I-iDEN/TETRA 800MHz +27dBm Off-air BDA (Bi-Directional Amplifier) iyisiginali ye-RF esetshenziselwa ukuthuthukisa ukuxhumana kwerediyo ezimeni lapho isignali yomsakazo.
Uhlelo lwe-Kingtone Repeaters luklanyelwe ukuxazulula izinkinga zesignali yeselula ebuthakathaka, eshibhe kakhulu kunokwengeza i-Base Station entsha (BTS).Ukusebenza okuyinhloko kohlelo lwe-RF Repeaters ukuthola isignali yamandla aphansi evela ku-BTS ngokusakazwa kwamafrikhwensi omsakazo bese idlulisela isignali ekhulisiwe ezindaweni lapho ukutholakala kwenethiwekhi kungenele.Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS ngendlela ehlukile.
Okuyinhloko Izici
1,I-PA ephezulu yomugqa;Ukuzuza kwesistimu ephezulu;
2, Intelligent ALC ubuchwepheshe;
3,I-duplex ephelele kanye nokuhlukaniswa okuphezulu kusuka ku-uplink kuya ku-downlink;
4, Ukusebenza okuzenzakalelayo ukusebenza okulula;
5,Isu elihlanganisiwe nokusebenza okuthembekile;
6, Ukuqapha kwendawo nokukude (kuyakhetheka) nge-alamu yephutha elizenzakalelayo &isilawuli kude;
7, Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
