iDEN/TETRA 800MHz +27dBm Off-air BDA (Bi-Directional Amplifier) iRF chiratidzo chinosimudzira chinoshandiswa kuvandudza kutaurirana neredhiyo mumamiriro ezvinhu apo chiratidzo cheredhiyo.
Kingtone Repeaters system yakagadzirirwa kugadzirisa matambudziko eiyo isina simba nharembozha, iyo yakachipa zvakanyanya pane kuwedzera Base Station (BTS).Kunyanya kushanda kweRF Repeaters system kugashira yakaderera-simba siginecha kubva kuBTS kuburikidza neredhiyo frequency transmission uye wobva waendesa chiratidzo chakasimudzirwa kunzvimbo dzisina kuvharwa netiweki.Uye iyo nharembozha inokwidziridzwa uye kuendeswa kuBTS kuburikidza neyakapesana.
Main Features
1,High linearity PA;High system kuwana;
2, Intelligent ALC tekinoroji;
3,Yakazara duplex uye yakakwirira yekuzviparadzanisa nevamwe kubva kuuplink kuenda kudownlink;
4, otomatiki Operation nyore kushanda;
5, Yakabatanidzwa nzira ine yakavimbika kuita;
6, Yemunharaunda uye kure yekutarisa (inosarudza) ine otomatiki kukanganisa alarm & kure kudzora;
7, Weatherproof dhizaini yekumisikidza kwese-mamiriro ekunze;
