1.3 System Architecture
Figure 1-2 illustrates the MRU system architecture. In the downlink, At the headend, RF signals from the base transceiver
stations (BTS) or bidirectional amplifiers (BDA) are conditioned by service-specific radio interface modules (RIMs) in the
headend unit (i.e. HEU/IHU), ensuring a constant RF level. The conditioned signals are then forwarded to the optical interface
unit (OIU) and converted by the optical interface modules (OIM) to an optical signal for transporting over single-mode fiber to the
MRU at the remote location. In the uplink, the process is reversed.
All mobile services are combined and distributed through a single antenna port over the broadband antenna infrastructure
installed at the remote locations.
