Ma Frequency Shift Bwerezani (FSR) yapangidwa kuti ithetse mavuto amtundu wa mafoni ofooka, omwe amatha kukulitsa kufotokozera kuposa kubwereza kwa RF ndikuchepetsa ndalama kumadera omwe chingwe cha fiber optic sichipezeka.
Dongosolo lonse la FSR limakhala ndi magawo awiri: Donor Unit ndi Remote Unit. Amafalitsa ndi kukulitsa chizindikiritso chopanda zingwe pakati pa BTS (Base Transceiver Station) ndi ma foni kudzera pa RF wave pafupipafupi kuchokera ku BTS.
Gawo la Donor limalandira chizindikiro cha BTS kudzera pa cholumikizira chachindunji chotsekedwa ku BTS (kapena kudzera pa air air RF kudzera pa Donor Antenna), kenako imasintha kuchokera pafupipafupi mpaka kulumikizidwe kwa ulalo, ndikusamutsa chizindikirocho kupita ku Remote Unit kudzera the Antennas Link. Gawo Lakutali lisinthanso chizindikirocho kuti chizigwira ntchito pafupipafupi ndikupereka chisonyezo kumadera omwe kulumikizidwa kwa netiweki sikokwanira. Ndipo siginecha yam'manja imakwezedwa ndikutumizidwa ku BTS kudzera mbali ina.

Zofunika Kwambiri:
1, Njira yabwino kwambiri yothetsera kusokonezana chifukwa chogawana pafupipafupi;
2, Palibe chofunikira chodzipatula chokha pakukhazikitsa ma antenna;
3, Yosavuta kusankha kukhazikitsa malo;
4, The Remote Unit ikhoza kukhazikitsidwa kunja kwa kufalikira kwa BTS;
5, ma RS-232 amapereka maulalo olembera kuti aziwunikiridwa kwanuko komanso modemu yopanda zingwe yolumikizana ndi NMS (Network Management System) yomwe imatha kuyang'anira momwe ntchito ikuyendera mobwerezabwereza ndikutsitsa magwiridwe antchito kwa wobwereza.
6, Aluminiyamu-alloy casing ali ndi mphamvu yolimbana ndi fumbi, madzi ndi kuwononga;
