Configuring wireless location
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
AeroScout
AeroScout location is used to locate Tags and MUs by using signal strength triangulation. Signal strength triangulation determines the location of a client by triangulating the relative signal strength detected by a minimum of three APs in the WLAN.
RF fingerprinting
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.

Specifying the AeroScout location mode
About this task
AeroScout location provides the following location modes:
· Dynamic location—An AP negotiates with the location server to obtain the multicast MAC address for Tags, packet dilution attributes, and the IP address and port number of the location server. The location server obtains the AP's AeroScout version, MAC address, radio mode, and channel information. Then the location server notifies the AP to send location packets.
· Static location—An AP gets predefined location attributes from the AC and then starts to send location packets to the location server. Use static AeroScout location if the location server does not support dynamic negotiation with an AP.
In dynamic AeroScout location, an AP saves the IP address and port number of the location server in the flash memory. It uses the information to report its IP change or reboot events so that the server can respond in time. The AP maintains such information as follows:
· The AP starts a 10-minute timer after receiving a set configuration message that contains the server information. If it receives another set configuration message within 10 minutes, the AP only updates the configuration information in the cache. When the timer expires, the AP saves the information in the flash memory.
· If an IP change or reboot event occurs within 10 minutes after the AP receives the first configuration message, no server information is saved in the flash memory. The AP does not send an IP change or reboot message to the location server.

Configuring wireless location common parameters
Configuring packet dilution
About this task
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 AeroScout location or 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.

Configuring location packet rate limiting
About this task
This feature enables an AP to discard excessive location packets when both the CIR and CBS are exceeded. This practice prevents location packets from flooding the location server.
Restrictions and guidelines
This feature takes effect only when AeroScout location or RF fingerprinting is configured.
Procedure
1. Enter system view.

¡ In global configuration view, the CIR and CBS for location packets are not set.
Configuring wireless location keepalive
About this task
This feature enables an AP to send Hello packets to the location server at an interval of 15 seconds. If the location server does not receive any packets from an AP within 30 seconds, the location server determines that the AP is offline.
Restrictions and guidelines
This feature takes effect only when RF fingerprinting is configured.
Disable this feature to avoid bandwidth waste if the location server cannot process Hello packets.
Procedure
1. Enter system view.
system-view
2. Enter AP view, AP group view, or global configuration view.
¡ Enter AP view.
wlan ap ap-name
¡ Enter AP group view.
wlan ap-group group-name
¡ Enter global configuration view.
