CN)** inopa kiyi yekutonga uye manejimendi mabasa senge chokwadi, kufamba, uye nzira.
- **Edge Networks ** inobvumira zviwanikwa zvetiweki kuti zviwanikwe padyo nevashandisi nemidziyo, zvichiita kuti yakaderera-latency uye yakakwirira-bandwidth masevhisi senge cloud computing, AI, uye IoT.
5G (NR) masisitimu ane maviri ekuvaka: **NSA** (Isiri-yakamira) uye **SA** (Yakamira):
- **NSA** inoshandisa iripo 4G LTE zvivakwa (eNB neEPC) pamwe ne5G node itsva (gNB), inosimudzira 4G core network yekutonga mabasa.Izvi zvinofambisa kukurumidza 5G yekuendesa chivakwa pane iripo network.
- **SA** ine yakachena 5G chimiro chine nyowani 5G musimboti network uye base station nzvimbo (gNB) inopa yakakwana 5G kugona senge yakaderera latency uye network slicing.Misiyano mikuru pakati peNSA neSA iri mukutsamira kwenetiweki uye nzira yekushanduka-shanduka - NSA ndiyo yekutanga yeakanyanya advanced, standalone SA architecture.
**Kutyisidzirwa uye Zvinetso **
Nekuda kwekuwedzera kuomarara, kusiyanisa uye kubatana, matekinoroji e5G anounza kutyisidzira kutsva kwekuchengetedza uye matambudziko kune isina waya network.Semuyenzaniso, zvimwe zvinhu zvenetiweki, mainterface nemaprotocol zvinogona kushandiswa nevaiti vane hutsinye vakaita sevanoba kana macybercriminals.Mapato akadaro anowanzo edza kuunganidza nekugadzirisa huwandu hwehuwandu hwemunhu uye hunonzwisiswa kubva kuvashandisi nemidziyo yezvikonzero zviri pamutemo kana zvisiri pamutemo.Uyezve, 5G network inoshanda munzvimbo ine simba, inogona kukonzera kudzora uye kutevedza nyaya kune vanofambisa nhare, vanopa masevhisi uye vashandisi sezvo vachifanira kutevedzera akasiyana mitemo yekudzivirira data munyika dzese uye indasitiri-yakanangana netiweki chengetedzo zviyero.
** Mhinduro uye Countermeasures **
5G inopa kuchengetedzeka kwakawedzera uye kuvanzika kuburikidza nemhinduro nyowani senge yakasimba encryption uye yechokwadi, edge komputa uye blockchain, AI uye muchina kudzidza.5G inoshandisa novel encryption algorithm inonzi **5G AKA** yakavakirwa pa elliptic curve cryptography, ichipa vimbiso dzepamusoro dzekuchengetedza.Pamusoro pezvo, 5G inokwirisa humbowo hutsva hwechokwadi hunodaidzwa kuti ** 5G SEAF ** zvichibva pakutemerwa netiweki.Edge komputa inobvumira dhata kuti igadziriswe uye kuchengetwa pamupendero wetiweki, kuderedza latency, bandwidth uye mashandisiro esimba.Blockchains inogadzira uye inogadzirisa yakagovaniswa, yakatemerwa ledgers kurekodha uye kusimbisa network transaction zviitiko.AI uye muchina kudzidza kuongorora uye kufanotaura network mapatani uye anomalies kuona kurwiswa / zviitiko uye kugadzira / kuchengetedza network data uye kuzivikanwa.
Chengdu Concept Microwave Technology CO., Ltd inyanzvi inogadzira zvinhu zve5G/6G RF kuChina, zvinosanganisira RF lowpass sefa, highpass filter, bandpass filter, notch filter/band stop filter, duplexer,Power divider uye directional coupler.Ese anogona kugadzirwa zvinoenderana nezvinodiwa zvako.
