1Introduction to the BSS Configuration andAdjustment
About This Chapter
This describes the definition of a BSS configuration and adjustment, relations between some
correlated scenarios, and methods and tools required for performing the BSS configuration and
adjustment.
1.1 Definition of the BSS Configuration and Adjustment
The BSS network adjustment refers to software or hardware adjustments of the BSS system a
Recommended
