Configuring Rate Settings
Use the Rate Settings screen to define a set of basic and supported rates for the target radio. This allows
the radio to sync with networks using varying data rates and allows the radio to default to a predefined set
of data rates when higher data rates cannot be maintained.
To configure Rate Settings for a radio:
1. Click the Rate Settings button within the radio edit screen to launch a new screen with rate setting
information.
2. Check the boxes next to all the Basic Rates you want supported.
Basic Rates are used for management frames, broadcast traffic and multicast frames. If a rate is selected
as a basic rate it is automatically selected as a supported rate.
3. Check the boxes next to all the Supported Rates you want supported.
Self Healing Offset When an access port increases its power to compensate for a failure, power is increased to
the country's regulatory maximum. Set the Self Healing Offset to reduce the country's
regulatory maximum power if access ports are situated close to each other or if access port
uses an external antenna. For additional information on determining the offset value, see the
documentation shipped with the access port.
DTIM Periods Select the DTIM Periods button to specify a period for Delivery Traffic Indication Messages
(DTIM) for BSS IDs 1-4. This is a divisor of the beacon interval (in milliseconds), for example,
10 : 100. (See "Beacon Interval," above). A DTIM is periodically included in the beacon frame
transmitted from adopted access ports. The DTIM period determines how often the beacon
contains a DTIM, for example, 1 DTIM for every 10 beacons. The DTIM indicates that
broadcast and multicast frames (buffered at the access port) are soon to arrive. These are
simple data frames that require no acknowledgement, so nodes sometimes miss them.
Increase the DTIM/beacon settings (lengthening the time) to let nodes sleep longer and
preserve their battery life. Decrease these settings (shortening the time) to support
streaming-multicast audio and video applications that are jitter-sensitive. The default DTIM
period is 10 beacons for BSS 1-4.
