I-Tetra 380MHz iBand eKhethekileyo 380-385 MHz 390-395 MHZ Indlela ezimbini kwirediyo ye-UHF yangaphandle yeSikhumbuzi seSiphawuli esine-RJ45
I-frequency band 380-385 MHz (uplink) / 390-395 MHz (downlink) yenzelwe ukusombulula iingxaki zesignali yeselula ebuthathaka, engabizi kakhulu kunokongeza iSikhululo seSiseko esitsha (BTS).Ukusebenza okungundoqo kwe-RF Bi-Directional Amplifiers inkqubo 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.
Amagqabantshintshi eMveliso:
● Ngoyilo lwemodyuli, kulula ukuyigcina
● Ukubeka iliso kwi-software ekude (i-serial port), kulula kuyoulondolozo nolawulo.
● IP55 ingangenwa luthuli & ingangeni manzi, ineemfuno eziphantsi kwindawo yofakelo;
● Nge-amplifier yamandla ekumgangatho ophezulu kunye ne-high-rejection duplexer, ekwazi ukwala ukudibanisa kunye neempawu ezikhohlisayo.
