Client Roaming
High-speed roaming of Cisco Compatible Extension (CX), version 4 (v4) clients is supported at speeds up to
70 miles per hour in outdoor mesh deployments of AP1522s and AP1524s. An example application might be
maintaining communication with a terminal in an emergency vehicle as it moves within a mesh public network.
Three Cisco CX v4 Layer 2 client roaming enhancements are supported:
• Access point assisted roaming—Helps clients save scanning time. When a Cisco CX v4 client associates
to an access point, it sends an information packet to the new access point listing the characteristics of
its previous access point. Roaming time decreases when the client recognizes and uses an access point
list built by compiling all previous access points to which each client was associated and sent (unicast)
to the client immediately after association. The access point list contains the channels, BSSIDs of neighbor
access points that support the client’s current SSID(s), and time elapsed since disassociation.
• Enhanced neighbor list—Focuses on improving a Cisco CX v4 client’s roam experience and network
edge performance, especially when servicing voice applications. The access point provides its associated
client information about its neighbors using a neighbor-list update unicast message.
• Roam reason report—Enables Cisco CX v4 clients to report the reason why they roamed to a new access
point. It also allows network administrators to build and monitor a roam history.
Client roaming is enabled by default. For more information, see the Enterprise Mobility
Design Guide at http://www.cisco.com/en/US/docs/solutions/Enterprise/Mobility/

Note
WGB Roaming Guidelines
Follow these guidelines for WGB roaming:
• Configuring a WGB for roaming—If a WGB is mobile, you can configure it to scan for a better radio
connection to a parent access point or bridge. Use the ap(config-if)#mobile station period 3 threshold
50 command to configure the workgroup bridge as a mobile station.
