2. FUNCTIONAL DESCRIPTION
2.1. GENERAL
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.
2.2. REPEATER DESIGN
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.
