APs that lose the negotiation phase return to the scanning phase. A new scan takes approximately 15
seconds after which a new round of negotiating takes place.
The distributed nature of this algorithm results in an optimum distribution of channels over a large
number of APs. The maximum amount of time required to select channels is approximately 3 minutes.
In a large and dense deployment of APs, many groups of APs pick channels simultaneously. Each
round causes more and more APs to select appropriate channels in parallel. Even in dense deployments,
an AP will acquire the selected channel after approximately three rounds of negotiating
Management
DRM is configured and monitored centrally. The configuration of DRM consists of:
1 enable/disable DRM – global and per Access Point settings
2 group DRM configuration
3 enable/disable the avoidance of other WLANs
4 override channel assignment
5 Restart DRM (resetting of channel and power).
6 Type of shaped coverage (standard versus shaped)
7 Max/Min RF power configuration
When DRM is enabled, both channel and transmit signal strength are automatically configured by
DRM. Upon power-up, DRM will scan the WLAN network to select a channel and set its power to
maximum. It will back-off its power to adjust for the presence of neighboring disabled DRM Access
Points.
The DRM application is enabled globally on the Summit WM. This means that a Summit WM with the
DRM software key will enable DRM on all APs with R2.1 or higher software. It is also possible to
configure DRM on a per AP basis. Figure 3 shows the configuration page when DRM is enabled via
software keys.
