Telecoms and IT: networks, data centres and systems
4G and 5G mobile networks, fibre, subsea cables, data centres and industrial networks: we deploy the engineers who build and secure digital infrastructure.
Our approach
Digital infrastructure, from mast to data centre
Telecom and IT projects share the constraints of energy projects: many sites, tight schedules, and interfaces between civil works, power and systems. CELESTAL supports operators, vendors, integrators and industrial groups on the design, rollout, integration and security of their networks, in France, the Middle East and Asia.
What we do
- Mobile networks: 4G and 5G rollout, radio engineering, drive testing and optimisation.
- Fibre optics: FTTH, backhaul and backbone networks, acceptance testing.
- Subsea cables: project management, marine campaigns, landing stations.
- Data centres: power, cooling, commissioning and operations.
- Industrial & rail networks: OT, SCADA, GSM-R and FRMCS, cybersecurity.
- IT infrastructure: enterprise networks, cloud, migration, support.
