Connection Without Cables
The Architecture of Network Mobility
The Untethered Reality
The Network built a planetary nervous system, but it was anchored by glass and copper. This realm breaks the physical tether. By combining radio propagation, cellular frequency reuse, and dynamic routing, the connection no longer belongs to the building—it follows the human.
