iDEN/TETRA 800MHz +27dBm Off-air BDA (Bi–Directional Amplifier) ose fa'aola fa'alilolilo RF fa'aaogaina e fa'aleleia ai feso'ota'iga leitio i tulaga e fa'ailo ai le leitio.
O le Kingtone Repeaters system ua mamanuina e foia ai faafitauli o le vaivai telefoni feaveaʻi, lea e sili atu le taugofie nai lo le faʻaopoopoina o se Base Station fou (BTS).O le fa'agaioiga autu o le RF Repeaters system o le maua lea o le fa'ailo maualalo mai le BTS e ala i le alaleo alaleo fa'asalalau ma fa'asalalau atu le fa'ailoga fa'ateleina i vaega e le o atoatoa le feso'ota'iga.Ma o le telefoni feaveaʻi e faʻateleina foi ma tuʻuina atu i le BTS e ala i le isi itu.
Autu Vaega
1laina maualuga PA;maualuga faiga fa'aogaina;
2, atamai ALC tekinolosi;
3Full duplex ma maualuga le vavae ese mai luga i lalo i lalo;
4, Fa'agaoioiga otometi fa'agaioiga faigofie;
5, auala tu'ufa'atasi ma fa'atinoga fa'atuatuaina;
6, Mata'ituina fa'apitonu'u ma mamao (filifiliga) fa'atasi ai ma fa'ailo fa'aletonu fa'afuase'i & pulea mamao;
7, Fuafuaga e le tau mo le faʻapipiʻiina o tau uma;
