Hangrendtl

Hangrendtl is a fictional term used to describe an integrated planetary-scale communication and transportation framework in a science fiction setting. It links orbital relays, regional hubs, and autonomous surface carriers to enable high-capacity data exchange and synchronized movement of people and goods.

Design and operation. The Hangrendtl network is a multi-layer mesh. Core nodes provide backbone services; edge nodes manage local traffic and sensors. Routing is decentralized, with autonomous agents renegotiating paths in real time to optimize latency, energy use, and safety. Communications are encrypted with in-universe protocols, and the system supports offline operation through cached routing.

Applications. In-universe usage includes rapid freight convoys, emergency response, and citizen communications during crises. Transport ranges from automated shuttles to long-haul drones, coordinated by a unified timetable and dynamic routing.

Development and governance. The concept arose from a consortium of planetary administrations and the central council. Early pilots appeared in the late 22nd century, with broader deployment across several planets by the mid-23rd century in the story. Governance focuses on interoperability standards, security, and equitable access, though politics shape implementation.

Variants. Hangrendtl Core (backbone), Hangrendtl Relay (mid-range relays), and Hangrendtl Edge (local access points), optimized for different scales and power.
