Tuam Tshoj Kingtone muab Tus Nqi Zoo Tshaj Plaws Hauv Pej Xeem Kev Nyab Xeeb TETRA, iDEN 800 MHz Band Zaus 806-821 / 851-866 MHz Repeater BDA Bi-Directional Amplifier rau Kev Sib Txuas Lus Tseem Ceeb.
TETRA 800MHz + 33dBm Off-air Bi-Directional Amplifier (BDA) 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 them nqi 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;
◇ 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;
Daim Ntawv Thov:
Hauv kev tsim pej xeem kev nyab xeeb wireless networks wideband iDEN Repeater 800MHz (806-821MHz / 851-866MHz) BDA Repeater Amplifier
kom nthuav dav cov teeb liab kev pab cuam ntawm cov teeb liab qhov muag tsis pom qhov teeb liab tsis muaj zog lossis tsis muaj.
