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 can range from 0
to infinity, although in most normal environments the RF Pollution index will average
between 10 and 100. Higher values indicate a noisier environment.
• What is RF Pollution measuring? It is measuring the level of RF contention and
interference experienced by the AP. It distills several low-level MAC and PHY-level
error metrics into a single parameter.
• How is RF Pollution different than noise? Noise may or may not have an impact on
performance. RF Pollution is a measure of noise or other interference that is in fact
impacting performance.
• How do customers use this new concept to understand and manage their WiFi
networks? RF Pollution is an informational metric. BeamFlex and ChannelFly use a
variant of this metric and other throughput-based metrics internally to optimize the
RF so that you don't have to.
• Why is Ruckus using this new term vs. the existing measurements such as PHY
errors, CRC errors, etc.? PHY Errors and CRC errors can be very misleading metrics
because there is no standard way for the chipset to report them. Different chipsets
can report these errors in different ways and certain types of noise can even mask
these errors entirely. RF Pollution is a more stable metric that will never produce
misleading results.
