4.5.3 Modifying Wireless AP radio properties
Most properties of the Wireless AP radios can be modified without requiring a
reboot of the Wireless AP. However, if the modification of a Wireless AP property
does trigger a reboot, the Wireless AP property is identified with a red asterix in
the HiPath Wireless Assistant.
Note: Modifying Wireless AP radio properties can vary significantly depending on
the model of the Wireless AP your are configuring:
• For specific information on modifying a Wireless 802.11n AP, see Section
4.5.3.1, “Modifying Wireless 802.11n AP 3610/3620 radio properties”, on page
96.
• For specific information on modifying a Wireless AP 2610/2620 or HiPath
Wireless Outdoor AP, see Section 4.5.3.2, “Modifying Wireless AP 2610/2620
radio properties”, on page 106.
Dynamic Radio Management (DRM)
When you modify a Wireless AP’s radio properties, the Dynamic Radio
Management (DRM) functionality of the HiPath Wireless Controller is used to help
establish the optimum radio configuration for your Wireless APs. DRM is enabled
by default. The HiPath Wireless Controller’s DRM:
• Adjusts transmit power levels to balance coverage between Wireless APs
assigned to the same RF domain and operating on the same channel.
• Scans and coordinates with other Wireless APs to select an optimal operating
channel.
Note: The Wireless 802.11n AP does not support the DRM functionality of the
HiPath Wireless Controller.
The DRM feature is comprised of two funtions:
• Auto Channel Selection (ACS) – ACS provides an easy way to optimize
channel arrangement based on the current situation in the field. ACS provides
an optimal solution only if it is triggered on all Wireless APs in a deployment.
Triggering ACS on a single Wireless AP or on a subset of Wireless APs
provides a useful but suboptimal solution. Also, ACS only relies on the
information observed at the time it is triggered. Once a Wireless AP has
selected a channel, it will remain operating on that channel until the user
changes the channel or triggers ACS. ACS can be triggered by one of the
following events:
• A new Wireless AP registers with the HiPath Wireless Controller and the
AP Default Settings channel is Auto.
