Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Selective Signal Repeater Booster tsarin an tsara shi don magance matsalolin siginar wayar hannu mara ƙarfi, wanda ya fi arha fiye da ƙara sabon Tashar Base (BTS).Babban aikin tsarin RF Repeaters shine karɓar sigina mara ƙarfi daga BTS ta hanyar watsa mitar rediyo sannan watsa siginar ƙararrawa zuwa wuraren da keɓaɓɓen ɗaukar hoto na cibiyar sadarwa bai isa ba.Hakanan ana ƙara siginar wayar hannu kuma ana watsa shi zuwa BTS ta wata hanya dabam.
Babban Siffofin
◇ Mai jituwa tare da TETRA, TETRAPOL, P25 (Ph1 da Ph2)
◇ High linearity PA, Babban tsarin riba, fasaha ALC mai hankali
◇ Cikakken duplex da babban keɓewa daga sama zuwa ƙasa;
◇ Bincike ta atomatik, Aiki ta atomatik dacewa aiki;
◇ Mai amfani daidaitacce riba iko, UL da DL masu zaman kansu, ta kowane tashar;
◇ Kulawa na gida da na nesa (na zaɓi) tare da ƙararrawa kuskure ta atomatik & sarrafawa mai nisa; ka'idar SNMP (na zaɓi) .
◇ IP67/NEMA4X ƙirar yanayin yanayi don shigar da duk yanayin yanayi.
