Kingtone Repeaters system yakagadzirirwa kugadzirisa matambudziko eiyo isina simba nharembozha, iyo yakachipa zvakanyanya pane kuwedzera Base Station (BTS).Kushanda kukuru kweRF Repeaters system ndeyekugamuchira yakaderera-simba chiratidzo kubva kuBTS kuburikidza neredhiyo frequency kutapurirana uye wobva waendesa iyo yakakwidziridzwa chiratidzo kunzvimbo dzisina kuvharwa netiweki.Uye iyo nharembozha inokwidziridzwa uye kuendeswa kuBTS kuburikidza neyakapesana.
Kingtone Fiber Optic RF Repeater mhinduro yakavimbika yekuwedzera nekuvandudza nzvimbo yekuvhara TETRA 800MHz network.
- Main Feature
- Main Features Repeater:
High linearity PA;High system kuwana;
Intelligent ALC tekinoroji;
Yakazara duplex uye yakakwirira yekuzviparadzanisa nevamwe kubva kuuplink kuenda kudownlink;
Automatic Operation yakanakira kushanda;
Integrated tekinoroji nekuita kwakavimbika;
Yemunharaunda uye kure yekutarisa (inosarudza) ine otomatiki kukanganisa alarm & kure kudzora;
Weatherproof dhizaini yekuisa-mamiriro ekunze ese;
- Application&scenarios

Tetra 800 inodzokorora Zvikumbiro
Kuwedzera kuvharwa kwechiratidzo chekuzadza chiratidzo bofu nzvimbo iyo chiratidzo chisina simba
kana kusavapo.
Kunze: Nhandare, Nharaunda dzeKushanya, Makosi eGorofu, Tunnels, Mafekitori, Dunhu reMigodhi, Misha nezvimwe.
Indoor: Hotels, Exhibition Centers, Basement, Shopping
Mall, Mahofisi, Packing Lots etc.
Iyo inonyanya kushanda kune yakadaro kesi:
Iyo inodzokorora inogona kuwana nzvimbo yekuisa iyo inogona kugamuchira yakachena BTS chiratidzo pane yakasimba zvakakwana nhanho sezvo iyo Rx Level mune inodzokorora saiti inofanirwa kupfuura -70dBm;
Uye inogona kusangana nezvinodiwa zvekuzviparadzanisa neantenna kudzivirira wega-oscillation.
