Tetra 400 MHz Two Way Radio UHF Channel Selective RF BDA Signal Repeater Bi-Directional Amplifier ndi chowonjezera cha RF chomwe chimagwiritsidwa ntchito kupititsa patsogolo mawayilesi amtundu wa wailesi.
BDA (Bi-Directional Amplifier) imagwiritsidwa ntchito popereka kulumikizana kwapawiri pakati pa ma wayilesi ndi masiteshoni oyambira kuti agwirizane ndi malo amtundu uliwonse.Itha kugwiritsidwa ntchito panja kuti iwonjezere kufalikira kwa malo oyambira, kupanga zolumikizirana zizipezeka m'malo opanda ma siginecha ofooka, omwe amatengedwa kwambiri ngati ma tunnel, misewu, njanji, madera akunja, malo okhala anthu ambiri, ndi zina zambiri.
Main Features
◇ Yogwirizana ndi TETRA, TETRAPOL, P25 (Ph1 ndi Ph2)
◇ High linearity PA, High dongosolo phindu, Intelligent ALC luso
◇ Full duplex ndi kudzipatula mkulu kuchokera uplink mpaka downlink;
◇ Auto diagnostic, Automatic Opaleshoni yabwino ntchito;
◇ Kuwongolera kosinthika kwa ogwiritsa ntchito, UL ndi DL palokha, panjira iliyonse;
◇ Kuyang'anira kwanuko komanso patali (posankha) ndi alamu yangozi yokha & chiwongolero chakutali; protocol ya SNMP (posankha) .
◇ Mapangidwe a IP67/NEMA4X osagwirizana ndi nyengo pokhazikitsa nyengo yonse.
