Eto Awọn Amplifiers Bi-itọnisọna Kingtone jẹ apẹrẹ lati yanju awọn iṣoro ti ifihan agbara alagbeka alailagbara, eyiti o din owo pupọ ju fifi Ibusọ Base tuntun kan (BTS) kun.UHF BDA jẹ ojutu atunwi ti a ṣe apẹrẹ pẹlu aabo gbogbo eniyan ni awọn oludahun akọkọ ni lokan.
Iṣe akọkọ ti RF Bi-Directional Amplifiers eto ni lati gba ifihan agbara kekere lati BTS nipasẹ gbigbe igbohunsafẹfẹ redio ati lẹhinna tan kaakiri ifihan agbara si awọn agbegbe nibiti agbegbe nẹtiwọọki ko pe.Ati pe ifihan agbara alagbeka tun pọ si ati gbigbe si BTS nipasẹ itọsọna idakeji.
