REMOTE COLLABORATION AT CERNDaily work meetingsTypically involves:Meeting Rooms and desktopsAround 20 participantsFrequency:250 per day


Collaboration meetingsTypically involves:Meeting Rooms and desktopsAround 100-250 participantsFrequency:Around 2-4 per month



Outreach events (masterclasses, virtual visits)Typically involves:Meeting RoomsAround 10 participantsFrequency:Around 1 per week

Remote Operation CentersTypically involves:Rooms24/7 connection of all institutes involved in control and monitoring


Remote Teaching2 dedicated rooms11USE CASES

Job interviewsTypically involves:DesktopsPoint 2 point discussionsTypically involves:DesktopsReplaces chat or phone
