Communication Systems

The Communication Systems Group is responsible for CERN-wide networking, telephony and radio services. These include

  • the site-wide campus network, including Wi-Fi coverage and support for eduroam,
  • the high-performance data centre network and high-bandwidth connections to the worldwide physics community,
  • the dedicated technical network supporting accelerator operations and control networks for experiments,
  • the CERN Internet eXchange Point, CIXP,
  • CERN’s fixed and mobile telephony services including the CERNphone clients,
  • the TETRA digital radio service for the Fire Brigade and site guards, and
  • support for IoT devices including a LoRaWAN infrastructure.

Communication Tools (IT-CS-CT)

Section Leader: Marwan Khelif

The Communication Tools section develops and maintains the software tools that underpin the operation of CERN’s network and telephony services, most notably the central networking database, LanDB, and the network portal that allows users to register their networking devices.

Deployment & Operations (IT-CS-DO)

Section Leader: John Shade

The Deployment and Operations section is responsible for the day-to-day operation of CERN’s networking and telecommunications infrastructure, responding to user queries and intervening to address any temporary problems. The section also deploys new infrastructure as necessary to support CERN’s needs, for example the extension of the network and telephony infrastructure to the newly constructed HL-LHC tunnels.

Network Engineering (IT-CS-NE)

Section Leader: David Gutierrez Rueda

The Communication Engineering section is responsible for the planning, deployment and operation of CERN’s internal networking infrastructures---the sitewide campus network and Wi-fi infrastructure, the data centre network, CERN’s external network connections, the high-speed links to the LHC and other experiments, control networks for the experiments and the dedicated technical network that supports accelerator operations. The section also supports the many essential network services such as DNS, DHCP, NTP, eduroam and the firewall.

Telecoms & Radio (IT-CS-TR)

Section Leader: Rodrigo Sierra Moral

The Telephony and Radio section supports CERN’s fixed-line and mobile telephony services, the TETRA digital radio service for the Fire Brigade and the LoRaWAN infrastructure to support low power IoT devices. The section is also responsible for the development and maintenance of the CERNphone softphone client for Windows, MacOS and Linux deskops/laptops as well as Android and iOS mobile phones.
