2.8 Connection of 2.4 GHz Portable Stations
b.If one 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.
If the signal from the CS fades, due to the structure of the building, there may be some handover delay. The user will hear a range warning before handover in this case. This also applies in the case of interference from 2.4 GHz apparatus.
Example: Installing in a Room Separated by Walls
Things to take note of:
•The room is separated by walls.
•The room is surrounded by concrete walls.
CS installation plan:
•The coverage area of each CS will not extend as much it does where there is no obstacle, because the radio signals will be weakened by separating walls. Therefore, you will need 5 CSs to cover the entire room.
