iDEN/TETRA 800MHz +27dBm Off-air BDA (Bi-Directional Amplifier) ndi chowonjezera cha RF chomwe chimagwiritsidwa ntchito popititsa patsogolo kuyankhulirana pawailesi pomwe mawayilesi amawululira.
Dongosolo la Kingtone Repeaters lapangidwa kuti lithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kuwonjezera Base Station yatsopano (BTS).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
1,High linearity PA;Kupindula kwakukulu kwadongosolo;
2,ukadaulo wanzeru wa ALC;
3,Duplex wathunthu komanso kudzipatula kwakukulu kuchokera ku uplink kupita ku downlink;
4, Automatic Operation yabwino ntchito;
5, Integrated njira ndi ntchito odalirika;
6, Kuyang'anira kwanuko ndi kutali (ngati mukufuna) ndi alamu yangozi yokha & chiwongolero chakutali;
7, kamangidwe kanyengo kosunga nyengo zonse;
