I hangaia te punaha Whakanui-a-Kingtone Bi-Directional Amplifier ki te whakaoti rapanga o te tohu waea ngoikore, he iti ake te utu atu i te taapiri i te Teihana Turanga (BTS) hou.Ko te UHF BDA he otinga tukurua i hangaia me te whakaaro ki nga kaiwhakautu tuatahi mo te haumarutanga.
Ko te mahi matua o te punaha RF Bi-Directional Amplifiers ko te whiwhi tohu iti-hiko mai i te BTS ma te tuku auau reo irirangi katahi ka tuku i te tohu whakakaha ki nga waahi kaore i te tika te kapi o te whatunga.Na ka whakanuia ano te tohu pūkoro ka tukuna ki te BTS ma te huarahi rereke.
Āhuatanga Matua:
1, PA raina teitei;Te whiwhinga punaha teitei;
2, Hangarau ALC Intelligent;
3, Hangarau AGC Intelligent;
4, Katoa te taarua me te wehe teitei mai i te hono whakarunga ki te hono whakararo;
5,Mahi Aunoa mahi watea;
6, Hangarau whakauru me te mahi pono;
7, Te aro turuki i te rohe me te mamao (he kowhiringa) me te whakaoho hapa aunoa & te mana mamao;
8, Hoahoa ahuru mo te whakaurunga o nga rangi katoa;
