Which two Cisco Unified Wireless Network capabilities use information that is provided by Radio Resource Management neighbor messages in version 7.0 MR1?

Dynamic Channel Assignment Algorithm

The DCA algorithm, run by the RF Group Leader, is applied on a per-RF-Group basis to determine optimal AP channel settings for all the RF Group’s APs (each set of APs who can hear each other’s Neighbor Messages, referred to in this document as a logical RF sub-Group, has its channel configuration done independently of other logical RF sub-Groups due to the fact that signals do not overlap). With the DCA process, the leader considers a handful of AP-specific metrics that are taken into account when determining necessary channel changes. These metrics are:
Load Measurement—Every AP measures the percentage of total time occupied by transmitting or receiving 802.11 frames.
Noise—APs calculate noise values on every serviced channel.
Interference—APs report on the percentage of the medium taken up by interfering 802.11 transmissions (this can be from overlapping signals from foreign APs, as well as non-neighbors).
Signal Strength—Every AP listens for Neighbor Messages on all serviced channels and records the RSSI values at which these messages are heard. This AP signal strength information is the most important metric considered in the DCA calculation of channel energy.

When an AP receives a Neighbor Message (transmitted every 60 seconds, on all serviced channels, at maximum power, and at the lowest supported data rate), it sends the frame up to its WLC to determine whether the AP is a part of the same RF Group by verifying the embedded hash. An AP that either sends undecipherable Neighbor Messages (indicating a foreign RF Group Name is being used) or sends no Neighbor Messages at all, is determined to be a rogue AP.
