Estimating traffic within a cell To adjust the number of users supported
by the system, you can modify the deployment procedures you followed in
“Deploying on a single floor” (page 44) or “Deploying on multiple floors”
(page 59). Perform the following three steps to estimate traffic within a cell:
•
Determine the number of handset users with an office within each cell.
•
Determine how many users have wired phones.
•
Determine how many users without an office are normally in each cell.
Some users have both wired and handset phones; other users rely on
handsets only.
Re-engineered cells for high traffic areas are represented by an adjusted
estimate for the two groups: handset and wireless, and handset only. Use
the adjusted estimate to determine whether the cell sizes can handle the
telephone traffic.
If the traffic-handling capacity of the cells is not adequate, use 12-channel
basestations and subdivide them into smaller cells to ensure the traffic is
handled properly according to the instructions.
