Nyob rau hauv ib puag ncig kaw xws li tunnels thiab hauv qab daus, wireless signals feem ntau cuam tshuam loj heev, ua rau cov khoom siv sib txuas lus xws li xov tooj ntawm tes thiab wireless network tsis ua haujlwm zoo. Yuav kom daws tau qhov teeb meem no, engineers tau tsim ntau yam teeb liab amplification li. Cov khoom siv no tuaj yeem tau txais cov cim tsis muaj zog wireless thiab nthuav dav, ua rau cov khoom siv wireless ua haujlwm ib txwm nyob hauv ib puag ncig kaw. Hauv qab no, peb yuav qhia qee cov khoom siv hluav taws xob ua kom nrov nrov siv hauv qhov av thiab hauv qab daus.
1. Distributed Antenna System (DAS)
Kev faib cov kav hlau txais xov yog ib qho kev siv cov teeb liab amplification tswv yim, uas qhia tawm sab nraum zoov wireless teeb liab mus rau hauv ib puag ncig sab hauv tsev los ntawm kev txhim kho ntau lub kav hlau txais xov hauv tunnels thiab hauv qab daus, thiab tom qab ntawd nthuav tawm thiab nthuav tawm cov teeb liab wireless los ntawm cov kav hlau txais xov. Lub DAS system tuaj yeem txhawb nqa ntau tus neeg ua haujlwm thiab ntau lub zog ntau zaus, thiab tsim nyog rau ntau yam kev sib txuas lus wireless, suav nrog 2G, 3G, 4G, thiab 5G.
2. Tau txais hom teeb liab amplifier
Qhov nce hom teeb liab amplifier ua tiav cov teeb liab kev pab cuam los ntawm kev txais thiab amplifying tsis muaj zog wireless signals, thiab tom qab ntawd xa lawv dua. Cov cuab yeej no feem ntau muaj lub kav hlau txais xov sab nraum zoov (tau txais cov teeb liab), lub teeb liab amplifier, thiab ib lub kav hlau txais xov sab hauv (kev xa cov teeb liab). Qhov nce hom teeb liab amplifier yog tsim rau me me hauv qab daus thiab tunnels.
3. Fiber optic repeater system
Fiber optic regeneration system yog ib tug high-end teeb liab amplification kev daws teeb meem uas converts wireless signals rau hauv optical signals, uas yog ces kis mus rau hauv av los yog nyob rau hauv lub tunnels los ntawm optical fibers, thiab ces hloov rov qab mus rau wireless signals los ntawm fiber optic receivers. Qhov kom zoo dua ntawm cov kab ke no yog tias nws muaj cov teeb liab kis tau tus mob tsawg thiab tuaj yeem ua tiav cov teeb liab sib kis mus ntev thiab kev pab them nqi.
4. Me Cell
Lub chaw nres tsheb me me yog ib hom tshiab ntawm cov teeb liab amplification ntaus ntawv uas muaj nws tus kheej wireless kev sib txuas lus muaj peev xwm thiab tuaj yeem sib txuas lus ncaj qha nrog cov xov tooj ntawm tes thiab lwm yam khoom siv wireless. Cov chaw nres tsheb me me feem ntau yog ntsia rau ntawm lub qab nthab ntawm qhov tunnels thiab hauv qab daus, muab kev ruaj ntseg wireless teeb liab.
Cov saum toj no yog qee cov teeb liab amplification li siv nyob rau hauv tunnels thiab hauv qab daus. Thaum xaiv ib lub cuab yeej, nws yog ib qho tsim nyog yuav tau xav txog yam xws li cov kev xav tau kev pab them nqi tiag tiag, pob nyiaj siv, thiab kev sib raug zoo ntawm cov cuab yeej los xaiv cov cuab yeej tsim nyog tshaj plaws rau tus kheej.
