-- A cellular device for local development, reproducing a real field capture.
--
-- The fleet this platform is developed against contains no LTE hardware at all
-- (49 ethernet interfaces, 7 wifi, zero cellular), which is exactly the position
-- CAPsMAN support was written from before two bugs shipped. This seeds the shape
-- of a real modem so the LTE paths can be exercised against actual endpoints.
--
-- Values come from a MikroTik ATL 18 (Quectel EG18-EA, Cat-18) on VIVACOM,
-- contributed by @trackersoft in discussion #85. See
-- backend/src/utils/__tests__/fixtures/lte-atl18.md for the raw capture.
--
-- What makes this shape worth reproducing:
--
--   * RSRP −97 dBm — "fair" on its own — on a link running 256QAM at CQI 15 with
--     two spatial streams, which is the modem at its ceiling. Any UI that grades
--     on RSRP alone gets this device visibly wrong.
--   * a primary carrier plus an aggregated one, so carrier-aggregation rendering
--     is exercised rather than assumed
--   * a configured band allow-list (1,3,7) that is wider than the bands actually
--     observed, which is the state a band-lock warning has to reason about
--   * tower movement history, which cannot be recovered after the fact
--
-- Everything is prefixed `fixture-` and removed by seed-lte-fixture-clean.sql.
