Kingtone JIMTOM® Fiber Optic Repeaters system yakagadzirirwa kugadzirisa matambudziko eiyo isina simba nharembozha, iyo yakachipa zvakanyanya pane kuseta Base Station (BTS).Kushanda kukuru kweRF Repeaters system: Kune iyo yepasi link, masiginecha kubva kuBTS anopihwa kuMaster Unit (MU), iyo MU yobva yashandura RF siginecha kuita laser siginecha yobva yadyisa kune fiber kuendesa kuRemote Unit (RU).RU yobva yashandura siginecha yelaser kuita chiratidzo cheRF, uye shandisa Power Amplifier kukwidziridza kune yakakwirira simba kuIBS kana yekuvhara antenna.Kune iyo kumusoro link, Iri reverse process, masaini kubva kumushandisi nhare anopihwa kune MU's MS port.Via duplexer, chiratidzo chinokwidziridzwa neakadzika ruzha amplifier kuvandudza simba rechiratidzo.Ipapo masaini anopihwa kuRF fiber optical module yobva yashandurwa kuita masaini emalaser, ipapo siginecha yelaser inotumirwa kuMU, iyo laser siginecha kubva kuRU inoshandurwa kuita RF chiratidzo neRF optical transceiver.Ipapo masaini eRF anokwidziridzwa kune mamwe masaini esimba anopihwa kuBTS.
RF Repeater yakagadzirirwa kusimudzira nharembozha yekuvhara uye kuzadza mapofu.Kushanda kukuru kweanodzokorora kugashira yakaderera-simba chiratidzo kubva kuBase Station (BS) kuburikidza neredhiyo frequency (RF) kutapurirana neanopa antenna, gadzirisa, kusimudzira uye kuendesa chiratidzo kuMobile Station (MS) munzvimbo inotarirwa yekuvhara nebasa rayo. antenna.
