Procedure 26
Determining cell reengineering
Step Action
1 Locate the estimate for users in the first cell.
In the example shown in Table 16 "Example of a completed
estimate table" (page 91), the handset estimate is 11.6.
2 Determine the telephone types in the first cell.
In the example shown in Table 16 "Example of a completed
estimate table" (page 91), the telephone type is H&W.
3 Locate the telephone type column in Table 16 "Example of a
completed estimate table" (page 91).
In the example H&W is the users with both a handset and a
wired telephone.
4 Find the handset estimate range in Table 18 "Cell reengineering"
(page 91).
In the example, 11.6 falls within the From 0 up to 20 category.
5 Determine if a cell requires division or uses a 12-channel
basestation.
In the example From 0 up to 20, division is not required.
6 Repeat the preceding steps to determine the required number of
cells that need subdivision, except for telephone types M. For M
see “A mix of users with and without wired telephones in a cell”
(page 93).
7 Transfer the results into the provisioning records.

Cell division requirements in special cases
This section describes how to determine cell division in the following
special cases.
• Where no office information is available.
• Where there is a mix of handset users with and without wired
telephones.
No office information
If the location of the offices of users is not known, calculate the estimated
number of handsets for each cell using this formula.
