Planning An Area Of High Portable Density - Nortel Meridian Companion Reference Manual

Planning an area of high portable density

Note: Only use the high portable density procedure in this section if instructed
When you plan an area of high portable density, your first objective is to keep
the anticipated number of portables for each cell center less than or equal to
44 if the users have desk telephones in their offices and 23 if the users do not
have desk telephones.
Your second objective is to ensure that each link connects to the closest cell
center by confirming that the -45 dBm contours of different cells do not
overlap (they may do so marginally if necessary).
Only replan the areas of the site that have a high portable density. Measure the
-45 dBm contour the same way you measure the cell boundary value, but do
not use the tone (see "Using the CDT to determine cell boundaries" on
page 19). If you set the tone to change at -45 dBm, the tone will not reset to let
you make several measurements. Keep the setting for the tone at the cell
boundary value and use the display for measuring the -45 dBm contour.

to do so from Table 8 on page 38.
Count the number of users in the area of high portable density. Include
any floors above and below as well (if applicable).
Divide the number of users by 44 or 23. Round up the result to the next
whole number. This figure is the number of cells you need to plan in the
high portable density area.
Measure with the CDT the cell boundary contour and the -45 dBm
contour of one cell in the high portable density area. If the building
requires coverage on adjacent floors, include these floors as well.
Estimate the location of the cell centers where the -45 dBm contours of
the cells will not overlap and the cell boundary will cover the required
area. Use the number of cells as calculated in step 2.
With the CDT, verify and record the cell centers you planned on paper
in step 4. You must verify the -45 dBm contour and the cell boundary
contour. Include any adjacent floors above or below as required.
If there are gaps in the coverage or the -45 dBm contours overlap, repeat
step 4.
