6G White Paper (Pt. 10): Cell-Free Massive MIMO Communications

Substack Post Link /w Downloads || Imgur Album Section XIn 5G, you connect to a tower. In 6G, the network surrounds you. In Part 10 of our 6G White Paper Breakdown, we cover Section 10: Cell-Free Massive MIMO. This isn't just an upgrade; it's a total architectural shift from "Cell-Centric" to "User-Centric" networks.We explain how 6G plans to replace distant cell towers with thousands of "Access Points" (up to 1,000 per square kilometer) that work together to serve a single user. We break down the engineering terms—like Favorable Propagation and Channel State Information (CSI)—and explore the darker implications of a network that offers "no hiding place," effectively creating a "biometric lock" around the user.Key Concepts Covered:Cell-Free Massive MIMO: The shift from cell towers to a distributed "swarm" of antennas.User-Centric Architecture: The signal follows the target rather than covering a zone.The "Sniper's Corridor": How "Favorable Propagation" ensures the signal always finds a direct path to you.
