Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Selective Signal Repeater Booster 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 chiratidzo chakasimudzirwa kunzvimbo dzisina kuvharwa netiweki.Uye iyo nharembozha inokwidziridzwa uye kuendeswa kuBTS kuburikidza neyakapesana.
Main Features
◇ Inoenderana neTETRA, TETRAPOL, P25 (Ph1 nePh2)
◇ Yakakwira mutsara PA, Yakakwira system kuwana, Intelligent ALC tekinoroji
◇ Yakazara duplex uye yakakwirira kuzviparadzanisa kubva kumusoro kumusoro kuenda kudownlink;
◇ Auto diagnostic, otomatiki Kushanda nyore kushanda;
◇ Mushandisi anogadziriswa kuwana kudzora, UL uye DL yakazvimirira, pachiteshi;
◇ Yenzvimbo uye kure yekutarisa (isarudzo) ine otomatiki kukanganisa aramu & kudzora kure;SNMP protocol (sarudzo) .
◇ IP67/NEMA4X Weatherproof dhizaini yekumisikidza kwese-mamiriro ekunze.
