Kingtone JIMTOM® Wireless Channel Selective Bi-direction Amplifier ndi njira zotsika mtengo komanso zodalirika zopangidwira kukulitsa ndikuwongolera gawo la Tetra BTS.Makamaka pamene malo wailesi ndi zovuta ndi kusokoneza ndi amphamvu dera.Kusankha njira yopanda zingweBDAimakulitsa ndikusankha zonyamulira zomwe zimafunidwa mbali zonse ziwiri, uplink ndi downlink.Ndi FPGA yake yochokera kumayendedwe apamwamba osankha digito, mizere yayikulu komanso ma PA ogwira ntchito, njira yolimba yogwirira ntchito ndi kukonza, BDA ndi yankho lamphamvu komanso lachuma kupititsa patsogolo gawo la BTS.Zochitika zodziwika bwino za BDA iyi: ngalande, nyumba, njanji zapansi panthaka, ndi zochitika zakunja monga masitediyamu, madera akumidzi ndi madera akumidzi.
Ndi mawonekedwe apamwamba osankhidwa, Channel Selective Repeater imapereka kuponderezedwa kwapamwamba kwa kunja kwa njira kuti asasokoneze njira zoyandikana nazo.
Itha kugwiritsidwa ntchito kumadera akumatauni a RF komwe amavutika ndi kusokonezedwa chifukwa cha ma siginecha ovuta opereka.
Channel Selective Repeater ndi yankho labwino kumadera akumidzi.
Channel Selective Repeater ndiyoyenera netiweki yokhala ndi bande-band hopping kapena synthesizer yodumphadumpha zosakwana 16.
410-415MHz ya Uplink (mawayilesi mpaka obwereza) ndi 420-425MHz ya Downlink (obwereza ku mawailesi)
Wopanga Tetra Repeater-Kingtone kubala oyenerera Tetra repeater ndi thandizo OEM ndi mapangidwe makonda.Musanayitanitsa, chonde tiuzeni TX ndi RX.
