Iyo Frequency Shift Repeater (FSR) yakagadzirirwa kugadzirisa matambudziko eiyo isina kusimba nharembozha, iyo inogona kuwedzera kuvharika kupfuura RF inodzokorora uye kuderedza mari yekudyara kunzvimbo dzisina fiber optic tambo.
Iyo yese FSR system ine zvikamu zviviri: Donor Unit uye Remote Unit. Ivo vanoendesa pachena uye nekukudza iyo isina waya siginecha pakati peBTS (Base Transceiver Station) uye nharembozha kuburikidza neRF wave pane akasiyana frequency kubva kuBTS.
Iyo Donor unit inogamuchira iyo BTS chiratidzo kuburikidza yakananga coupler yakavharirwa kuBTS (kana kuburikidza nemhepo yakavhurika RF kutapurirana kuburikidza neDonor Antenna), yobva yaishandura kubva pakushanda frequency kuenda kune frequency yekubatanidza, uye yoendesa chiratidzo chakasimudzirwa kuRemote Unit kuburikidza. iyo Link Antennas. Iyo Remote Unit ichadzosera chiratidzo kune iyo frequency yekushanda uye inopa chiratidzo kune iyo nzvimbo iyo network yekuvhara haina kukwana. Uye iyo nharembozha inokwidziridzwa uye inotumirwa kuBTS kuburikidza neyakapesana.

Features:
1,Best solution yekubvisa kupindirana nekuda kwekugovana frequency yakafanana;
2, Hapana zvakaomesesa zvekuzviparadzanisa nevamwe pakugadzwa kweantenna;
3, Zviri nyore kusarudza yekuisa saiti;
4, Iyo Remote Unit inogona kuiswa kunze kweiyo BTS yekuvhara;
5, RS-232 ports inopa zvinongedzo kubhuku rekutarisa remunharaunda uye kune yakavakirwa-mukati isina waya modem kutaurirana neNMS (Network Management System) iyo inogona kutarisa kure kure mashandiro eanodzokorora uye kudhawunirodha maparamendi ekushanda kune anodzokorora.
6, Aluminium-alloy casing ine yakakwirira kuramba guruva, mvura uye corroding;
