A location dot has never settled a freight claim. Condition evidence, custody proof, audit-ready exports — those are hardware decisions, not software features. eelinktech.com/evidence-grad…

Resilience isn’t a backup slide—it’s an operable capability. We’re sharing a dual‑base parallel NPI framework for global hardware delivery certainty: • Cross‑site capacity rebalancing • Parallel EVT→DVT→PVT (no skipped checks) • Fulfillment network design Compliance‑first.

NB‑IoT vs LTE‑M for tracking: NB‑IoT = deep coverage, small/infrequent messages (often stationary use) LTE‑M = mobility higher throughput (better for moving assets) Battery life = wake transmit cadence

“Where’s Trailer #27?” shouldn’t take 20 minutes. LTE‑M on the trailer BLE yard zones → last seen zone/dock timeline. Stop searching. Start dispatching. Reply “PILOT” for a checklist.

Dry containers still travel “dark.” Our new 30s demo shows a GPS e‑seal that detects door‑open/tamper, runs store‑and‑forward through coverage gaps, and publishes replayable events to your platform via MQTT/REST. Evidence > assumptions. #DryContainer #IoT #NBIoT #LTEM

Network down? No problem. 📶🚫 Watch how EELINK sensors handle cold chain monitoring offline. Data is queued, signed, and auto-synced as a secure Webhook payload the moment connection returns. Context matters: Door Open Temp Drift captured instantly. 🚛❄️#IoT #ColdChain #EELINK

📍Trailer crosses a geofence → evidence-grade event (timestamp GNSS motion). Logged locally, delivered as a clean payload into YOUR platform. No proprietary SaaS, no lock-in app. Reply "TRAILER" for a 48-hour field trial checklist. #IoT #AssetTracking #Geofence #LTEM #NBIoT

Never lose a data point to a dead zone. Our edge-sync strategy uses ring-buffer store-and-forward to bridge coverage gaps. Once back online, it bursts signed telemetry with zero data loss. Optimized for battery life via thresholded wake. Currently hitting 168h endurance in PVT.

Ultra-low-power isn’t a “feature toggle.” It’s dozens of architecture firmware test decisions that must bring you back to a true low baseline after every wake. The waveform doesn’t care about slideware. Optional hashtags: #IoT #Embedded #Hardware

Eelink devices → TCP for reliability *or* UDP for efficiency. Flip to UDP when assets sleep: same payload, 0 keep-alives, weeks of data on a few kB. MQTT available via our API. #IoTDev #EdgeComputing #AssetTracking eelinktech.com/blog/eelink-p…
