TETRA (CERN’s Safety Radio Communication Network) Speaker : Frédéric CHAPRON IT-CS Tetra forum 7th of February 2013

Why TETRA ? Replacement of the old VHF network of the Fire Brigade because of many weaknesses Remember that the GSM network is NOT a safety network TETRA stands for Terrestrial Trunked Radio Digital technology designed for safety group communications Widely used in the world to ensure critical communications for police, rescue organizations, army, etc… TETRA is a standard of the European Telecom Standard Institute Frédéric Chapron IT-CS Tetra Forum 7th of February 2013

Objectives of the project A fully-secured radio network Reliability, high availability, and resiliency Cover all indoor CERN sites and CERN surroundings on surface Always guarantee communications for the fire brigade Enable Swiss and French fire brigades to use their own radios in CERN underground facilities Be ready to manage the higher risk of safety incidents during LS1 Many co-activities & Many people Bring new features for the needs of the Fire Brigade and CERN Develop an indoor localization system coupled with a man-down feature to serve a lone worker protect mechanism under certain circumstances Frédéric Chapron IT-CS Tetra Forum 7th of February 2013

Fire Brigade Dispatcher Objectives of the project Integrate in the network other user communities (security/CSA, transport, experiments, maintenance teams…) Contrôle room EXCR Fire Brigade Dispatcher One group of communication Intervention Area Fireman CSA Fireman Electrical piquet Frédéric Chapron IT-CS Tetra Forum 7th of February 2013

Remember The TETRA network is a safety network made first for the fire brigade and also for YOU. It allows the CERN fire brigade to intervene faster in case of incident Allow easy cooperation between CERN’s safety and security players: Typically this is the right network to guarantee communications during an event like the Open Days Frédéric Chapron IT-CS Tetra Forum 7th of February 2013
