Here is a schematic on how this can be achieved:
3.5 Full system example
Here is an example of a full system showing the Master Unit and the fibers that goes off to the Remote
Units (not shown in this example) with multiple operators and a large number of frequency bands.
Block 1: Here are all the Base Station Interface Units (BIU) cards for all the frequency bands and the
operators. In this example two operators may share one BIU. The first unit 1:1 is for FM radio which is
only Downlink as it is broadcast. The second unit 1:2 is for a safety blue light service using the TETRA
system on 400 MHz. Then there are two BIU’s 1:3 and 1:4 for GSM 900, similar for GSM 1800 and for
UMTS 2100 and LTE 2600.
Block 2: This is the Point of Interconnect (POI) where all the signals from the operators are combined on
the four coupling fields of the first POI. There are two UL fields and two DL fields. The common ports are
then fed into a hybrid combiner and on to the second POI where the signals are split up to connect to all
the Fiber-optic Interfaces.
