AP-7131N-FGR Access Point Product Reference Guide
1.2.17 MU-MU Transmission Disallow
The access point's MU-MU Disallow feature prohibits MUs from communicating with each other even
if on the same WLAN, assuming one of the WLAN's is configured to disallow MU-MU
communication. Therefore, if an MU's WLAN is configured for MU-MU disallow, it will not be able to
communicate with any other MUs connected to this access point.
For detailed information on configuring an WLAN to disallow MU to MU communications, see
Creating/Editing Individual WLANs on page
5-32.
1.2.18 Voice Prioritization
Each access point WLAN has the capability of having its QoS policy configured to prioritize the
network traffic requirements for associated MUs. A WLAN QoS page is available for each enabled
WLAN on either the 802.11a/n or 802.11b/g/n radio.
Use the QoS page to enable voice prioritization for devices to receive the transmission priority they
may not normally receive over other data traffic. Voice prioritization allows the access point to assign
priority to voice traffic over data traffic, and (if necessary) assign legacy voice supported devices (non
WMM supported voice devices) additional priority.
For detailed information on configuring voice prioritization over other voice enabled devices, see
Setting the WLAN Quality of Service (QoS) Policy on page
5-42.
1.2.19 Support for CAM and PSP MUs
The access point supports both CAM and PSP powered MUs. CAM (Continuously Aware Mode) MUs
leave their radios on continuously to hear every beacon and message transmitted. These systems
operate without any adjustments by the access point.
A beacon is a uniframe system packet broadcast by the AP to keep the network synchronized. A
beacon includes the ESSID, MAC address, Broadcast destination addresses, a time stamp, a DTIM
(Delivery Traffic Indication Message) and the TIM (Traffic Indication Map).
PSP (Power Save Polling) MUs power off their radios for short periods. When a MU in PSP mode
associates with an access point, it notifies the access point of its activity status. The access point
responds by buffering packets received for the MU. PSP mode is used to extend an MU's battery life
by enabling the MU to "sleep" during periods of inactivity.
