As shown in Figure 1, a wireless location system contains 802.11 or BLE devices, information receivers (802.11 or BLE 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 or BLE device sends 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

H3C WLAN devices support the following location methods:

· AeroScout—Used to locate MUs and Tags.

· RF fingerprinting—Used to locate MUs and Tags.

· RTT—Used to locate MUs.

· BLE—Used to locate BLE-capable devices.

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.

RTT

RTT location is an H3C-proprietary location method. It uses the round-trip time (RTT) to locate MUs, including associated and unassociated clients. RTT location is more accurate than RSSI-based location because it is more immune to interference, multipath effect, deployment density, and environment changes.

The location server selects a group of location APs for each associated client based on the client list reports and then sends a location request to each AP. The AP then locates the clients in the client list contained in the location request.

To locate an associated client, the AP sends a measurement packet to the client. Upon receiving a response, the AP encapsulates the information (including the sending time and receiving time) into a location packet, and then sends the location packet to the location server. The location server uses the information to calculate the location of the client.

For an AP to locate unassociated clients, enable unassociated client location for the AP. For more information about unassociated client location, see "Configuring unassociated client location."

BLE

BLE location is applicable only to IoT APs that support BLE. For more information about IoT APs, see Internet of Things Configuration Guide.

BLE location can locate the following devices:

· iBeacon devices.

iBeacon devices are devices that use the iBeacon protocol developed by Apple Inc.. When an AP receives an advertisement from an iBeacon device, it adds the device to the neighbor list and periodically sends neighbor list reports to the location server. The neighbor list contains the UUID, major ID, minor ID, and the most recently collected transmit power and RSSI of iBeacon devices.

You can manage iBeacon devices on the location server and view the iBeacon device information including battery capacity and RSSI through graphs, charts, or reports.

· BLE devices that conform to the H3C-defined standard.

When an AP receives an advertisement from a BLE device, it immediately sends the advertisement information to the location server for further calculation.

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.

About this task

Upon receiving a wireless location packet, an AP adds an absolute timestamp or a relative timestamp to the location packet. An absolute timestamp represents the time elapsed since 1970. A relative timestamp represents the time elapsed since the AP started.

Managing iBeacon devices

About this task

The location server manages iBeacon devices as follows:

1. When an AP receives an advertisement from an iBeacon device, it adds the device to the neighbor list and periodically sends neighbor list reports to the location server.

2. The location server issues iBeacon device configurations to the AP.

3. The AP verifies the default password or the specified password with an iBeacon device and deploys configuration to the device only when password verification is successful.

If an AP does not receive any packets from an iBeacon device within the aging time, the AP performs the following actions:

· Removes the device from the neighbor list.

· Notifies the location server of the device removal event.

You can modify the password for an iBeacon device on the location server. After modification, the AP sends the new password to the iBeacon device and saves the password. Then, they use the new password for verification.

Restrictions and guidelines

You must specify the default password for deploying configuration to iBeacon devices. This password must be the same as the factory password of the iBeacon devices.

Procedure

1. Enter system view.

system-view

2. Enter AP view, AP group view, or global configuration view.

Locating BLE devices

About this task

When an AP receives an advertisement from a BLE device with the specified manufacturer prefix, the AP sends the device information to the location server at the specified interval.

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. Packet dilution operates as follows:

· 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.

· If RTT location is enabled, the AP performs a location measurement every time it receives 10 probe requests from an unassociated client. If the AP fails to receive 10 probe requests from an unassociated client before the timeout timer expires, it performs a location measurement when the timer expires.

Restrictions and guidelines

This feature takes effect only on MU clients for static AeroScout location or RF fingerprinting and unassociated clients for RTT location.
