The LocURa4IoT testbed comprises 64 nodes spread over 3 sites (plateaux, in french): P1, P2 and P3.

| P1: offices and open-space | P2: appartment | P3: anechoic chamber |
On all sites, node deployments have been conducted using laser rangefinders. Regular verification indicate a precision under 2~cm for the fixed positions. Therefore, the real position of each node, fixed or mobile, can be used in the results to compute a ranging/localization error.
In view of the layout of the walls on the different sites, some radio links are NLOS (Non Line-of-Sight).
Example of typical usage for each site:
- Site P3 can be used for initial evaluation of a protocol in an isolated environment.
- The implementation is then tested on site P1 with a larger number of nodes in a more challenging environment.
- In some cases, the solution can also evaluated through its usage: this is done on site P2 and involves human-machine interactions.
