Niaj hnub no txoj kev nrhiav tau sai heev hnub nyoog,Xov tooj ntawm tes daim teeb liabUa si lub luag haujlwm tsis tseem ceeb yog cov khoom tseem ceeb hauv cov teb sib txuas lus. Txawm nyob hauv nroog loj hauv nroog lossisTej thaj chaw deb nroog, qhov kev ruaj ntseg thiab kev ua tau zoo ntawm lub xov tooj ntawm tes teeb liab yog qhov tseem ceeb uas cuam tshuam rau tib neeg lub neej zoo. Nrog rau cov dav dav kev saws cov thev naus lausli zoo li 5g thiab Is Taws Nem ntawm yam (ITO), qhov kev xav tau rau kev sib kis teeb liab tau nce zuj zus. Cov boosters teeb liab, nrog lawv lub peev xwm tshwj xeeb los txhim kho cov teeb liab muaj zog thiab nthuav tawm cov kev pab them nqi, tau dhau los ua cov kev daws teeb meem tseem ceeb rau kev daws teeb meem kev sib tw. Lawv tsis tsuas yog txhim kho kev sib txuas lus kev ua tau zoo thiab tseem muaj kev ruaj ntseg sib txuas lus thiab kev ruaj ntseg, muab kev yooj yim rau tib neeg lub neej txhua hnub thiab ua haujlwm.
Yuav ua li cas xaiv lub xov tooj ntawm tes cim liab qab rov ua dua?
1.Txoj kev teeb liab hom thiab zaus bands
Hom phiaj xwm: Thawj kauj ruam yog los txheeb xyuas hom teeb liab cellular thiab ntau zaus koj xav tau txhim kho.
Piv txwv li:
2G: GSM 900, DCS 1800, CDMA 850
3G: CDMA 2000, WCDMA 2100, Aws 1700
4G: DCS 1800, WCDMA 2100, LTE 2600, LTE 700, PCS 1900
5g: nr
Cov no yog qee zaus zaus. Yog tias koj tsis paub meej txog cov zaus siv nyiaj hauv koj thaj chaw, tiv tauj peb. Peb tuaj yeem pab koj txheeb xyuas lub zos cellular zaus.
2. Lub zog nce, tso zis zog, thiab thaj chaw pab ntawm xov tooj ntawm tes
Xaiv cov khoom siv hluav taws xob tsim nyog ntawm lub xov tooj ntawm tes teeb liab rov qab raws li qhov loj me uas koj yuav tsum txhim kho lub teeb liab. Feem ntau, me me rau cov chaw nyob nruab nrab lossis chaw ua haujlwm yuav xav tau qhov tsawg rau nruab nrab lub zog ntawm lub teeb liab. Rau thaj chaw loj dua lossis cov tsev lag luam ua lag luam, lub zog siab dua nce rov ua dua.
Lub xov tooj ntawm tes teeb liab lub nce thiab tso zis zog yog qhov tseem ceeb uas txiav txim siab nws cov cheeb tsam pov hwm. Ntawm no yog li cas lawv sib hais thiab cuam tshuam rau cov kev pab them nqi:
Ntsev KW23C Cell Xov tooj Teshauj Tes
San-as muaj zog
Zaj piav: Lub zog nce yog tus nqi uas cov roj teeb Amplifies cov teeb liab tawm tswv yim, ntsuas hauv Decibels (DB).
Hloov: Tau txais txiaj ntsig ntau dua txhais tau tias cov koob txhaj tshuaj tuaj yeem txhim kho cov cim tsis muaj zog, nce thaj chaw pov hwm.
Cov tseem ceeb: Cov kev txhawb nqa hauv tsev feem ntau muaj qhov nce ntawm 50-70 dB, thaumKev Lag Luam thiab Kev Lag Luam Kev Lag Luamtuaj yeem nce ntawm 70-100 dB.
· Tso zis ntau zog
Zaj piav: Tso zis lub zog yog lub zog ntawm teeb liab cov outter, ntsuas hauv milliwatts (MW) lossis decibel-milliwatts (DBM).
Hloov: Cov zis ntau lub zog txhais tau tias cov kev txhawb nqa tau tuaj yeem xa cov cim kom muaj zog, nkag rau phab ntsa tuab thiab npog ntau qhov deb.
Cov tseem ceeb: Cov kev txhawb nqa hauv tsev feem ntau muaj cov zis lub zog ntawm 20-30 dBM, thaum ua lag luam thiab kev lag luam tuaj yeem muaj cov zis siv zog ntawm 30-50 dBM.
· Pab tiv thaiv thaj chaw
Kev sib txheeb: Nce thiab tso zis zog ua ke txiav txim cov koob tshuaj tiv thaiv kab mob. Feem ntau, 10 dB nce ntxiv nyob rau hauv cov nce yog sib npaug rau kev nce qib nce hauv qhov tso zis ntau, nthuav dav ntawm thaj chaw pov hwm.
Tiag tiag-ntiaj teb cuam tshuam: Cov chaw pab them nqi tiag tiag tseem muaj feem los ntawm cov txheej txheem ib puag ncig xws li cov qauv tsim tsev thiab cov khoom sib cuam tshuam, cov kav hlau txais xov, thiab hom.
· Xav txog thaj chaw pab them nqi pov hwm
Ib puag ncig tsev: Ib hom kev tshuaj ntsuam hauv tsev (nrog rau qhov nce ntawm 50-70 dB thiab tso zis zog ntawm 20-30 dBM) tuaj yeem npog 2,000-5,000 square feet (kwv yees li ntawm 186-465 square meters).
Kev Lag Luam Ib puag ncig: Ib qho kev lag luam teeb tsa kev lag luam (nrog rau qhov nce ntawm 70-100 dB thiab tso zis lub zog ntawm 30-50 dBM) tuaj yeem npog 10,000-20,000 square feet (kwv yees li 929-1,858 square meters) lossis ntau dua.
Piv txwv
Tsawg tau nce thiab tsawg zis zog:
YES: 50 DB
Tso zis Lub Zog: 20 dbm
Cov Cheeb Tsam Kev Pab Them: Nyob ib ncig ntawm 2,000 Square Feet (kwv yees li 186 ㎡)
Siab nce thiab siab tso zis zog:
Tau: 70 dB
Tso zis Hwj chim: 30 dbm
Cov Cheeb Tsam Kev Pab Them: Nyob ib ncig ntawm 5,000 Square Taw (kwv yees li 465 ㎡)
KW35 Haib Mobile Xov tooj Rov Ua Lag Luam rau Cov Tsev Lag Luam
Lwm yam kev txiav txim siab
Kav hlau txais xov thiab kev tso kawm: Hom, Qhov chaw, thiab qhov siab ntawm lub xub ntiag sab nraud thiab sab hauv kav hlau txais xov yuav cuam tshuam cov teeb liab kev pov hwm.
Cov nyom: Phab ntsa, rooj tog zaum, thiab lwm yam kev khuam siab tuaj yeem txo cov teeb liab kev pab cuam, yog li kev ua kom zoo raws li cov xwm txheej tiag tiag.
Zaus bands: Txawv zaus bands muaj cov peev xwm sib txawv. Cov ntsiab lus qis dua cov cim (zoo li 700 MHz) feem ntau txeem cov cim zoo dua, thaum muaj 2100 MHz) npog me me.
Zuag qhia tag nrho, nce thiab tso zis zog yog qhov tseem ceeb hauv kev txiav txim siab thaj tsam ntawm lub teeb liab, tab sis muaj cov cuab yeej siv hluav taws xob ib puag ncig thiab cov cuab yeej teeb tsa rau kev pab them nyiaj zoo.
Yog tias koj tsis paub tseeb txog kev xaiv ibXov tooj ntawm tes teeb liab liab qab, thov hu rau peb. Peb pab neeg ntawm cov neeg siv khoom yuav muab koj sai sai rau koj nrog cov paib cellular teeb liab thiab cov lus sau tsim nyog.
3.Choosing hom thiab cov khoom lag luam
Thaum koj paub hom khoom twg uas koj xav tau, cov kauj ruam kawg yog xaiv cov khoom lag luam zoo thiab hom. Raws li kev txheeb cais, ntau dua 60% ntawm lub xov tooj ntawm tes liab qab thoob ntiaj teb yog tsim hauv Guangdong xeev, Suav, vim nws lub peev xwm muaj kev muaj peev xwm tshaj plaws.
Lub xov tooj ntawm tes zoo rov ua dua tshiab yuav tsum muaj cov hauv qab no:
· Cov khoom dav dav thiab ua tau zoo heev
Las sabTau nyob hauv lub xov tooj ntawm tes liab kev lag luam rau ntau tshaj 12 xyoos thiab muab cov khoom lag luam dav dav uas muaj txhua yam los ntawm cov tsev me me rau cov txheej txheem loj DAS.
Kuaj thiab kuaj qhov tsis sib xws
Cov khoom lag luam lasntawv yauv tsis ruaj khov, dej nyab, thiab kev sim ua kom ntseeg tau thiab kev ua tau zoo.
· Ua raws li cov kev cai thiab cov cai
Pem ncauj lus xov tooj ntawm tes tau xa tawm mus rau ntau tshaj 155 lub teb chaws, thiab lawv tau txais kev nyab xeeb thiab FCC, CE, ROHS, thiab lwm yam).
· Expandability thiab hloov chaw
Cov pab pawg ntsuas cov txuj ci tuaj yeem tsim kev nthuav dav thiab hloov kho cov kev daws teeb meem raws cov nqi siv tau los ntawm cov thev naus laus zis hloov zuj zus.
· Kev saib xyuas thiab kev pab cuam tom qab muag
Las sabMuaj pab pawg neeg txuj ci thiab tom qab muag kev pab cuam ntawm ntau tshaj 50 leej neeg, npaj kom tau raws li koj cov kev xav tau txhua lub sijhawm.
· Tej rooj plaub thiab kev ua tiav
Linttratek muaj kev paub ntau nrog cov haujlwm loj. Lawv cov tshuab kws tshaj lij yog siv hauv cov chaw ua si, chaw ntiav pw, chaw yuav khoom loj, chaw ua haujlwm, chaw ua liaj ua teb, thiab chaw deb.
