# route-comms-link

`station__comms-systems__route-comms-link` · external (needs EXECUTION_BACKEND_URL configured) · domain `comms-systems` · pv-relevance `non-pv`

Route communication to optimal link based on range, data rate, criticality, and link availability. 7 link types: BLE (controller), Wi-Fi 6E (ground station), 5G (cloud), LoRa (telemetry fallback), Iridium Certus (satcom), VHF radio (ATC), ADS-B Out (position broadcast).

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
