Toulouse

The Toulouse site is part of the LocURa4IoT testbed. The nodes are located at IUT Blagnac (IRIT/UT2J). They are spread across offices and demonstration room on the first floor of building C. This site focuses on Ultra-Wide Band (UWB) technology and is catered towards indoor localisation, but can also host experiments on other available technologies such as BLE and other topics such as time synchronisation .

Topology

Toulouse testbed is deployed at a building scale, over the first floor of building C of IUT Blagnac.

  • The nodes are currently a mix of Qorvo’s DWM1001 and Qorvo’s DWM3001.
  • Most of the nodes are fixed at a height of 2.65m and at least 30cm away from the walls and ceilings on dedicated plastic mounts.
  • Some nodes are located on the floor or at an intermediate height (1,65m) to enable 3D localisation experiments.
  • 8 nodes (dwm1001-{97,98,99,100}.toulouse.iot-lab.info and dwm3001-{97,98,99,100}.toulouse.iot-lab.info) are located in an anechoic chamber. Their position and the setup of the anechoic chamber is subject to change without notice due to local experiments.
  • The walls are either load-bearing bricks walls, wood pannel walls or drywalls.
  • Node positions are estimated to be known within 2cm of precision [Bossche2022].
    • Note : a 3D LIDAR scan with sub-cm accuracy is scheduled. This page will be updated once this is done.
  • The node positions are available as a JSON file here.
  • Nodes dwm1001-60 and dwm3001-23 are on a motorised rail, hence their position are not fixed. Their positions are published live on IoT-LAB’s MQTT broker, on the topic localisation/toulouse/<node-id>/mobile
