I-iDEN/TETRA 800MHz +27dBm Off-air BDA (i-Bi-Directional Amplifier) sisixhobo se-RF esikhuthazayo esisetyenziselwa ukuphucula unxibelelwano lwerediyo kwiimeko apho umqondiso werediyo.
Inkqubo ye-Kingtone Repeaters yenzelwe ukusombulula iingxaki zesignali yeselula ebuthathaka, enexabiso eliphantsi kunokongeza iSikhululo esitsha seSiseko (BTS).Umsebenzi ongundoqo we-RF Repeaters system kukufumana umqondiso wamandla aphantsi ovela kwi-BTS ngosasazo lwamaza kanomathotholo emva koko usasaze umqondiso owandisiweyo kwiindawo apho unxibelelwano lwenethiwekhi lunganelanga.Kwaye isignali yeselula nayo ikhulisiwe kwaye idluliselwe kwi-BTS ngendlela echaseneyo.
Engundoqo Iimbonakalo
1,Umgca ophezulu we-PA;Ukuzuza kwenkqubo ephezulu;
2, itekhnoloji ye-ALC ekrelekrele;
3,I-duplex epheleleyo kunye nokwahlukaniswa okuphezulu ukusuka kwi-uplink ukuya kwi-downlink;
4, Ukusebenza okuzenzekelayo ukusebenza kakuhle;
5, ubuchule obudityanisiweyo kunye nokusebenza okuthembekileyo;
6, Ukubekwa esweni kwasekhaya kunye nokude (ukhetho) nge-alarm yempazamo ezenzekelayo & nolawulo olukude;
7, uyilo lokumelana nemozulu yofakelo lwemozulu yonke;
