Kingtone Bi-Directional Amplifier system ua mamanuina e foia ai faafitauli o le vaivai telefoni feaveai, lea e sili atu le taugofie nai lo le faaopoopoina o se Base Station fou (BTS).O le UHF BDA o se fofo toe fai lea na mamanuina ma le saogalemu o tagata lautele e tali atu muamua i le mafaufau.
O le fa'agaioiga autu o le RF Bi-Directional Amplifiers system o le mauaina lea o le fa'ailo maualalo mai le BTS e ala i le leitio fa'asalalau ona fa'asalalau atu lea o le fa'ailoga fa'ateleina i nofoaga o lo'o le atoatoa ai feso'otaiga.Ma o le telefoni feaveaʻi e faʻateleina foi ma tuʻuina atu i le BTS e ala i le isi itu.
Vaega Autu:
1, laina maualuga PA;maualuga faiga maua;
2, Tekinolosi ALC atamai;
3, Tekinolosi AGC atamai;
4, Full duplex ma maualuga vavaeeseina mai uplink i lalo;
5,Otometi Faagaioiga faagaoioiga faigofie;
6, auala tu'ufa'atasi ma fa'atinoga fa'atuatuaina;
7, Mata'ituina fa'apitonu'u ma mamao (filifiliga) fa'atasi ai ma fa'ailo fa'aletonu fa'afuase'i & pulea mamao;
8, Fuafuaga le tau mo le faʻapipiʻiina o tau uma;
