Technical expertise

We provide solutions to the questions of overall system contractors as well as equipment manufacturers:

How can the system be optimised? Which enhancements should be prioritised?

Why doesn’t the system as-is work properly?

Will the system as it is currently specified work? What will be its performances and its dependability? How can it be operated?

Notable missions carried out by COGISYS

Mobile network operator

Disaster recovery study for a cellular operator
Know more
  • We performed a comprehensive survey of network elements vulnerable to failures or accidents (transmissions in the core network and for the backhaul of base stations, switching system, voice-mail and SMS servers, network operations centre)
  • 15 000 base stations, 30 major switching sites
  • We recommended solutions to do away with the most critical points of vulnerability, and an action plan to implement these solutions

Industrial prime contractor in satellite communications

Optimisation of the performances of a network based on 80 LEO satellites
Know more
  • We designed the user-network protocol
  • We optimised network capacity

Industrial prime contractor in fixed communications

Study of the introduction of the DWDM technology in a WAN with national coverage
Know more
  • We analysed the state of the art for DWDM equipment, including its monitoring and control (RFTS solution)
  • We analysed network specifics (information security, interface between the transmission and network layers, monitoring)
  • We drew up recommendations for DWDM engineering

Industrial prime contractor in information systems

Information Systems Security
Know more
  • We provided expert advice on the specification of a Public Key Infrastructure (PKI) in preparation of its accreditation
  • We designed its security architecture and its interfaces
