Kingtone 20W Tetra800MHz Two Way Radio UHF Band SelectiveSignal RepeaterBi-Directional Amplifier system yakagadzirirwa kugadzirisa matambudziko eiyo isina kusimba nharembozha, iyo yakachipa zvakanyanya pane kuwedzera Base Station nyowani (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.
Mainfeature
- Zvikamu Zvikuru zveTETRA 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;

TETRA800Mhz 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.
