b.
If 1 CS cannot cover the entire service area, install additional CSs as required. Overlap the coverage
areas of adjacent CSs.
Where CS coverage areas overlap, the PS will start call handover to the next CS if the signal from one
CS becomes weak. However, if a PS moves away from a CS and there are no CSs available for
handover, the PS may go out of range and the call could be lost.
Example: Installing in a Room Separated by Interior Walls
Things to take note of:
•
The room is separated by interior walls.
•
The room is surrounded by concrete walls.
CS installation plan:
•
The coverage area of each CS will not extend as far as when there are no obstacles, because the radio
signals will be weakened by separating walls. Therefore, you will need 5 CSs to cover the entire room.
