WRH-V
Non-Diversity
Figure A-2 illustrates non-diversity block diagram configuration of the WRH-V. The WRH-V is always
fed by a BTS via either a BMU or an OCM. The TX signal from the BTS is converted to an optical
signal in a BMU or OCM and fed to the WRH-V via a fiber optic cable. The optical signal is received
by the FON and converted to an RF signal. The FON supervises the signaling and reports errors via
the RCU connected to the CU.
The RF signal enters the WBA, is amplified, and further amplified in amplifier stages followed by
controllable attenuators. The signal exits the WBA and enters the MCPA where it is amplified and fed
to the DPX. The amplified output signal passes the DPX before it is fed to the service antenna.
The uplink signal path is located on the same WBA but only has an LNA before entering the WBA.
