To enable and configure WLANs on an Mobility 5181 Access Point radio, see “Enabling wireless
LANs (WLANs)” on page 106.
Support for 4 BSSIDs per radio
The access point supports four BSSIDs per radio. Each BSSID has a corresponding MAC address.
The first MAC address corresponds to BSSID #1. The MAC addresses for the other three BSSIDs
(BSSIDs #2, #3, #4) are derived by adding 1, 2, 3, respectively, to the radio MAC address.
If the radio MAC address displayed on the Radio Settings screen is 00:24:38:28:9B:DC, then the
BSSIDs for that radio will have the following MAC addresses:
For detailed information on strategically mapping BSSIDs to WLANs, see “Configuring the 802.11a
or 802.11b/g radio” on page 121. For information on access point MAC address assignments, see
“Mobility 5181 Access Point MAC address assignment” on page 21.
Quality of Service (QoS) support
The Mobility 5181 Access Point QoS implementation provides applications running on different
wireless devices a variety of priority levels to transmit data to and from the Mobility 5181 Access
Point. Equal data transmission priority is fine for data traffic from applications such as Web
browsers, file transfers or email, but is inadequate for multimedia applications.
Voice over Internet Protocol (VoIP), video streaming and interactive gaming are highly sensitive to
latency increases and throughput reductions. These forms of higher priority data traffic can
significantly benefit from the Mobility 5181 Access Point QoS implementation. The WiFi Multimedia
QOS Extensions (WMM) implementation used by the Mobility 5181 Access Point shortens the time
between transmitting higher priority data traffic and is thus desirable for multimedia applications.
In addition, U-APSD (WMM Power Save) is also supported.
WMM defines four access categories—voice, video, best effort and background—to prioritize traffic
for enhanced multimedia support.
For detailed information on configuring QoS support, see “Setting the WLAN Quality of Service
(QoS) policy” on page 111.
Industry leading data security
The Mobility 5181 Access Point supports numerous encryption and authentication techniques to
protect the data transmitting on the WLAN.
The following authentication techniques are supported:
• Kerberos authentication
• EAP authentication
BSSID MAC Address Hexadecimal Addition
BSSID #1 00:24:38:28:9B:DC Same as Radio MAC address
BSSID #2 00:24:38:28:9B:DD Radio MAC address +1
BSSID #3 00:24:38:28:9B0:DE Radio MAC address +2
BSSID #4 00:24:38:28:9B:DF Radio MAC address +3
