Reservation Threshold

If you enable medium reservation, you need to set a threshold
value, which is the largest data frame that can be transmitted
without reserving air time. Air time is normally reserved to help
prevent collisions with other transmitters.

Distance Between APs

Controls the roaming sensitivity of your end devices. This setting
should match the setting on your end devices.

You can use this parameter to virtually reduce the range of your
access point. If you choose Small or Medium, you do not reduce
the absolute range of your radio, but you modify the collision
detection mechanism to allow significant overlap of the wireless
cells. Thus, you create a higher performance radio network, but
you need more access points to cover an area.

Enable Microwave Oven Robustness

Determines if the access point activates a modified algorithm for
automatic rate fallback, which prevents the access point from
falling back to 1 Mbps when trying to retransmit radio frames
when 2.4 GHz interference is present.

Enable Load Balancing

Determines if end devices can distribute their connections across
multiple access points.

Enable Medium Density Distribution

Determines if these access point parameters: Enable Medium
Reservation, Distance Between APs, Enable Microwave Oven and
Robustness are distributed to end devices that support this
feature.

Data/Voice Settings (Master radio only)

Choose the setting that optimizes the wireless network.

Set to Data Traffic Only if the access point will transmit only data
traffic.

Set to SpectraLink Traffic Only if the access point will transmit only
voice traffic. SpectraLink telephone frames will be sent with a
priority setting. All other multicast/broadcast frames will be
dropped.

Set to Data and SpectraLink Traffic if the access point will transmit
both data and voice traffic. SpectraLink telephone frames will be
sent in the high priority queue. Frames in the high priority queue
are sent ahead of frames in the normal priority queue. No special
filtering.
