Deployment and Design Requirements

Rogue clients are simply all client devices that are associated to rogue access points.

Asset tags are any vendors' 802.11-based RF ID tags within range of infrastructure access points.

Consider the type of devices involved and how many devices will be tracked. Tracking of any of the four device types can be configured. Determine the total number of devices and plan to deploy one location appliance for every 1500 simultaneously tracked devices.

Depending on network requirements, placement of the location appliance in relation to WCS can be adjusted to fit specific site needs. Where a single WCS is used for wireless LAN management, one or more location appliances can be used to track 1500 or more devices. When multiple WCS are used to manage separate wireless LANs, a single location appliance can be used by all WCSs to track each device if the total number of tracked devices among them all does not exceed 1500.

Note If WCS and controllers are not physically co-located or have fast connections between them, deploy the location appliance(s) as close as possible to WCS. Network diagrams (floor plan maps and the access point locations on those maps) are synchronized between both devices.

Designing the Wireless LAN for Location

The Cisco Aironet 1000 series access points are supported by the Wireless LAN Controllers (2000-, 4100, and 4400-series controllers as well as Cisco Catalyst 6500 Series Wireless Services Module (WiSM) which forward device information up to the location appliance. Antenna configuration on these access points is important. The internal antenna of the Cisco Aironet 1000 series access point allows for device location tracking, as do external antennas supported on both those access points. Select models of the 1100 and 1200 series Cisco Aironet access points are also supported: Cisco Aironet 1240AG, 1230AG, 1200 series containing 802.11g such as AIR-MP21G-x-K9, second generation 802.11a radios such as AIR-RM21A-x-K9 or AIR-RM22A-x-K9, and Aironet 1130AG.

Note WCS allows you to add non-Cisco antennas and their gain; however, no location or coverage maps are generated for these non-Cisco antenna nor will they be TAC supported.

Below is the list of external Cisco antennas that conform to TAC supported configurations:

•AIR-ANT-4941

•AIR-ANT-1729

•AIR-ANT-1728

•AIR-20122410Y-R

•AIR-ANT-2506

•AIR-ANT-3213

•AIR-ANT-3549

•AIR-ANT-4941

•AIR-ANT-5959

•AIR-ANT-5135D-R
