One of the most important points
to realize is that there are a vast number of diverse reasons why
CDMA systems may exhibit
problems. For example, parts of the system may not operate
optimally for any combination of
the following reasons:
Base station hardware
failures (including intermittent problems)
Poor RF environment
Sub-optimal cell
site location / antenna placement
Translations entry
errors or accidental changes
Translations
requiring optimization
Core network
problems (capacity overflows, hardware failures, incorrect provisioning etc.)
In correct antenna
assembly
Cell site capacity
limitations
Improper RF
optimization
