Kingtone Repeaters system yog tsim los daws cov teeb meem ntawm cov teeb liab tsis muaj zog ntawm lub xov tooj ntawm tes, uas yog pheej yig dua li kev ntxiv qhov chaw nres tsheb tshiab (BTS).Lub luag haujlwm tseem ceeb ntawm RF Repeaters system yog kom tau txais cov teeb liab hluav taws xob tsawg los ntawm BTS los ntawm kev xa xov tooj cua zaus thiab tom qab ntawd xa cov teeb liab amplified mus rau thaj chaw uas tsis muaj kev pab cuam network.Thiab lub teeb liab ntawm lub xov tooj ntawm tes kuj tau nthuav dav thiab xa mus rau BTS ntawm qhov kev coj ua.

Cov yam ntxwv tseem ceeb ntawm repeater:
1, High linearity PA;High system nce;
2, Intelligent ALC technology;
3, Tag nrho duplex thiab kev sib cais siab ntawm uplink mus rau downlink;
4, Tsis siv neeg ua haujlwm yooj yim ua haujlwm;
5, Kev sib xyaw ua ke nrog kev ua tau zoo;
6, Kev saib xyuas hauv zos thiab chaw taws teeb (yeem) nrog lub tswb tsis siv neeg & tswj chaw taws teeb;
7, Weatherproof tsim rau tag nrho cov huab cua installation;
- Daim ntawv thov & scenarios
-
GSM 900 mhz xov tooj teeb liab daim ntawv thov
Txhawm rau nthuav cov teeb liab kev pab them nqi ntawm cov teeb liab qhov muag tsis pom qhov chaw teeb liab tsis muaj zog
los yog tsis muaj.
Sab nraum zoov: tshav dav hlau, Tourism Regions, Golf Course, Tunnels, Factories, Mining Districts, Zos thiab lwm yam.
Sab hauv: Chaw ntiav pw, Exhibition Centers, Basements, Khw
Malls, Chaw Ua Haujlwm, Ntim Ntau thiab lwm yam.
Nws yog feem ntau siv rau cov xwm txheej zoo li no:
Tus repeater tuaj yeem nrhiav qhov chaw teeb tsa uas tuaj yeem tau txais cov teeb liab BTS ntshiab ntawm qhov muaj zog txaus raws li Rx Qib hauv qhov chaw repeater yuav tsum ntau dua -70dBm;
Thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev sib cais ntawm kav hlau txais xov kom tsis txhob muaj tus kheej oscillation.
