76 Site planning and hardware deployment

"Cell reengineering" (page 72). Subdivide high handset density areas only.

If a cell falls into the category of a high density area, use Procedure 26

“High handset density deployment” (page 76) to subdivide the cell.

Subdivide a cell To subdivide the area for smaller cells, divide the cell

into as many small cells as necessary to accommodate the number of

users in the area.

ATTENTION

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 33

Example of a subdivided cell

In Figure 33 "Example of a subdivided cell" (page 76), cell 1C1 has 140

handset users and cell 1C2 has 100 handset users. For example, Table

14 "Cell reengineering" (page 72) 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).

Procedure 26

High handset density deployment

Step Action

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.
