Abstract

The beacons help in the micro-locationing of the mobile device. By analyzing the physical location of a mobile device over time, the beacon server can predict the direction in which the mobile device is moving. This information is sent to the Wi-Fi APs and also to the application running in the mobile device to have an improved user experience on the Wi-Fi network.

Method to Improve WiFi Client Roaming and Session Migration with the Help of BLE Beacons

In a Wi-Fi network infrastructure with multiple access points (APs), services provided by Bluetooth Low Energy (BLE) beacon devices (or Beacons) present in the same environment can be used to provide a better Wi-Fi user experience. Two such improvements are listed down in this document.

The infrastructure consists of the following:

1. Wi-Fi APs servicing multiple Wi-Fi mobile devices. The APs may also have an in-built Bluetooth module that can help the APs discover Bluetooth devices in their vicinities.

2. Beacons announcing periodic identity messages that help in micro-locationing of Bluetooth enabled client devices.

3. A beacon server with a map of all Beacons and their physical location. The beacon server also has the map of Wi-Fi APs and their physical locations. Thus the beacon server knows which Beacons are located within the Wi-Fi radio coverage area of each AP.

4. Mobile devices connected to the Wi-Fi network. An application that runs on each of them can be capable of receiving the Bluetooth messages from the beacons and then forwarding it to the beacon server using the Wi-Fi connection.

The beacons help in the micro-locationing of the mobile device. By analyzing the physical location of a mobile device over time, the beacon server can predict the direction in which the mobile device is moving. This information is sent to the Wi-Fi APs and also to the application running in the mobile device to have an improved user experience on the Wi-Fi network.

When a mobile device moves from the coverage area of one AP to the coverage area of another AP, it is called a roam trigger event. This event can be detected in two different ways:

Roam Trigger Event detected by Beacon Server.

When a mobile device moves along across various beacons, the beacon server detects that the mobile device has moved from a beacon located in the coverage area of one AP to a beacon located in the coverage area of a second AP, it detects that as a roam trigger event.
