Adding Chokepoints to Maps

To add a chokepoint to a map, follow these steps:

Step 1 Choose Maps > Wireless Maps > Site Maps .

Step 2 Click the link that corresponds to the floor location of the chokepoint.

Step 3 From the Select a command drop-down list, choose Add Chokepoints .

Step 4 Click Go .

The Add Chokepoints summary page lists all recently-added chokepoints that are in the database but not yet mapped.

Step 5 Select the check box next to the chokepoint that you want to place on the map.

Step 6 Click OK .

A map appears with a chokepoint icon located in the top-left hand corner. You are now ready to place the chokepoint on the map.

Step 7 Left-click the chokepoint icon and drag and place it in the proper location.The MAC address, name, and coverage range of the chokepoint appear in the selected chokepoints detail page when you click the chokepoint icon for placement.

Step 8 Click Save .

You are returned to the floor map and the added chokepoint appears on the map.

The newly created chokepoint icon might or might not appear on the map depending on the display settings for that floor.

The rings around the chokepoint icon indicate the coverage area. When a CCX tag and its asset passes within the coverage area, location details are broadcast, and the tag is automatically mapped on the chokepoint coverage circle. When the tag moves out of the chokepoint range, its location is calculated as before and is no longer mapped on the chokepoint rings.

Step 9 If the chokepoint does not appear on the map, select the Chokepoints check box located in the Floor Settings menu.

Do not select the Save Settings check box unless you want to save this display criteria for all maps.

Step 10 You must synchronize network design to the mobility services engine or location server to push chokepoint information.

Removing Chokepoints from Maps

To remove an chokepoint from the map, follow these steps:

Step 1 Choose Maps > Wireless Maps > Site Maps .

Step 2 In the Maps page, choose the link that corresponds to the floor location of the chokepoint.

Step 3 From the Select a command drop-down list, choose Remove Chokepoints.

Step 4 Click Go .

Step 5 Click OK to confirm the deletion.

Editing Chokepoints

To edit a current chokepoint, follow these steps:

Step 1 Choose Configuration > Wireless Technologies > Chokepoints . The following information is displayed for each current chokepoint: MAC address, chokepoint name, entry/exit chokepoint, range, static IP address, and map location for the chokepoint.

Step 2 Click the chokepoint you want to edit in the MAC Address column.

Step 3 Edit the following parameters, as necessary:

• Name
• Entry/Exit Chokepoint—Click to enable.
• Range—Coverage range for the chokepoint.

The chokepoint range is product-specific and is supplied by the chokepoint vendor.

• Static IP Address

Step 4 Click Save .

Using Wi-Fi TDOA Receivers to Enhance Tag Location Reporting

The Wi-Fi TDOA receiver is an external system designed to receive signals transmitted from a tagged, tracked asset. These signals are then forwarded to the mobility services engine to aid in the location calculation of the asset. TDOA receivers use the method of Time Difference of Arrival (TDOA) to calculate tag location. This method uses data from a minimum of three TDOA receivers to generate a tagged asset location.

Note • If a TDOA receiver is not in use and the partner engine software is resident on the mobility service engine, then the location calculations for tags are generated using RSSI readings from access points.

• The Cisco Tag engine can calculate the tag location using the RSSI readings from access points.

Before using a TDOA receiver within the Cisco Unified Wireless Network, you must perform the following steps:

1. Have a mobility services engine active in the network. See Adding MSEs to Prime Infrastructure for details on adding a mobility services engine.

2. Add the TDOA receiver to the Prime Infrastructure database and map. See Adding Wi-Fi TDOA Receivers for details on adding the TDOA receiver to the Prime Infrastructure.

3. Activate or start the partner engine service on the MSE using the Prime Infrastructure.

4. Synchronize the Prime Infrastructure and mobility services engines. See Synchronizing Prime Infrastructure and a Mobility Services Engine for details on synchronization.

5. Set up the TDOA receiver using the AeroScout System Manager.

Adding Wi-Fi TDOA Receivers

After the Wi-Fi TDOA receiver is installed and configured by the AeroScout System Manager and the partner software is downloaded on the mobility services engine, you are ready to add the TDOA receiver to the mobility services engine database and position it on an Prime Infrastructure map.

After adding TDOA receivers to the Prime Infrastructure maps, you continue to make configuration changes to the TDOA receivers using the AeroScout System Manager application rather than the Prime Infrastructure.

For more details on configuration options, see the AeroScout Context-Aware Engine for Tags, for Cisco Mobility Services Engine User Guide at the following URL:
http://support.aeroscout.com .

To add a TDOA receiver to the Prime Infrastructure database and appropriate map, follow these steps:

Step 1 Choose Configuration > Wireless Technologies > WiFi TDOA Receivers to open the All WiFi TDOA Receivers summary page.

To view or edit current WiFi TDOA receiver details, click the MAC Address link to open the details page.

Step 2 From the Select a command drop-down list, choose Add WiFi TDOA Receivers , then click Go .

Step 3 Enter the MAC address, name and static IP address of the TDOA receiver.

Step 4 Click OK to save the TDOA receiver entry to the database.

After you add the TDOA receiver to the database, you can place the TDOA receiver on the appropriate Prime Infrastructure floor map.

A WiFi TDOA Receiver must be configured separately using the receiver vendor software.
