a 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.
b Establish a link. See “Deployment tool” (page 52) for details.
c 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, the cell boundary is
detected.
d Mark the cell boundary on the floor plan with a small x.
e Repeat step c and step d until there are enough Xs to draw a
thin contour arc through the Xs.
In Figure 16 "Cell contour of the initial critical point" (page 43),
P1 is the initial critical point.
3 Demarcate the cell contour of the closest adjacent critical point
to the first critical point.
See step 2 for details. In Figure 17 "Cell contour of the closest
adjacent critical point to the initial critical point" (page 44),P2is
the closest adjacent critical point to the first critical point.
4 Use the cell contours to locate a cell center.
Locate the cell center where the cell contours meet. Choose a
position on the floor plan that meets the following requirements.
• is furthest from the critical points,
•
still provides good audio quality at the critical point,
• complies with the “Rules and guidelines to locate cell centers”
(page 35), and
•
is in the coverage area.
With a pencil, label the cell center on the floor plan with the
following symbol. xCn, where x = the floor and n = is the cell
number in sequence of the entire plan.
In Figure 18 "Example of a cell center" (page 44), IC1 is a cell
center.
5 Demarcate a cell boundary.
To demarcate a cell boundary, perform the following steps.
a Set up the deployment tool basestation at the cell center.
b Establish a link.
