Temperature and humidity monitoring are essential to pharmaceutical quality throughout the entire supply chain. China’s Good Supply Practice (GSP) requires continuous data logging, precise accuracy, real-time alerts, and long-term record retention. This article compares communication technologies including 4G, WiFi, LoRa, and LoRaWAN for battery-powered monitoring devices and highlights the KS52 LoRaWAN sensor series. Offering ultra-low power consumption, long-range transmission, and regulatory-compliant precision, the LoRaWAN solution enables secure and efficient environmental monitoring for pharmaceutical warehouses and cold chain logistics.
1. Key GSP Compliance Requirements
| Requirement | Standard | Compliance Purpose |
|---|---|---|
| Data retention | ≥ 5 years | Traceability for audit and regulatory review |
| Logging interval | ≤30 min storage / ≤5 min during transit | Ensure accurate environmental tracking |
| Alarm rule | Immediate alert with ≤2 min interval | Real-time anomaly response |
| Accuracy | ±0.5℃ / ±5%RH | Drug stability protection |
2. Comparison of Wireless Connectivity for Battery-Powered Sensors
| Communication | Power Usage | Coverage | Interoperability | Maintenance | Meets ≥5-yr Battery Life |
|---|---|---|---|---|---|
| 4G | High | Excellent | Good | High | ❌ |
| WiFi | High | Limited | Depends on network | High | ❌ |
| LoRa | Low | Wide | Vendor-dependent | Medium | ✅ |
| LoRaWAN | Ultra-Low | Wide Area | Standardized | Low | ✅✅✅ |
➡ LoRaWAN enables the most compliant and sustainable pharma monitoring systems.
