Kingtone JIMTOM® Wireless Channel Selective Bi-direction Amplifier yog cov txiaj ntsig zoo thiab txhim khu kev qha tsim los txuas ntxiv thiab txhim kho thaj tsam ntawm Tetra BTS.Tshwj xeeb tshaj yog rau qhov chaw xov tooj cua ib puag ncig nyuaj thiab cuam tshuam yog thaj chaw muaj zog.Lub wireless channel xaivBDAamplifies thiab xaiv cov neeg nqa khoom xav tau nyob rau hauv ob qho tib si cov lus qhia, uplink thiab downlink.Nrog nws cov FPGA raws li kev ua tau zoo channel xaiv cov lim dej, siab linearity thiab PAs tau zoo, kev ua haujlwm zoo thiab kev saib xyuas, BDA yog ib qho kev daws teeb meem zoo thiab kev lag luam los txhim kho thaj chaw BTS.Cov xwm txheej ntawm daim ntawv thov ntawm BDA no: tunnels, vaj tse, subways, thiab cov xwm txheej sab nraum zoov xws li chaw ntau pob, thaj chaw nyob deb nroog thiab cov nroog loj.
Nrog tus cwj pwm xaiv siab, Channel Selective Repeater muab kev tawm tsam zoo tshaj plaws kom tsis txhob cuam tshuam nrog cov channel uas nyob ib sab.
Nws tuaj yeem siv rau hauv nroog RF ib puag ncig uas raug kev cuam tshuam los ntawm kev cuam tshuam ntawm tus neeg pub dawb.
Channel Selective Repeater kuj yog ib qho kev daws teeb meem zoo tshaj plaws rau thaj chaw nyob deb nroog.
Channel Selective Repeater yog tsim rau lub network nrog lub hauv paus-band hopping lossis synthesizer hopping tsawg dua 16 raws.
410-415MHz rau Uplink (xov tooj cua rau repeaters) thiab 420-425MHz rau Downlink (repeaters rau xov tooj cua)
Tetra Repeater Chaw tsim tshuaj paus-Kingtone tsim tsim nyog Tetra repeater thiab txhawb OEM thiab customized tsim.Ua ntej xaj, thov qhia peb TX thiab RX .
