Sisitemu ya Kingtone Bi-Directional Amplifiers yateguwe kugirango ikemure ibibazo byikimenyetso kigendanwa kidakomeye, gihendutse cyane kuruta kongeramo Sitasiyo nshya (BTS).Igikorwa nyamukuru cya sisitemu ya Bi-Directional Amplifiers ni ukwakira signal nkeya - ingufu ziva muri BTS hakoreshejwe radiyo yumurongo wa radiyo hanyuma ikohereza ibimenyetso byongerewe imbaraga mubice bidahagije.Kandi ibimenyetso bigendanwa nabyo byongerewe kandi byoherezwa muri BTS binyuze muburyo bunyuranye.
Line Umurongo muremure PA;Sisitemu yo hejuru gain
Technology Ubwenge bwa ALC bwubwenge ；
Technology Ubwenge bwa AGC bwikoranabuhanga ；
Up Duplex yuzuye hamwe no kwigunga cyane kuva hejuru kugeza kumanuka ；
Operation Gukora mu buryo bwikora imikorere yoroshye ；
Tekinike ihuriweho hamwe nibikorwa byizewe;
Monitoring Gukurikiranira hafi no kure (bidashoboka) hamwe no gutabaza byikora & kugenzura kure;
Design Igishushanyo mbonera cyogushiraho ibihe byose;
