- Cov kev sib nrig sib pab tsawg: Hauv cov hlua loj, cov kev sib nrig sib pab cuam tshuam ntawm cov kav hlau txais xov, thiab kev ntsuas yuav tsum tau coj los txo cov kev sib txuas lus zoo.
2. Massive Mimo Technology
Loj MIMO yog ib qho ntawm cov cores ntawm 5G thev naus laus zis. Los ntawm kev npaj ntau tus kav hlau txais xov arrays ntawm lub hauv paus chaw nres tsheb, lub peev xwm thiab kev ntseeg tau ntawm lub kaw lus tuaj yeem txhim kho tau zoo. Lub hauv paus chaw nres tsheb kav hlau txais xov yuav tsum tau txhawb nqa cov haujlwm hauv qab no:
- Multi-channel kis tau tus mob: muaj peev xwm ua tau ntau yam kev ywj pheej teeb liab channel nyob rau tib lub sij hawm kom ua tau zoo sib xws.
- Beam forming: Los ntawm kev kho cov theem thiab amplitude ntawm txhua chav nyob rau hauv lub kav hlau txais xov array, ib tug beam coj mus rau ib tug tshwj xeeb cov neeg siv yuav tsim tau los txhim kho lub teeb liab efficiency thiab tiv thaiv kev cuam tshuam.
- Kev kho kom haum: Muaj peev xwm hloov kho cov kav hlau txais xov tsis zoo thiab ua kom zoo dua cov teeb liab kis tau tus mob raws li kev hloov pauv ib puag ncig thiab cov neeg siv xav tau.
3. Beamforming thiab Beam Nrhiav
Beamforming technology can form a concentrated radiation beam in a specific direction by adjusting the signal phase and amplitude of each unit in the antenna array, improving signal transmission efficiency. Beam treming thev naus laus zis tuaj yeem kho cov kev taw qhia ci thaum tus neeg siv tau hloov mus rau kev sib txuas ruaj khov.
- Beamforming: Los ntawm kev suav cov theem zoo tshaj plaws thiab amplitude kev sib xyaw ua ke, lub nqaj qhia rau tus neeg siv tshwj xeeb yog tsim los txo kev cuam tshuam thiab txhim kho cov teeb liab zoo.
- Beam taug qab: Siv cov algorithms siab heev thiab cov cuab yeej sensor los saib xyuas tus neeg siv txoj haujlwm thiab kev txav mus los ntawm lub sijhawm tiag tiag, thiab hloov kho lub teeb pom kev taw qhia kom paub meej cov teeb liab txuas ntxiv thiab ruaj khov.
4. Kav hlau txais xov ua ke
Txhawm rau hloov mus rau cov kab hluav taws xob siab thiab MIMO qhov xav tau loj ntawm 5G thev naus laus zis, lub hauv paus chaw nres tsheb kav hlau txais xov yuav tsum tau tsim nyob rau hauv ib qho kev sib koom ua ke rau kev sib koom ua ke ntawm cov kav hlau txais xov, xov tooj cua zaus module thiab teeb liab ua haujlwm los tsim kom muaj kev sib cog lus thiab ua haujlwm tau zoo.
- Kev sib xyaw ua ke: Muab cov kav hlau txais xov nrog lub xov tooj cua zaus module thiab teeb liab ua haujlwm kom txo tau cov teeb liab kis tau tus mob thiab txhim kho kev ua haujlwm zoo.
- Modular: Modular tus qauv yog saws los pab txhawb kev teeb tsa, kev txij nkawm thiab txhim kho kom haum rau cov kev xav tau ntawm txawv scararios.
5. Txawj Ntse thiab Kev Hloov Kho
5G Chav Hauv Khw Antennas yuav tsum muaj cov ntse thiab hloov kho cov kav hlau txais xov thiab ua kom cov kev hloov teeb liab ib puag ncig thiab cov neeg siv xav tau.
- Ntse: siv cov kev txawj ntse thev naus laus zis kom paub txog kev txhim kho kom zoo dua los txhim kho qib kev txawj ntse ntawm lub system ntse.
- Kev hloov kho kom haum: Muaj peev xwm hloov kho cov kav hlau txais xov tsis zoo raws li kev hloov pauv ib puag ncig thiab cov neeg siv xav tau, ua kom zoo dua cov teeb liab kis tau tus mob, thiab txhim kho qhov yooj yim thiab yoog raws.
6. Kev siv cov khoom siv tshiab thiab cov thev naus laus zis tshiab
Txhawm rau yoog kom haum rau cov pawg high-zaus thiab loj mimo yuav tsum tau siv cov ntaub ntawv tshiab thiab thev naus laus zis tshiab los txhim kho kev ua haujlwm thiab kev ntseeg tau ntawm cov kav hlau txais xov.
- Cov ntaub ntawv tshiab: Siv cov ntaub ntawv ua haujlwm siab, xws li metamaterials, graphene, los txhim kho qhov nce, bandwidth thiab anti-cuam tshuam muaj peev xwm ntawm tus kav hlau txais xov ntawm lub kav hlau txais xov ntawm lub kav hlau txais xov ntawm lub kav hlau txais xov.
- Cov thev naus laus zis tshiab: Siv cov thev naus laus zis tsim khoom thiab cov txheej txheem, xws li 3D luam ntawv, microelectromechanical systems (MEMS), thiab lwm yam, txhawm rau txhim kho qhov tseeb thiab kev ntseeg siab ntawm lub kav hlau txais xov.
Txhawm rau suav, 5G Technology tau tso rau tom ntej cov kev cai tshiab rau cov khw muag khoom tshiab, uas yuav tsum tau them tus kav hlau loj, muaj tswv yim txhim kho, thiab cov ntaub ntawv tshiab thiab tshiab thev naus laus zis Cov. Kev tsim kho thiab txhim kho hauv kev thov thiab lwm yam. Los ntawm cov kev ntsuas no, cov khw muag khoom hauv paus yuav hloov kho rau kev txhim kho ntawm 5g thev naus laus zis thiab txhim kho kev ua haujlwm thiab kev ntseeg tau ntawm cov khoom sib txuas lus wireless.
