China Kingtone nawakake biaya Safety Public Tetra efektif, iDEN 800 MHz Band Frequency 806-821 / 851-866 MHz Repeater BDA Bi-Directional Amplifier kanggo Komunikasi Kritis.
Sistem TETRA 800MHz +33dBm Off-air Bi-Directional Amplifier( BDA) dirancang kanggo ngatasi masalah sinyal seluler sing ringkih, sing luwih murah tinimbang nambahake 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.
Utama Fitur
◇ PA linearitas dhuwur;Keuntungan sistem dhuwur
◇ Teknologi ALC cerdas;
◇ Full duplex lan isolasi dhuwur saka uplink menyang downlink;
◇ Operasi otomatis operasi trep;
◇ Teknik terpadu kanthi kinerja sing dipercaya;
◇ Pemantauan lokal lan remot (opsional) kanthi weker kesalahan otomatis & remot kontrol;
◇ Desain tahan cuaca kanggo instalasi kabeh cuaca;
Aplikasi tipikal:
Jaringan nirkabel keamanan umum ing gedung broadband iDEN Repeater 800MHz (806-821MHz / 851-866MHz) BDA Repeater Amplifier
kanggo nggedhekake jangkoan sinyal ing wilayah wuta sinyal sing sinyal banget utawa ora kasedhiya.
