Talk paths

TOWER: Internet / cloud when available
SITE: Same-site LAN
RADIO: Same Wi‑Fi, no broker
MESH: Same Wi‑Fi relay, max 4 hops — in code; field day not yet run

Mesh only extends talk on phones that already share the same Wi‑Fi. Layer 2 (boot as radio from a system image) is packed in the repo, not flashed on a phone yet.

Company

PTT Field Communication Company builds RADIO OS for crews who already carry phones and still need push-to-talk when the tower path is weak.
