…CERN’s new mobile operator Peter JURCSO BE-CO-IN

Why to change now? • CERN regularly re-tendering service contracts to have the “Best value for money” • Call for tender for new mobile operator was launched in 2014 after 8 years with Sunrise • Contract with new provider approved by Finance Committee in December 2014 • 4 years initial contract with optional extensions up to 16 years for mobile voice and data services

Swisscom • Improved mobile services • • New tariffs: • • • LTE (4 G) available on Swiss side UMTS (3 G) and LTE (4 G) under authorization for French side UMTS (3 G) and LTE (4 G) in the underground facilities up to 150 Mbps download speed in LHC experimental areas ~ 50% cost reduction in average Significantly cheaper data roaming New SIM cards and new numbers 5

Network migration challenges • The network must be installed while operating the current one: • • • The complexity of the network : • • • 2 G, 3 G and 4 G in all sites 14 outdoor & 37 indoor sites 17 CERN indoor sites in the LHC (REs & TI 8) Advanced services must be integrated: • • New space, fibers & power supplies required in all sites New mast/antennae for outdoor coverage Roaming control, switch board interconnection… Regulation and legal permits in two countries The new network will be ready by 1 st of June 6

Indoor and underground (54) • LHC: • • Transfer lines : • • PS, AD, LINAC 3, LINAC 4, N_TOF, CFT 3, ISR, DIRAC, ISOLDE Buildings 358, 2013, 839 Prevessin: • • 1 sites covering TI 2 and 1 CERN site covering TI 8 SPS (8 sites) Meyrin: • • • 9 sites on the surface covering the lifts and caverns 16 CERN sites in the REs covering the tunnel SCX 5 North area, building 911 SM 18 (1 site) Transmission: • Buildings 58, 513, 874 8
