I-Tetra 400 MHz Two Way Radio UHF Channel Selective RF BDA Signal Repeater Bi-Directional Amplifier iyi-booster yesignali ye-RF esetshenziselwa ukuthuthukisa ukuxhumana kwerediyo ezimeni lapho isignali yomsakazo.
I-BDA (i-Bi-Directional Amplifier) isetshenziselwa ukuhlinzeka ngokuxhumana okukabili phakathi kwamatheminali omsakazo kanye nesiteshi esiyisisekelo ukuze kungene kunoma yiluphi uhlobo lwezindawo.Ingasetshenziswa ngaphandle ukuze kunwetshwe uhla lokukhava lwesiteshi esiyisisekelo, ukwenza izinsiza zokuxhumana zitholakale ezindaweni ezingenawo amasiginali abuthaka, amukelwa kabanzi kumathaneli, imigwaqo, izitimela, izindawo ezingaphandle, izindawo zokuhlala eziminyene, njll.
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.
