China Kingtone amapereka Mtengo Wogwira Ntchito Pachitetezo Pagulu TETRA, iDEN 800 MHz Band Frequency 806-821/851-866 MHz Repeater BDA Bi-Directional Amplifier for Critical Communication.
Dongosolo la TETRA 800MHz +33dBm Off-air Bi-Directional Amplifier(BDA) lapangidwa kuti lithetse mavuto a siginecha yofooka, yomwe ndiyotsika mtengo kwambiri kuposa kuwonjezera Base Station (BTS) yatsopano.Ntchito yayikulu ya 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.
Chachikulu Mawonekedwe
◇ Mkulu mzere PA;Kupindula kwakukulu kwadongosolo;
◇ Ukadaulo wanzeru wa ALC;
◇ Full duplex ndi kudzipatula mkulu kuchokera uplink mpaka downlink;
◇ Makinawa Ogwiritsa ntchito bwino;
◇ Njira yophatikizika yokhala ndi magwiridwe antchito odalirika;
◇ Kuyang'anira kwanuko komanso patali (posankha) ndi ma alarm angozi & chiwongolero chakutali;
◇ Mapangidwe osagwirizana ndi nyengo pokhazikitsa nyengo zonse;
Ntchito Yodziwika:
Kumanga chitetezo cha anthu opanda zingwe network wideband iDEN Repeater 800MHz (806-821MHz / 851-866MHz ) BDA Repeater Amplifier
kukulitsa kufalikira kwa ma siginecha a madera akhungu omwe chizindikiro ndi chofooka kapena palibe.
