2. System Overview (Unit Network, Home Units, IMS, Customs Gate) 

The system treats the pipe segment between utility poles as the basic unit and transports standardized spherical packets electromagnetically. It consists of (i) a utility-pole unit network, (ii) home units that act like household mailboxes, (iii) an Inspection & Maintenance Station (IMS) responsible for inspection, cleaning, isolation, collection, and repositioning, and (iv) an optional Customs Gate Unit (CGU) for cross-border delivery.



Figure 1. Overall architecture (concept). Home units and IMS connect to the utility-pole unit network; CGU is used only when cross-border routing is required. 

In this document, a '30 m unit' refers to a structural unit spanning roughly 30 meters between utility poles. The 30 m value is illustrative and can be adjusted based on local conditions and construction constraints. By modularizing into units, the structure, contracts, maintenance, and investment units become explicit, simplifying expansion, replacement, and settlement.



Figure 2. Minimum interface for a 30 m unit (concept): bidirectional endpoints and at least one branch. In principle, the node degree should be at least 3.
