3.11.2 Procedure Overview
When connecting the wireless system, use extreme care in conducting the site survey. An incorrectly performed
site survey can result in poor service area, frequent noise, and disconnection of calls.
Notice
•
When installing the DECT 6.0 wireless system in an area where another wireless system (2.4 GHz) is
already installed, it is necessary to reconduct the site survey to find the optimum position for the CS.
If you install the new CS in the same position as the old CS, it may result in a poor service area, frequent
noise, and disconnection of calls.
•
In this case, it is necessary to perform system initialisation. For details about the system initialisation
procedure, refer to "3.16 Starting the PBX".
1. Investigate the installation site
Refer to "3.11.3 Site Planning".
a.
Obtain a map of the CS installation site.
b.
Identify the service area required by the user on the map.
c.
Plan the location of each CS, taking account of distance, building materials, etc.
2. Prepare for site survey
Refer to "3.11.4 Before Site Survey".
a.
Check and assign the CS ID number to the PS.
b.
Assign a channel number to each CS by setting the DIP switches on the back of the CS.
c.
Supply electricity to each CS using an AC adaptor/battery box or by connecting them to the PBX.
d.
Install each CS temporarily as planned.
Note
•
Install at least 2 m above the floor.
•
Place the antennas so that they are pointing in directions that are 90 degrees apart (for antenna
diversity).
3. Conduct the site survey
Refer to "3.11.5 Site Survey".
a.
Test the radio signal strength using the PS.
Confirm that the radio signal strength level is "12" near the CS.

b.
By walking away from the CS with the PS, check the radio signal strength. The radio signal strength
weakens as you walk away from the CS.
c.
Map the CS coverage area at radio signal strength levels "3" and "8".
d.
Make sure that adjacent CS coverage areas meet where the radio signal strength level is "7" to "9".
e.
Make sure that the radio signal strength level is greater than "3" at any location within the service area
required by the user.
