Grenoble

On the Grenoble site, the nodes are deployed at Inria Grenoble – Rhône-Alpes. They are spread across corridors of the the ground floor. This site is very popular for large network and multi-hop experimentations.

Topology

Grenoble testbed is deployed at a building scale, over the ground floor of Inria building, through corridors in the raised floors and dropped ceilings.

• The nodes in the raised floors are fixed horizontally under the tiles.
• The nodes in the dropped ceilings are fixed vertically to the wall at a height of 2.6 m and 3.2 m.

We have also added an extension with a room (i.e. K on the plan) to plug in the new boards and manage LoRa deployment with a The Things Network gateway.

Here is the distribution of nodes:

• J corridor
  • floor: m3-[1-69]
  • ceiling: m3-[359-380], a8-[1-58]
• F1 corridor:
  • floor: m3-[70-94]
  • ceiling: a8-[59-77]
• F2 corridor:
  • floor: m3-[95-178]
• F3 corridor:
  • floor: m3-[179-205]
  • ceiling: a8-[78-94]
• F4 corridor:
  • floor: m3-[206-289]
  • ceiling: a8-[95-148]
• G corridor:
  • floor: m3-[290-358]
  • ceiling: a8-[149-228]
• K room:
  • nucleo-wl55jc-[1-5]
  • samr34-[1-2]
  • rpi3-[1-5]

See the video and photos below to visit the deployment across the building.

GPS

Some IoT-LAB A8-M3 boards deployed in Grenoble are equipped with a GPS chip. It allows to synchronize precisely data collection from these nodes together. They are located near the GPS antenna repeater at the corner of corridor J and F.

Here is the list of these 32 nodes:

• a8-1, a8-3, a8-4, a8-8,
• a8-10, a8-11, a8-13, a8-15,
• a8-16, a8-19, a8-20, a8-59,
• a8-61, a8-63, a8-65, a8-68,
• a8-70, a8-129, a8-130, a8-131,
• a8-132, a8-134, a8-135, a8-136,
• a8-137, a8-138, a8-139, a8-142,
• a8-143, a8-144, a8-147, a8-148
