The single band RF repeater works only on one frequency band.

It works as a relay between the BTS and mobile device. It picks up the signal from the BTS via the ‘Donor’ antenna, linearly amplifies the signal and retransmits it via the ‘Coverage’ antenna (or In-building Distributed Antenna System) to the weak or blind signal area. In the reverse direction, the mobile device signal is also amplified and retransmitted in the direction of the BTS.
