UMR CNRS 6164
With more than 250 staff in research laboratories at INSA-Rennes, the University of Rennes 1 and Supélec Rennes, IETR offers a high level of expertise to the industrial and scientific communities.
In complement to its scientific capabilities, IETR has the following technical facilities at its disposal: several anechoic chambers (SER, millimetre-band, near-field), a reverberant chamber, an experimental station for radar systems, a clean room for applications in microelectronics, etc.
