KingTone Dual Band Fiber Repeater is designed to integrate dual band systems, and extend the mobile signal via the distributed antenna system for indoor coverage or transmitted the signal through the fiber optic cable to a distant area for providing or improving coverage.
Optional remote monitoring function can be used as the tool to remotely monitor and control the Dual Band Fiber Optic Repeater.
Indoor/Outdoor 3G 4G LTE Repeater Cell Phone Signal Booster 1700/2100MHz / 850MHz Dual Band Repeater Amplifier over Fiber Optic Cable used in Mexico B5 for 3G and B4 for 4G.
How does fiber optic repeater work?
KingTone Best Cell Phone Signal Amplifier -Fiber Optic Repeater is designed to solve problems of weak mobile phone signal in such place: far away from the BTS (Base Transceiver Station) and has fiber optic cable network underground.
The whole FOR system consists of two parts: Donor Unit / Master Unit (DOU /MOU) and Remote Unit (ROU). They transparently convey and amplify the wireless signal between the BTS (Base Transceiver Station) and mobiles via fiber optic cables.
The Donor unit captures the BTS signal via a direct coupler closed to the BTS (or via open air RF transmission through the Donor Antenna), then converts it into optic signal and transmits the amplified signal to the Remote Unit via fiber optic cables. The Remote Unit will reconvert the optic signal into RF signal and provide the signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and re-transmitted to the BTS via the opposite direction.
