Calculating the number of users inside the cell with an office
1. Estimate the number of users in the first cell with an office.
Use the formula: (users with an office in the cell × 0.7)
2. Enter the result in the row Users inside the cell with an office.
In the example in Figure 33: Example of dividing the coverage area and recording
offices on page 63, 12 users in cell 1C1 spend 70 percent of their time in their of
fices
(12 × 0.7 = 8.4) .
Traffic engineering demonstrates that handset users with an office spend 70 percent of their
time within their home cell.

Calculating the number of users with an office outside the cell who walk into the
cell
1.
Estimate the number of users in the first cell with an office outside of the cell who
walk into the cell.
2. Use the following formula:
3. Enter the result in the row Users with an office outside the cell who walk into the
cell.
The example in Figure 33: Example of dividing the coverage area and recording
offices on page
63, shows 75 telephone users, minus the 12 users already in cell
1C1. Therefore, 63 users can walk into cell 1C1. However, the 63 walk-in users
spend only 30 percent of their time outside their offices. Seven cells exist on the
floor plan minus cell 1C1. Accordingly, an estimate of 3.2 walk-in users can be in
cell 1C1.
