Important:
If you install two DAPs close to each other for extra traffic density, ensure the distance
between the DAPs is always more than one meter and preferably more than 5 meters.
Figure 34: Example of a subdivided cell
In Figure 34: Example of a subdivided cell on page 72, cell 1C1 has 140 handset users and
cell 1C2 has 100 handset users. For example, Table 14: Cell reengineering on page 68
indicates the following:
• If the handset users in cell 1C1 are all handset only users, one cell can support 39 handset
only users. Therefore, four cells are needed to support 140 users (140÷39 = 3.5 cells).
• If the handset users in cell 1C1 are handset and wired telephone users, and one cell can
support 83 users, two cells are needed to support 140 handset and wired telephone users
(140 ÷ 83 = 1.6 cells).
High handset density deployment
1. Determine the number of handset users in the high-density handset cell.
Count the number of users. Include users served by through-the-floor coverage of
this cell.
2. Calculate the cell subdivisions as required.
Divide the number of users by the appropriate value (12 or 20) shown in Table 14:
Cell reengineering on page 68. Round up the result to the next whole number. The
result equals the number of cells required after subdividing the cell.
3. Divide the cell.
Draw lines from the cell center to the critical points on the cell boundary. In Figure
34: Example of a subdivided cell on page 72, the cell 1C1 is divided into four sectors
and cell 1C2 is divided into three sectors.
4. Relocate new cell centers.
Mark new cell centers within the sectored areas.
5. Determine the number of handset users in the new cell areas.
6. Count the number of user offices within each smaller sector. Ensure fewer user
offices exist within the cell than the traffic limit.
