I-Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Isitishi esiKhethekileyo seSiphawuli esiPhindayo inkqubo yenzelwe ukusombulula iingxaki zesiginali yeselula ebuthathaka, enexabiso eliphantsi kakhulu kunokongeza iSikhululo esitsha seSiseko (BTS).Owona msebenzi uphambili we-RF Repeaters system kukufumana umqondiso wamandla aphantsi osuka kwi-BTS ngosasazo lwamaza kanomathotholo emva koko usasaze umqondiso owandisiweyo kwiindawo apho unxibelelwano lwenethiwekhi lunganelanga.Kwaye isiginali yeselula nayo ikhulisiwe kwaye idluliselwe kwi-BTS ngendlela echaseneyo.
Iimpawu eziphambili
◇ Iyahambelana neTETRA, TETRAPOL, P25 (Ph1 kunye nePh2)
◇ Umgca ophezulu we-PA, inzuzo ephezulu yenkqubo, iteknoloji ye-ALC ehlakaniphile
◇ I-duplex epheleleyo kunye nokwahlukaniswa okuphezulu ukusuka kwi-uplink ukuya kwi-downlink;
◇ Uxilongo oluzenzekelayo, Ukusebenza okuzenzekelayo ukusebenza kakuhle;
◇ Ulawulo lwenzuzo elungelelanisiweyo yomsebenzisi, i-UL ne-DL ezimeleyo, ngetshaneli nganye;
◇ Ujongo lwasekhaya kunye nolukude (ukhetho) nge-alam yempazamo ezenzekelayo &ulawulo olukude;iprothokholi yeSNMP (ukhetho) .
◇ IP67/NEMA4X uyilo lokumelana nemozulu yofakelo lwemozulu yonke.
