1.3 System Architecture

Figure 1-2 illustrates the MRU system architecture. In the downlink, at the headend, the BTS/BDA signal is conditioned at the
headend unit (e.g. integrated headend unit IHU)), by the service specific radio interface modules (RIM), ensuring a constant RF
level. The conditioned signals are then 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 infras truc tur e
installed at the remote locations.
