Wi-Fi Location-Based Services—Design and Deployment Considerations
OL-11612-01
Cisco Location-Based Services Architecture
Note Currently, each WLAN controller is capable of supporting up to 500 802.11 L2 active RFID tags.
To display RFID asset tags on the WCS location floor map, ensure that the “Show 802.11 Tags” view
option is selected at the top of the floor map display and then click Reload in the left-hand column. Note
that it is assumed that all other components of the LBS system have been properly configured to collect
asset tag information. For more information, see Enabling Asset Tag Tracking for L2 Multicasting Asset
Tags, page 95.
Figure 16 WCS RFID Tag Location Map
Note that beginning with Release 4.0 of WCS, it is possible to filter the location information displayed
by WCS based on the age of the information. Thus, in Figure 16, WCS displays location server
information that has aged up to 15 minutes. Alternatively, this value could be set to 2 or 5 minutes for
more recent location information, or ½, 1, 3, 6, 12, or 24 hours for less recent information.
Several options are available by clicking on the yellow tag icon under “View Filters”:
• The total number of asset tags detected on this floor.
• Small icons (shown above) or regular-sized icons can be selected. When using small icons, no text
is displayed on the floor map for the asset tag except when a mouse-over is performed. When using
regular-sized icons, an on-screen tag is displayed, which is configurable for MAC address, asset
name, asset group, or asset category.
• Either all asset tags can be displayed or filtering can be performed to select which asset tags to
display on the floor map. This can be based on MAC address, asset name, asset group, asset
category, or controller.
