I-Kingtone JIMTOM® Wireless Channel Selective Bi-direction Amplifier iyizixazululo ezingabizi kakhulu nezithembekile eziklanyelwe ukunweba nokuthuthukisa indawo ekhavayo ye-Tetra BTS.Ikakhulukazi lapho indawo yomsakazo iyinkimbinkimbi futhi ukuphazamiseka kuyindawo enamandla.Isiteshi esingenantambo esikhethiweBDAikhulisa futhi ikhethe abathwali abafunwa kuzo zombili izinkomba, i-uplink ne-downlink.Ngokusekelwe ku-FPGA yayo yokusebenza okuphezulu kwesiteshi esikhethiwe sokuhlunga kwedijithali, ukulandelana okuphezulu nama-PA asebenza kahle, uhlelo oluqinile lokusebenza nolokulungisa, i-BDA iyisixazululo esinamandla nesomnotho sokuthuthukisa indawo ekhavayo ye-BTS.Izimo ezijwayelekile zokusetshenziswa zale BDA: amathaneli, izakhiwo, imigwaqo engaphansi komhlaba, nezimo zangaphandle njengezinkundla zemidlalo, izindawo zasemaphandleni nezindawo zasemadolobheni eziminyene.
Ngohlamvu oluphezulu lokukhetha, I-Channel Selective Repeater inikeza ukucindezelwa okuphakeme ngaphandle kwesiteshi ukugwema ukuphazamisa iziteshi eziseduze.
Ingasetshenziswa endaweni yasemadolobheni ye-RF lapho ihlaselwe khona ukuphazamiseka okubangelwa amasignali anzima abanikeli.
I-Channel Selective Repeater nayo iyisixazululo esikahle endaweni yasemaphandleni.
I-Channel Selective Repeater ifanele inethiwekhi ene-base-band hopping noma i-synthesizer egxumayo ngaphansi kwamashaneli ayi-16.
410-415MHz ye-Uplink (imisakazo kuya kwabaphindayo) kanye no-420-425MHz ku-Downlink (abaphindayo kumarediyo)
Umkhiqizi we-Tetra Repeater-I-Kingtone ikhiqiza i-Tetra repeater efanelekayo futhi isekela i-OEM nemiklamo eyenziwe ngokwezifiso.Ngaphambi koku-oda, sicela usitshele i-TX ne-RX.
