Tetra 400 MHz Two Way Radio UHF Channel Selective RF BDA Signal Repeater Bi-Directional Amplifier iRF chiratidzo booster inoshandiswa kuvandudza kutaurirana neredhiyo mumamiriro ezvinhu apo chiratidzo cheredhiyo.
BDA (Bi-Directional Amplifier) inoshandiswa kupa bidirectional kutaurirana pakati peredhiyo terminals uye base chiteshi kuitira kuti ikwane mune chero mhando yenzvimbo.Inogona kushandiswa kunze kuwedzera nzvimbo yekuvhara ye base station, ichiita kuti masevhisi ekutaurirana awanikwe munzvimbo dzisina kana masaini asina simba, ayo anogamuchirwa zvakanyanya kumatanho, migwagwa, njanji, nzvimbo dzekunze, nzvimbo dzekugara dzakatsvikinyidzana, nezvimwe.
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.
