== Action 1: Reduce the beacon frequency ==
* Action 1: Reduce the beacon frequency <trac>7900</trac>
* Action 2: Reduce probe request frequency and probe response retry number

The beacon frequency should be reduced from its current default value of 10Hz to 1Hz.

Pros: This will save a significant amount of airtime, see [http://wiki.laptop.org/go/Wireless_Management_Traffic the Wireless Management Traffic page] for analysis.

Attention: This will impact current contention window adaptation logic that expects the beacon frequency to be 10Hz.

'''TICKET:'''

Task list:
# Marvell: please comment on the contention window adaptation logic, confirming or not that , and proposing a solution (new firmaware release?)
# Cozybit: please clarify if the default value is set on the driver

== Action 2: Reduce probe request frequency and probe response retry number ==

XOs should send out probe requests less frequently
