About wireless location
Wireless location tracks 802.11 devices for medical monitoring, asset management, and logistics management.
Wireless location system
As shown in Figure 1, a wireless location system contains 802.11 devices, information receivers(802.11 APs), and a location server. 802.11 devices include Tags (small wireless devices that can only send 802.11 packets periodically) and MUs (all 802.11 devices except Tags).
Figure 1 Wireless location system
Wireless location mechanism
Wireless location operates as follows:
1. The 802.11 devicesends a wireless packet.
2. Upon receiving the wireless packet, the APs encapsulate the collected location information (including RSSI and timestamp) in location packets, and then send the packets to the location server.
3. The location server calculates the location of the 802.11 or BLE device.
A location server needs location information from a minimum of three APs to locate an 802.11 or BLE device.
Wireless location methods
RF fingerprinting sets up a fingerprint database by collecting signal strength and location of clients. To locate a client, an AP encapsulates the location information of the client into a location packet and sends the packet to the location server. The location server uses a location algorithm to match the signal strength of the client against information in the database to locate the client.
RF fingerprinting is used to locate MUs and Tags.
Restrictions and guidelines: Wireless location configuration
You can configure APs by using the following methods:
· Configure APs one by one in AP view.
· Assign APs to an AP group and configure the AP group in AP group view.
· Configure all APs in global configuration view.
For an AP, the settings made in these views for the same parameter take effect in descending order of AP view, AP group view, and global configuration view.

Configuring wireless location common parameters
Configuring packet dilution
About packet dilution
This feature enables an AP to send a location packet upon receiving the specific number of wireless packets or at the specified interval. This reduces the workloads of the location server and the AP.
For example, the dilution factor is 10 and the timeout timer is 5 seconds. If RF fingerprinting is enabled, the AP sends a location packet every time it receives 10 wireless packets from an MU client (excluding management and broadcast packets). If the AP fails to receive 10 packets from an MU client before the timeout timer expires, it sends the most recent wireless packet to the location server.
Restrictions and guidelines
This feature takes effect only on MU clients for RF fingerprinting.
Procedure
1. Enter system view.
system-view
2. Enter AP view, AP group view, or global configuration view.
