Figure 20. Recommended orientation for optimal performance
Point to Multipoint Orientation
In a point to multipoint configuration, there are many factors to consider. First, note
that the maximum angle from the Root Bridge is 30 degrees. As you get closer to the
maximum angle from the Root Bridge, throughput performance decreases. If you go
beyond 30 degrees, performance will be drastically impacted to the point that the
connectivity may be lost entirely.
Second, consider the difference in distance from the Root Bridge. If one Non-Root
Bridge is at placed at the maximum distance from the Root Bridge (approximately 20
km), and the other is very close, performance may be impacted due to different time
delays between the two transmission links.
Some examples of recommended and non-recommended orientations are below.
