System synchronization analysis 221
• Tree view
The Tree view pane shows a hierarchical view of the synchronization
tree. In the tree view, you can select a DAP.
• Visibility Information
The Visibility Information pane shows an overview of the RSSI values.
— The RSSI (sees) column indicates the signal strength with which
the selected DAP sees the other DAPs.
— The RSSI (seen) column indicates the signal strength with which
the other DAPs see the selected DAP.
Although the radio signal connection is reciprocal there can be
differences in the seen and sees RSSI value. This difference is caused
by the fact that this visibility information is based on a snapshot.
The RSSI values are hexadecimal in the range: 0 ... e., , where 0
indicates no signal. The -80 dBm boundary is found at the boundary
between approximately 3 and 4. Generally, the Phase difference must
be ffffffff with a maximum deviation of 7 (higher or lower).
