Within the framework of distance working, several communication tools by videoconference and instantaneous communication are proposed.

At the service of students, researchers, teachers and staff of the Education-Research community, RENATER offers a highly reliable and secure network, facilitating collaboration and convergence of scientific and academic projects at the national level but also at the European and international levels.



The RENAvisio service is available to all establishments connected to RENATER:

  • Access to the reservation portal is via the federation of identities education-research.
  • Reservation is not possible for members of an institution identified as students.
  • The connection to a videoconference is done without authentication.

In order to organize and book meetings, authenticate yourself on http://renavisio.renater.fr. Once authenticated, you will be able to:

  • schedule a new meeting
  • manage your meetings (modification, deletion)
  • organize a RENAvisio+ (HD) meeting if you are a visio correspondent of an institution
