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 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'ailo fa'ateleina i nofoaga e le o atoatoa ai feso'otaiga.Ma o le telefoni feaveaʻi e faʻateleina foi ma tuʻuina atu i le BTS e ala i le isi itu.
◇ laina maualuga PA;maualuga faiga fa'aogaina;
