What it does

RF propagation modeling using electromagnetic operators. Free-space path loss, atmospheric absorption, and multipath fading computed from first principles.

Signature

Request

POST /api/telecom/propagation

Param	Type	Required	Default	Description

Integrate

1. Domain solver — compose with KO42 + two additional operators from the matching family for pulse-coherent results.
2. Digital twin — pipe sensor data into this protocol every Zeqond to keep the model phase-locked with the system.
3. Alert threshold — flag results whose error_pct exceeds 0.1% as out-of-spec events for the operations layer.

Seeds

• Near — wrap /api/telecom/propagation in a language SDK so builders can call it in three lines.
• Medium — publish a reference integration demonstrating ZeqPropagation — RF Path Loss alongside a real workload, with pulse-aligned metrics.
• Far — propose ZeqPropagation — RF Path Loss as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.
