I-Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Selective Signal Repeater Booster uhlelo iklanyelwe ukuxazulula izinkinga zesignali yeselula ebuthaka, eshibhe kakhulu kunokwengeza Isiteshi Sesisekelo esisha (i-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.
Izici Eziyinhloko
◇ Ihambisana ne-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, isiteshi ngasinye;
◇ Ukuqapha kwasendaweni nokukude (ongakukhetha) nge-alamu yephutha elizenzakalelayo &isilawuli kude;iphrothokholi ye-SNMP (kuyakhetheka) .
◇ IP67/NEMA4X Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke.
