IningiI-VHFAma-Bi-Directional Amplifiers ama-Radio Frequency enziwe ngokwezifiso aklanyelwe ukuphatha isicelo esithile sefrikhwensi.

- Kingtone JIMTOM®I-VHFIsikhulisi se-Bi-directional-AmplifayaBDA) yakhelwe ukuxazulula izinkinga zesignali yeselula ebuthakathaka, eshibhe kakhulu kunokwengeza i-Base Station entsha (BTS).Ukusebenza okuyinhloko kwe-RF VHF Bi-directional-Amplifier(BDA) ukuthola isignali yamandla aphansi evela ku-BTS ngokudluliswa kwefrikhwensi yomsakazo bese idlulisela isignali ekhulisiwe ezindaweni lapho ukutholakala kwenethiwekhi kungenele.Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS ngendlela ehlukile.

Izici Eziyinhloko

◇ Ihambisana ne-DMR, TETRA, TETRAPOL, P25 (Ph1 ne-Ph2)

◇ I-PA ephezulu yomugqa, inzuzo ephezulu yesistimu, ubuchwepheshe be-Intelligent ALC

◇ I-duplex egcwele kanye nokuhlukaniswa okuphezulu kusuka ku-uplink kuya ku-downlink;

◇ Auto diagnostic, Automatic Operation operation elula;

◇ Ukulawulwa kwenzuzo okungalungiseka komsebenzisi, i-UL ne-DL ezimele;

◇ Ukulawula Ukuzuza Okuzenzakalelayo;

◇ Ukuqapha kwendawo nokukude (ongakukhetha) nge-alamu yephutha elizenzakalelayo &isilawuli kude;

◇ IP67/NEMA4X Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
