Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Sistem Tetra UHF Channel Selective Signal Repeater Booster dirancang kanggo ngatasi masalah sinyal seluler sing ringkih, sing luwih murah tinimbang nambah Base Station (BTS) anyar.Operasi utama sistem RF Repeater yaiku nampa sinyal kurang daya saka BTS liwat transmisi frekuensi radio lan banjur ngirim sinyal sing digedhekake menyang wilayah sing jangkoan jaringan ora cukup.Lan sinyal seluler uga digedhekake lan dikirim menyang BTS liwat arah sing ngelawan.
Fitur Utama
◇ Kompatibel karo TETRA, TETRAPOL, P25 (Ph1 lan Ph2)
◇ PA linearitas dhuwur, gain sistem dhuwur, teknologi ALC Cerdas
◇ Full duplex lan isolasi dhuwur saka uplink menyang downlink;
◇ Diagnostik otomatis, Operasi Otomatis sing trep;
◇ Kontrol gain luwes pangguna, UL lan DL independen, saben saluran;
◇ Pemantauan lokal lan remot (opsional) kanthi weker kesalahan otomatis & remot kontrol; Protokol SNMP (opsional).
◇ IP67/NEMA4X desain Weatherproof kanggo kabeh-weather instalasi.
