Over the last two decades we have witnessed a constant development of wireless communication technologies.

Mobile telephony networks, Internet access points, point-to-point communications are all sources of wireless networks based on communication standards defined by different organizations (ETSI, CEPT, IEEE, FCC). Each of these standards is allocated a frequency band associated with several channels each having a maximum amount of energy.

In order to obtain a frequency and temporal image of these wireless networks, the CARERC project proposes a software and hardware infrastructure creation for measurement,  in order to carry out a dynamic 3D electromagnetic mapping of a given space based on the exploitation of sensor networks.

In order to be able to operate in any type of environment, this network must be autonomous in energy. This autonomy passes by softwares (optimization of communications and the activity of network elements) and hardwares (energy harvesting from different sources : electromagnetic waves, solar…).
