82 Site planning
Overlap can be difficult to achieve where coverage is received from the
floor above or the floor below. Internal structures can cause overlap
deficiencies.
Cell centers do not need to be located on the same floor or an adjacent
floor of the area that it is covering. Place cell centers within the cell
boundary, as indicated by the deployment tool.
The installation of basestations in places other than the location shown on
the plan can cause coverage problems; for example, if the basestation is
mounted on the opposite side of a wall from its planned location.
Consider the following for basestation locations.
•
Choose locations only where it is possible to mount basestations.
• Install basestations as close as possible to planned locations.
•
Follow safety codes or aesthetic considerations.
•
Allow sufficient access for installation of basestations.
•
Provide clear installation instructions.
• Test the coverage during post-deployment checks.
Too many cell centers The primary concern with deploying too many
cell centers is cost. To deploy the correct number of cell centers and
reduce cost, perform the following.
•
Verify the coverage and traffic volume before adding additional cells.
•
Remove a cell served by other cells unless it is required for high
handset density.
•
Verify the coverage area of each cell.
• Verify that there is at least one area that each cell serves that is not
served by another cell.
In the example shown in Figure 48 "Locating redundant cells" (page 83),
cell 1C3 is redundant unless required for high handset density.
