Threats and opportunities in the digital chaos

Data vs. Energy

La Tribune

Cloud and 5G are Military

Les Echos

How to Attack A Country...

  • Cut submarine cables happened
  • Shutdown 4G/5G core network happened
  • Shutdown OSS/BSS of cloud happened
  • Shutdown BPG routing mastered
  • Spread Windows virus happened
  • Destroy DC with fire happened
  • Destroy DC with graphite bombs mastered
  • etc.

How can we achieve digital resiliency...

  • Supplier
    • Made in USA (like F-35) → not enough (like Ukraine)
    • Made by Myself
  • Architecture
    • Centralized
    • Decentralized → edge computing, distributed core network 
  • Software
    • Foreign proprietary
    • Open Source or Licensed Source
  • Hardware
    • Single supplier dependency
    • Portable, compact and low energy

Why SimpleRAN?

  • 100% software
  • Works on all CPUs (Intel, AMD, ARM, Hygon, etc.)
  • No hardware accelerator needed
  • Efficient: 4T4R 100 MHz with 4 cores
  • Stable: deployed on public networks
  • Integrated: from PHY to core network
  • Compact: gNodeB/5G size is a few MB
  • Complete: built-in carrier grade OSS/BSS
  • Edge native: CDN, IoT buffering, etc.
  • Sovereign: open source / source code license
