Dongosolo la Kingtone Bi-Directional Amplifiers lapangidwa kuti lithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kuwonjezera Base Station (BTS).Kugwira ntchito kwakukulu kwa RF Bi-Directional Amplifiers 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.
◇ Mkulu mzere PA;Kupindula kwakukulu kwadongosolo;
◇ Ukadaulo wanzeru wa ALC;
◇ Ukadaulo wanzeru wa AGC;
◇ 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;
