RF Pollution FAQ
• What is RF Pollution?
“RF Pollution” is a linear index used to describe the level of performance-
impacting RF contention and interference that an AP is experiencing. It distills
several low-level mac and phy-level error metrics into a single parameter. Values
Performance Displays a graphical view of AP performance and RF
environment statistics. Three Performance analysis graphs
plot the capacity, throughput, associated clients and RF
contention in the channel as a function of time. The
estimated capacity is the maximum potential throughput
of a particular client or the current mix of clients. This
estimate is based on measurements of downlink traffic and
is updated only when the AP transmits more than 1000
packets, each containing at least 1024 bytes of data,
within a one-minute measurement interval. The uplink and
downlink throughput curves show the actual throughput
of a particular client or the current mix of clients. These
curves are influenced by the user session, and they vary
as a function of gaps in browsing activity and internet
server response times.
The RF Pollution graph plots a proprietary metric
describing the impediment due to other RF signals
competing for use of the channel over time. (*See
RF
Pollution FAQ for more information.)
Neighbor APs Displays nearby APs, their channel and signal strength.
Mesh-related Information Displays uplink/downlink information, transmission
statistics and details on mesh signal strength and stability
(if mesh is enabled).
Sensor Information Displays AP orientation and temperature details as
reported by the AP’s internal sensors (not supported on all
APs). See
“Orientation” below for more information.
Clients Displays a list of the currently connected clients. Action
icons can be used to configure or troubleshoot a client from
this list.
Events Displays an AP-related subset of the All Events / Activities
table.
