DMS-MTX DualMode Metrocell Cell Site Description
Receive cabling
In the reverse path, the receive signal from the main antenna of each sector is
connected to the A-input of the Receive Multicoupler (RMC) through the
receive port of the duplexer of that sector. The diversity antenna connects
directly to the B-input of the RMC. Distribution of the reverse path
frequencies is accomplished by RF splitters within each RF frame.
Table 3-8 lists the connection between the RMCs and the RF splitters in a
120
°
STSR Metrocell with one RF Frame. Table 3-9 lists the connection
between the RMCs and the RF splitters in a 120
°
STSR Metrocell using three
RF frames.
