62 Site planning and hardware deployment
To plan an unusual condition, consider the following situations.
•
•
•
Cell centers are too close If you deploy cell centers less than 10 metres
apart, the handsets can initiate unnecessary handover. Unnecessary
handover results in excessive internal messaging and degraded speech
quality.
Cell centers are too far apart If you deploy cell centers too far apart,
the edge of a cell does not overlap the coverage from another cell.
Cell centers must be within the edge of other cell centers to provide
satisfactory overlap.
Overlap can be difficult to achieve where coverage is received from the
floor above or the floor below. Internal structures can cause overlap
deficiencies.
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 where you can easily mount basestations.
•
Install basestations as close as possible to planned locations.
•
Follow safety codes, and be aware aesthetics.
•
Allow sufficient access to install basestations.
•
Provide clear installation instructions.
•
Test the coverage during post-deployment checks.
