In the reverse link, the radio signals received from the antenna run
through the LPA of RFE to the TRX for down-conversion processing.
They become IF signals first, undergo digital IF processing, then turn
into sample signals of the BDS, and are finally sent to RMM. RMM puts
all data sent from TRX into a packet and sends it to BDS.
The GCM board in BDS provides clock signal for RIM. RIM then
provides RFS with the clock signal.
Technological Advantages of RFS
LRFS and RRFS are both RFS but with different applications. As one
BTS may have no more than one LRFS, it may connect to several
RRFSs. While LRFS is always set up in the same equipment room as
the BDS, RRFS can be placed miles away from the BDS in the cave,
subway or other irregular locations.
BDS and RFS can be connected in the star, chain or ring networking
modes through the RIM.
One TRX may provide the capacity of 4 carriers and adopt the LPA for
4 carriers.
In a single cabinet, there can be 12 carrier sectors (1~4 carriers × 1~3
sectors).
