Feature overview

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 Mobility 5181
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”
Support for CAM and PSP clients
The Mobility 5181 Access Point supports both CAM and PSP powered Clients. CAM (Continuously
Aware Mode) Clients leave their radios on continuously to hear every beacon and message
transmitted. These systems operate without any adjustments by the Mobility 5181 Access Point.
A beacon is a uniframe system packet broadcast by the AP to keep the network synchronized. A
beacon includes the ESSID, Mobility 5181 Access Point MAC address, Broadcast destination
addresses, a time stamp, a DTIM (Delivery Traffic Indication Message) and the TIM (Traffic
Indication Map).
PSP (Power Save Polling) Clients power off their radios for short periods. When a Client in PSP
mode associates with an Mobility 5181 Access Point, it notifies the Mobility 5181 Access Point of
its activity status. The Mobility 5181 Access Point responds by buffering packets received for the
Client. PSP mode is used to extend an Client’s battery life by enabling the Client to “sleep” during
periods of inactivity.
Statistical displays
The Mobility 5181 Access Point can display robust transmit and receive statistics for the WAN and
LAN ports. WLAN stats can be displayed collectively and individually for enabled WLANs. Transmit
and receive statistics are available for the Mobility 5181 Access Point’s 802.11a and 802.11b/g
radios. An advanced radio statistics page is also available to display retry histograms for specific
data packet retry information.
Associated Client stats can be displayed collectively and individually for specific Clients. An echo
(ping) test is also available to ping specific Clients to assess association strength. Finally, the
Mobility 5181 Access Point can detect and display the properties of other APs detected within the
Mobility 5181 Access Point’s radio coverage area. The type of AP detected can be displayed as well
as the properties of individual APs.
For detailed information on available Mobility 5181 Access Point statistical displays and the values
they represent, see
Transmit power control
The Mobility 5181 Access Point has a configurable power level for each radio. This enables the
network administrator to define the antenna’s transmission power level in respect to the access
point’s placement or network requirements as defined in the Mobility 5181 Access Point site
survey.
For detailed information on setting the radio transmit power level, see
