Indoor positioning using Bluetooth LE.

Introduction

The Internet of Things (IoT) is believed to connect tens of billion devices by the year 2020 making it one of the key drivers for the semi-conductor industry. Thereby, a major part of the IoT will consist of moving devices such as unmanned cars or drones. For these kinds of applications the knowledge of the current location is essential.

Solely relying on Global Navigation Satellite Systems (GNSS) such as GPS is insufficient, since these signals cannot be received indoors. Even though there is no well established technology yet, Bluetooth LE beacons are gaining interest as low cost solutions for indoor positioning.


Project Description

The goal of this project is to implement the digital baseband of a Bluetooth LE receiver, that is able to gather information about nearby Bluetooth beacons. It should be able to detect their identity and received signal strength, which can then be used to determine the position of the IoT device. This baseband can then be integrated on our RF SoC.
