Site Survey Preparation
1.
Obtain a map and investigate the installation site.
a.
Check the obstacles (e.g., shelves, columns, and partitions).
b.
Check the materials of the structures (e.g., metal, concrete, and plywood).
c.
Check the layout and dimensions of the room, corridor, etc.
d.
Write down the above information on the map.
2.
Examine the service area required by the user on the map.
a.
Examine the coverage area for air synchronization.
Draw the coverage area around a CS. Extend the coverage area 20 m to 40 m (65 ft to 131 ft) in each
direction, depending on the materials of the building structures and obstacles in the installation site.
Note that a CS cannot be installed outside a building.
b.
Examine the coverage area for establishing conversations using PSs.
Draw the coverage area around a CS. Extend the coverage area 20 m to 50 m (65 ft to 164 ft) in each
direction, depending on the materials of the building structures and obstacles in the installation site.
c.
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.
3.
Keep a record of the air synchronization tree for reference.
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.
