Synopsis:
GPS doesn´t work properly inside buildings. Indoor positioning systems are a growing market for developing new services. Wireless positioning systems are based on measuring properties of the received RF signal at the receiver: Angle of Arrival (AoA), Time of Arrival (ToA), and Received Signal Strength (RSS). The fingerprint technique uses RSS and is the most spread because of its simplicity, it adapts well to no line of sight and complex channel indoor conditions. We will explain key concepts of the fingerprint systems and work in progress of a RSS Monopulse Direction of Arrival System for WiFi Positioning and a Bluetooth Low Energy positioning system with leaky wave antennas.
