Installation plan
- Establish the locations of the base stations from the results of the on-site inspection and enter
their positions in the plan of the building.
If typical propagation levels were measured in a typical area, then the locations of the
base stations can be theoretically determined by using the radius "r" of a radio cell.
- Check whether installation is possible using these theoretically obtained values. Make any
necessary corrections.
- Within buildings, FPs should be installed centrally. Avoid installing near or on external
walls.
- Install FPs in a single row, if possible.
- In the case of broad areas, install the FPs in several rows.
-
Install the FPs in the rows in such a way that their footprints overlap.
The above diagram is an idealised representation of radio cells.
- HF signals from the floors below or above should not be taken into account in the planning
of FP locations.
