Figure 17: Cell boundary terminology
Determine a cell boundary for the cell center by placing the deployment tool at the cell center
and using the deployment handset to establish the cell boundary.
Use the following procedure to mark the cell contour based on the most distant point.
Demarcating the cell contour for the critical point farthest from the center of the
full coverage area
1. Set up the deployment tool basestation. Raise the deployment tool basestation as
high as possible, or until it is at the height recommended for basestations.
2. Enter the site survey mode on the handset.
For more information, see Entering the site survey mode on page
43 if you use
Deployment Kit 2, or
Entering the monitor mode on page
213 if you use an older
Deployment tool.
3. Measure the range into the coverage area in a few directions to determine where a
cell center can be located and still be within range of the critical point.
Listen to the deployment tool handset while moving away from the basestation. After
the RSSI value changes from 7 to 6 (--80dBm to --85dBm), the cell boundary is
detected.
For more information about deployment requirements, see
Radio
synchronization on page 19.
4.
Mark the cell boundary on the floor plan with a small x.
5. Repeat step 3 and step 4 until you have sufficient Xs to draw a thin contour arc
through the Xs.
