Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Selective Signal Repeater Booster system idapangidwa kuti ithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kuwonjezera Base Station (BTS).Kugwira ntchito kwakukulu kwa RF Repeaters system ndikulandila siginecha yamphamvu yotsika kuchokera ku BTS kudzera pawayilesi yawayilesi ndikutumiza siginecha yokwezeka kumadera omwe kulumikizidwa kwa netiweki sikukwanira.Ndipo siginecha yam'manja imakulitsidwanso ndikutumizidwa ku BTS kudzera mbali ina.
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.
