Dongosolo la Kingtone Fiber Optic Repeaters lapangidwa kuti lithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kukhazikitsa Base Station (BTS).
-
-Kugwiritsa ntchito kwakukulu kwa RF Repeaters system:
Pa ulalo wapansi, ma sign ochokera ku BTS amaperekedwa ku Master Unit(MU), MU kenako amasintha siginecha ya RF kukhala siginecha ya laser kenako amadyetsa ku fiber kuti atumize ku Remote Unit(RU).RU ndiye sinthani chizindikiro cha laser kukhala chizindikiro cha RF, ndikugwiritsa ntchito Power Amplifier kukulitsa mphamvu yayikulu kukhala IBS kapena mlongoti wophimba.
Kwa uplink, Ndi njira yosinthira, ma siginecha ochokera kwa ogwiritsa ntchito amaperekedwa ku doko la MU la MS.Kudzera pa duplexer, siginecha imakulitsidwa ndi amplifier yaphokoso yotsika kuti ipititse patsogolo mphamvu yazizindikiro.Kenako ma sign amadyetsedwa ku RF fiber optical module kenako amasinthidwa kukhala ma laser, ndiye chizindikiro cha laser chimatumizidwa ku MU, chizindikiro cha laser chochokera ku RU chimasinthidwa kukhala chizindikiro cha RF ndi RF Optical transceiver.Kenako ma siginecha a RF amakulitsidwa kuzizindikiro zamphamvu zoperekedwa ku BTS.
- Nkhani yayikulu
- Main Features◇ 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 & zochitika
- MapulogalamuKukulitsa kufalikira kwa ma siginecha amtundu wakhungu wodzaza pomwe chizindikiro ndi chofooka
kapena osapezeka.
