    KingTone Tetra DMR UHF 400MHz 450MHz Kab Amplifer BDA siv rau Sab Hauv Tsev Distributions System (IBS), Hauv qab daus, Qhov Kev Pabcuam

    qhov project design

    Sab Hauv Tsev Distributions System (IBS), Hauv qab daus, Qhov Kev Pabcuam Kev daws teeb meem:

    1. Kev soj ntsuam ntawm qhov chaw engineering: Puas yog lub hauv paus chaw nres tsheb teeb liab 380-400MHz?

    Lub xov tooj ntawm tes teeb liab ntawm qhov chaw nkag tau txais 3-4 cov teeb liab (teb lub zog yuav tsum tsawg kawg yog -85dBm lossis zoo dua)?Yog tias tsis yog, nrhiav qhov chaw nyob ze ntawm lub qhov av nrog cov teeb liab zoo raws li lub teeb liab tau txais;

    Lus Cim: Qhov chaw txais yuav tsum yog txoj hauj lwm ntawm tus kav hlau txais xov, tab sis nws tsis yog txoj hauj lwm ntawm tus repeater.Qhov kev ncua deb ntawm tus kav hlau txais xov mus rau lub repeater tsis txwv (tuaj yeem nyob ze lossis deb), thiab tus neeg siv khoom kho nws tus kheej raws li qhov project;

     

    2, kav hlau txais xov installation

    Lub repeater yuav muaj ob qhov chaw nres nkoj, qhov chaw nres nkoj BS txuas nrog lub kav hlau txais xov (mus rau qhov chaw nres tsheb hauv paus), thiab MS chaw nres nkoj txuas rau npog lub kav hlau txais xov (mus rau thaj chaw them nyiaj);

    Txawm li cas los xij, txhawm rau zam kom tsis txhob muaj qhov rov ua rau nws tus kheej, qhov rov ua haujlwm tsis tuaj yeem ua haujlwm (qhov kev ua rau tus kheej hnyav yuav ua rau lub zog rov ua kom lub zog rov ua dua), yog li ua tib zoo saib ob lub ntsiab lus hauv qab no:

    a, cov kav hlau txais xov thiab cov kav hlau txais xov npog yuav tsum rov qab mus rau sab nraub qaum;

    b, qhov kev ncua deb ntawm tus kav hlau txais xov thiab cov kav hlau txais xov npog yog tsawg kawg yog ntau tshaj 50 meters, thiab qhov kev ncua deb yog kho raws li qhov tseeb ntawm qhov chaw;

    c.Yog hais tias tus txheej txheem installation, qhov kev ncua deb ntawm ob lub kav hlau txais xov tau mus txog 80 meters los yog ntau tshaj, nws yog tsis yooj yim sua kom tsis txhob nws tus kheej excitation.Nws raug nquahu kom cov neeg siv khoom ntxiv ib qho kev sib cais ntawm ob lub kav hlau txais xov (xws li ib daim hlau loj) lossis siv cov xwm txheej ntawm qhov chaw mus rau lub kav hlau txais xov cais (xws li lub roob lossis lub tsev loj);

    3

    4, feeder & connector: 1/2 "coaxial cable, ntev: cov neeg muas zaub customize raws li qhov project xav tau!

    5, yog tias muaj ib lub ces kaum ntawm lub qhov, nws raug nquahu kom ntxiv ob lub hwj chim splitter rau lub repeater, rub lub feeder, thiab ntxiv lub kav hlau txais xov npog;
