5G from Space: How Constellation Is Connecting the Disconnected
5G from Space: How Constellation Is Connecting the Disconnected
What if you could stream Netflix from the middle of the Sahara—thanks to 5G from space? In this episode, we explore the bold vision of Constellation Technologies, a Paris-based startup building a low-orbit satellite network to deliver fiber-like 5G speeds anywhere on Earth.
Founded by former World Black engineer Charles Delfieux, Constellation is launching tiny satellites in very low Earth orbit (VLEO) to bring fast, reliable, and sustainable internet to remote villages, ships, farms, and more. Their satellites offer speeds up to 150 Mbps down, 50 Mbps up, and under 30ms latency—all while reducing space junk and using recycled 5G components to cut costs.
What’s revolutionary is their telco-friendly model: instead of competing with telecom giants, Constellation partners with them—offering bandwidth and terminals that carriers like Orange or AT&T can resell, turning space into an extension of existing networks.
Tune in to hear how this sci-fi sounding mission is becoming a reality, and why space might just be the key to true global connectivity.
