1. Core Challenge & Pain Points
The Problem
Cold chain failures rarely occur inside highly controlled warehouses. Instead, they cluster during transit and at physical handover points where environmental visibility drops to zero.
According to industry research:
- The Food and Agriculture Organization (FAO) reports that roughly 14% of global food is lost between harvest and retail, with temperature deviation during logistics being a major contributing factor.
- Industry estimates suggest that up to 20% of temperature-sensitive biopharmaceutical products may be compromised during cold chain transportation due to temperature excursions and handling issues.
Key Pain Points
- In-Transit Data Gaps: Fixed monitoring networks only cover warehouses. Once trucks hit the road, connectivity drops, leading to unnoticed temperature excursions and broken compliance logs.
- Item-Level Cost Barrier: While cellular trackers offer real-time updates, their high per-unit cost and aggressive power consumption make pallet-level or item-level deployment economically unfeasible. Conversely, traditional standard LoRaWAN deployments lack mobility when moving outside static gateway infrastructure.
- No Proof of Integrity: Without continuous and tamper-proof logging across the entire journey, receivers often lack verifiable evidence of temperature compliance—leading to disputes, rejected shipments, and financial losses.
2. Typical Customer Scenario
Consider a high-value, temperature-sensitive pharmaceutical shipment moving from a manufacturing facility in Mexico to a distribution center in Texas.
The journey begins with Handover 1 (Factory to First-Mile Carrier), where cargo is exposed to extreme ambient heat on an unshaded tarmac during loading. It then faces Handover 2 (Border Cross-Docking & Customs), where transferring goods to a domestic US fleet requires physical inspection, leaving trailer doors open and introducing risks of temperature spikes and cargo tampering. Finally, during Handover 3 (Final-Mile Delivery), scheduling mismatches at the destination warehouse force the truck to idle outside for hours, compromising product integrity just steps from the finish line due to cumulative stress across these unmonitored custody gaps.
3. The Hybrid Solution: BLE + LoRaWAN Architecture
By combining low-cost, item-level Bluetooth Low Energy (BLE) sensing with long-range, infrastructure-grade LoRaWAN connectivity, this joint solution achieves continuous visibility from origin to destination.
MOKOSMART BLE Sensors: Affordable, ultra-low-power tags placed directly on individual cargo/pallets for sensing.
- M4 Pro Waterproof Tag: Designed for warehouse asset tracking and temperature monitoring. Features data memory for offline backup.
- S05T Temperature Logger: A disposable, lightweight logger for export shipments. Stores up to 60,000 records and uploads data via BLE gateways.
- L02S Multiple Sensor: All-in-one tag tracking temperature, humidity, door open/close (hall effect), and transit shocks (accelerometer).
- DL002 Temperature Sensor Probe: Industrial-grade sensor with a 5-year lifespan and 60,000 local record storage; ideal for reusable cold chain containers.
MOKOSMART LoRaWAN Loggers：Long-range wireless logging designed for facility-wide coverage and real-time cloud uploading.
- DL001-LW LoRaWAN® Data Logger: A facility data logger featuring LoRaWAN® connectivity, built-in Flash storage, and a local display for real-time temperature, humidity, and battery status.
RAKwireless WisGate Edge Lite 2 (RAK7268CV2) Gateway: The network backbone deployed at fixed transit nodes to bridge edge data to the cloud.
- RAKwireless WisGate Edge Lite 2 (RAK7268CV2): An 8-channel industrial indoor gateway. Built for deep signal penetration in concrete/metallic environments (warehouses, distribution centers). Supports Ethernet, Wi-Fi, and Cellular backhaul.
4. End-to-End Logistics Journey
Origin (Logistics Park / Cold Storage): Pallets are equipped with MOKOSMART BLE sensors. The DL001-LW actively scans these local BLE signals, aggregates the environmental data, and instantly transmits it to the cloud via the warehouse’s static RAKwireless WisGate Edge gateway, preventing compromised goods from leaving the platform.
In-Transit (Refrigerated Truck): As the truck leaves the warehouse gateway zone, item-level BLE sensors continuously track individual pallets and broadcast data to the cabin-mounted DL001-LW data hub. Without active gateway coverage on the highway, the DL001-LW securely caches all incoming historical BLE sensor logs onto its built-in Flash storage, completely eliminating highway communication blind spots.
Destination (Retail Store / Distribution Center Bay): Upon arrival at the destination receiving bay, the DL001-LW automatically reconnects with the facility’s static RAKwireless gateway. It executes an immediate LoRaWAN data uplink of all cached in-transit logs to the cloud, generating a complete, unbroken audit trail before the trailer doors are even opened.
5. Key Benefits of the Joint Solution
- Seamless BLE-to-LoRaWAN Bridging: Combines the cost-efficiency of BLE tags with the long-range capability of LoRaWAN.
- Edge Reliability: RAK WisGate Edge Lite 2 ensures high throughput, strong signal penetration in metallic/concrete environments (like walk-in freezers), and built-in network server capabilities for local processing.
- Data Continuity (No Blind Spots): The storage mechanism of the DL001-LW guarantees that even without cellular or gateway coverage on the highway, the compliance log remains unbroken.
- Cost Efficiency & Scalability: Lowers total cost of ownership by using affordable BLE sensors for individual pallets, requiring only one LoRaWAN logger per truck/zone.
6. Conclusion
Cold chain operators do not just need data; they require continuous, verifiable visibility across complex custody handovers. By pairing MOKOSMART’s edge BLE sensing portfolio and scanning loggers with RAKwireless’s industrial gateway infrastructure, logistics providers can eliminate blind spots, protect high-value cargo, and deliver absolute proof of compliance from factory shelf to retail bays.
