Figure 9. 2+2 dual band configuration
Another way to build overlapping GSM/EDGE 900 and GSM/EDGE 1800 cells,
is to direct single band GSM/EDGE 900 and GSM/EDGE 1800 antennas towards
the same direction.
The Nokia MetroSite EDGE Base Station can be used to build fill-in coverage in
areas that are difficult to reach with conventional base stations. In these cases, it
is recommended that high-gain antennas are used.
Antennas directed to form one coverage area including
2 GSM/EDGE 900 TRXs + 2 GSM/EDGE 1800 TRXs.
