Licensing Requirements and Limitations for Bluetooth Location

Involved Network Elements

APs mentioned in this document are Huawei AP products. You are advised to use Huawei APs to connect to the AC.
You can run the display ap-type all command to check the default AP types supported by the device.

Bluetooth device

Bluetooth devices generate Bluetooth signals based on the BLE or iBeacon protocol. They include BLE devices, Bluetooth tags, and Bluetooth clients (such as Bluetooth thermometers, blood pressure monitors, and heart rate monitors).
- BLE devices are manufactured by BLE device vendors and generate Bluetooth signals based on the iBeacon protocol. BLE devices periodically send BLE broadcast frames.
- Bluetooth tags are manufactured by Bluetooth tag vendors and generate Bluetooth signals based on the BLE protocol. Bluetooth tags periodically send BLE broadcast frames.
- Bluetooth clients are manufactured by Bluetooth client vendors and generate Bluetooth signals based on the BLE protocol. Bluetooth clients periodically send BLE broadcast frames.

Location server

The location server computes the signal transmission model according to locations of APs and obstacles, and calculates locations of terminals, rogue APs, or Wi-Fi interference sources based on the RSSI information collected by each AP. It draws maps and displays locations of the devices on the map.

Licensing Requirements

When the device is used as a WLAN AC, the number of online APs supported by the device is controlled by licenses. The device supports a maximum of 16 online APs. To increase the number of online APs supported by the device, apply for and purchase a license from the agent.

AP resource license-1AP for WLAN access controller
AP resource license-16AP for WLAN access controller
AP resource license-32AP for WLAN access controller
AP resource license-64AP for WLAN access controller
AP resource license-128AP for WLAN access controller
AP resource license-512AP for WLAN access controller

For details about how to apply for a license, see Obtaining Licenses in the S1720, S5700, and S6700 Series Switches License Usage Guide.

Feature Support in V200R019C10

This feature is supported only by the following models: S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-HI, S6730S-H, and S6730-H.

Feature Limitations

Bluetooth Terminal Location

Only the AP2050DN-E, AP2051DN-E, AP4050DN-E, AP4051TN, AP6052DN, AP7050DE, AP7052DE, AP7052DN, AP4050DE-M, AP4050DE-M-S, AP4050DE-B-S, AP7060DN, AP7152DN, AP8050DN, AP8050DN-S, AP8050TN-HD, AP8082DN, AP8150DN, AP8182DN, R250D-E, and R251D-E support Bluetooth functions.
Bluetooth terminals must support BLE 4.0 or later versions and can properly report received RSSI information to the location server through apps.
After the Bluetooth monitoring function is enabled, APs will obtain battery power information about surrounding BLE devices at 02:00 of the AC system time, which is off-peak hours of WLAN services. If the system time is different from the actual time, obtaining battery power information may interrupt WLAN services. To prevent such an issue, configure the system time correctly on the AC.
After enabling the Bluetooth location function, you are advised to deploy APs in channels 1, 6, and 11 on the 2.4 GHz frequency band.

Bluetooth Tag Location and Bluetooth data transparent transmission

To implement Bluetooth tag location and Bluetooth data transparent transmission, Bluetooth devices must support BLE 4.0 or later versions and can report RSSIs to a location server through APs.
After the Bluetooth tag location function is enabled, at least three APs need to collect location information about a Bluetooth tag to be located and send the information to the location server. The location server matches the RSSIs received by the APs with information in the database, and obtains the location of the Bluetooth tag.
After enabling the Bluetooth location function, you are advised to deploy APs in channels 1, 6, and 11 on the 2.4 GHz frequency band.
Enabling both the Bluetooth scanning and broadcast functions of an AP affects the efficiency for the AP's Bluetooth module to scan surrounding BLE devices. When an AP does not serve as a Bluetooth base station, it is recommended that the broadcast function of the AP be disabled.
