POI can provide isolation, division and combination for
different systems, effectively suppressing spurious emission
interference, barrage jamming and PIM. It avoids resource
waste from repeated construction of carriers' signal
distribution systems, thus reducing the construction and
maintaining cost substantially.
It can be used for co-construction and sharing coverage in
large construes, such as hotels, stadiums, conference and
exhibition centers, airport and suyway.
