Location tracking with radbeacon Bluetooth#

One of those variables is the received signal strength indicator (RSSI), which may give an estimate of the flight distance of the signal from the beacon to the receiver. Moreover, BLE technology provides the variables that can be used to predict the position information.

Location tracking with radbeacon Bluetooth#

However, this new feature in Bluetooth technology made it a good candidate as part of positioning systems as it provides an efficient way of transferring messages with low energy, with the help battery-powered mobile beacons to emit messages for durations in the order of years. It has been introduced to facilitate short-range communication, which requires large amounts of data transfer.

We attempt to model and solve this issue using probabilistic methods.īLE is a distinctive feature that was added to the Bluetooth technology standard at v4.0. As the underlying technology uses short wavelength radio signals, data transfer is affected by a high number of factors, such as scattering and reflections, all of which can not be exactly known. In the most general setup, we distribute beacons whose exact positions are not necessarily known in a closed indoor area, and we need to estimate and track the position of a mobile sensor using BLE messages emitted by the beacons. In this work we address the problem of positioning and tracking using beacons that transmit data with Bluetooth low-energy (BLE) messages.
