Sistem Kingtone JIMTOM® Fiber Optic Repeater dirancang kanggo ngatasi masalah sinyal seluler sing ringkih, sing luwih murah tinimbang nyetel Base Station (BTS) anyar.Operasi utama sistem RF Repeater: Kanggo link mudhun, sinyal saka BTS diwenehake menyang Master Unit (MU), MU banjur ngowahi sinyal RF dadi sinyal laser banjur feed menyang serat kanggo ngirim menyang Remote Unit (RU).RU banjur ngowahi sinyal laser kanggo sinyal RF, lan nggunakake Power Amplifier kanggo amplify kanggo daya dhuwur kanggo IBS utawa antena jangkoan.Kanggo link munggah, Apa proses mbalikke, sinyal saka seluler pangguna dipakani kanggo port MS MU.Liwat duplexer, sinyal digedhekake dening amplifier swara sing kurang kanggo nambah kekuatan sinyal.Banjur sinyal kasebut dipakani menyang modul optik serat RF banjur diowahi dadi sinyal laser, banjur sinyal laser dikirim menyang MU, sinyal laser saka RU diowahi dadi sinyal RF dening transceiver optik RF.Banjur sinyal RF digedhekake dadi sinyal kekuatan sing luwih akeh sing diwenehake menyang BTS.
RF Repeater dirancang kanggo nambah jangkoan jaringan seluler lan ngisi titik wuta.Operasi utama repeater yaiku nampa sinyal kurang daya saka Base Station (BS) liwat transmisi frekuensi radio (RF) dening antena donor, ngolah, nggedhekake lan nerusake sinyal menyang Mobile Station (MS) ing area jangkoan target kanthi layanan kasebut. antena.
