Uhf Xov tooj cua Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Selective Signal Repeater Booster system yog tsim los daws cov teeb meem ntawm cov teeb liab tsis muaj zog, uas yog pheej yig dua li ntxiv qhov chaw nres tsheb tshiab (BTS).Lub luag haujlwm tseem ceeb ntawm RF Repeaters system yog kom tau txais cov teeb liab hluav taws xob tsawg los ntawm BTS los ntawm kev xa xov tooj cua zaus thiab tom qab ntawd xa cov teeb liab amplified mus rau thaj chaw uas tsis muaj kev pab cuam network.Thiab lub teeb liab ntawm lub xov tooj ntawm tes kuj tau nthuav dav thiab xa mus rau BTS ntawm qhov kev coj ua.
Lub ntsiab nta
◇ Tau tshaj TETRA, TETRAPOL, P25 (Ph1 thiab Ph2)
◇ High linearity PA, High system nce, Intelligent ALC technology
◇ Tag nrho duplex thiab kev sib cais siab ntawm uplink mus rau downlink;
◇ Auto diagnostic, Tsis Siv Neeg Ua Haujlwm yooj yim ua haujlwm;
◇ Tus neeg siv tuaj yeem tswj tau nce, UL thiab DL ywj siab, ib qho channel;
◇ Kev saib xyuas hauv zos thiab chaw taws teeb (yeem) nrog lub tswb tsis siv neeg & tswj chaw taws teeb; SNMP raws tu qauv (yeem).
◇ IP67 / NEMA4X Huab cua tsis zoo tsim rau txhua qhov huab cua.
