Kingtone system yog tsim los daws cov teeb meem ntawm lub teeb liab tsis muaj zog ntawm lub xov tooj ntawm tes, 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.
Main nta:
◇ Siab linearity PA;High system nce;
◇ Intelligent ALC technology;
◇ Tag nrho duplex thiab kev sib cais siab ntawm uplink mus rau downlink;
◇ Tsis siv neeg ua haujlwm yooj yim ua haujlwm;
◇ Cov txheej txheem sib xyaw nrog kev ua tau zoo;
◇ Bandwidth tuaj yeem teeb tsa los ntawm 5-25MHz hauv kev ua haujlwm band.
◇ Kev saib xyuas hauv zos thiab chaw taws teeb (yeem) nrog lub tswb tsis siv neeg & tswj chaw taws teeb;
◇ Weatherproof tsim rau tag nrho cov huab cua installation;
