Cellular telephone systems transmit signals in two directions between base 
transceiver station (BTS) and mobile stations (MS) within the signal coverage area. 
 
If weak signal transmissions occur within the coverage area because of indoor 
applications, topological conditions or distance from the transmitter, a repeater is 
used to extend transmission range. In the downlink (DL) path, the repeater picks up 
the signal from a donor antenna of an existing cell, processes and retransmits it into 
the desired dark spot. In the uplink (UL) direction, the repeater receives a signal from 
mobile stations present in its coverage area and forwards them to the corresponding 
BTS. 
 

 
The repeater MRx03P is a band selective amplifier which bi-directionally amplifies 
signals between a base transceiver station and mobile stations in the corresponding 
network. It can provide highly selective amplification, thus enabling radio coverage in 
regions where satisfactory quality of communication is disabled. The following figure 
shows the configuration of a MIKOM repeater MRx03P.

The MRx03P can also be combined with other repeater systems to create a 
combined repeater system. When different modules are combined, a common 
antenna terminal and a common control interface is available.
