UninziVHFI-Bi-Directional Amplifiers ilungiselelwe iRadio Frequency eyilelwe ukuphatha isicelo esithile samaza.

-Kingtone JIMTOM®VHFI-Amplifaya-yamacala amabini(BDA) yenzelwe ukusombulula iingxaki zesiginali yeselula ebuthathaka, enexabiso eliphantsi kakhulu kunokongeza iSikhululo esitsha seSiseko (BTS).Umsebenzi ongundoqo we-RF VHF Bi-directional-Amplifier(BDA) kukufumana isignali yamandla aphantsi ukusuka kwi-BTS ngosasazo lwamaza kanomathotholo emva koko isasaze umqondiso owandisiweyo kwiindawo apho unxibelelwano lwenethiwekhi lunganelanga.Kwaye isiginali yeselula nayo ikhulisiwe kwaye idluliselwe kwi-BTS ngendlela echaseneyo.

Iimpawu eziphambili

◇ Iyahambelana ne-DMR, TETRA, 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 lokuzuza olulungelelanisiweyo lomsebenzisi, iUL neDL ezizimeleyo;

◇ Ulawulo lokuNgena oluzenzekelayo;

◇ Ujongo lwasekhaya kunye nolukude (ukhetho) nge-alam yempazamo ezenzekelayo & nolawulo olukude;

◇ IP67/NEMA4X uyilo lokumelana nemozulu yofakelo lwemozulu yonke;
