Revolutionary LoRa relay technology for unprecedented network capacity and efficiency
FRESHDATA Relay is our proprietary relay technology that fundamentally transforms LoRaWAN network architecture. By introducing intelligent relay nodes, we've solved critical scalability and energy efficiency challenges that have limited traditional LoRaWAN deployments.
Our patented approach enables networks to support 10x more devices while simultaneously extending battery life and coverage range—a breakthrough that opens new possibilities for massive IoT deployments.
Intelligent relay architecture for optimized network performance
Strategically placed relay nodes intelligently forward messages from end devices to gateways, extending coverage and reducing power consumption.
Advanced algorithms select optimal relay paths based on signal strength, network congestion, and energy considerations.
By offloading traffic from congested gateways to relay nodes, the network can support significantly more concurrent devices.
Real-world applications across diverse environments

Support for 10x more devices per gateway compared to traditional LoRaWAN, enabling truly massive IoT deployments without infrastructure multiplication.
End devices consume up to 80% less power by transmitting to nearby relays instead of distant gateways, extending battery life from years to decades.
Relay nodes fill coverage gaps and extend network reach into challenging environments like underground facilities, dense urban areas, and remote locations.
Reduce infrastructure costs by deploying fewer gateways while achieving better coverage and capacity through strategic relay placement.
End-to-end encryption is preserved through the relay layer, ensuring data security and privacy are not compromised.
Works with existing LoRaWAN infrastructure and devices, enabling gradual network upgrades without replacing existing equipment.
Deploy city-wide sensor networks for parking, waste management, environmental monitoring, and infrastructure management with minimal gateway infrastructure.
Monitor thousands of sensors across large industrial facilities, warehouses, and manufacturing plants with reliable, low-latency connectivity.
Cover vast agricultural areas with soil moisture, weather, and crop monitoring sensors using minimal infrastructure investment.
Freshdata Relay v1.0.0 — Technical Specification
Freshdata Relay is a LoRaWAN relay device that receives uplink messages from end devices and forwards them to a LoRaWAN gateway. Designed for scenarios where sensors cannot directly reach the LoRaWAN gateway due to distance, obstacles, or RF interference.

| Multi-Device Support | Manage up to 10 end devices simultaneously |
| Intelligent Scheduling | Learn device transmission periods for power-efficient operation |
| Dual Uplink Methods | Forward via LoRaWAN or RS485 |
| ABP Support | Supports ABP devices |
| Payload Decoding | Decrypts sensor payloads using AppSKey |
| Precise Sleep Timer | Less than 1 second drift per hour of sleep |
| Long Battery Life | Application dependent; can operate for several years on battery power |
| Robust Operation | Handles errors autonomously and runs reliably after initial configuration |
| User-Friendly CLI | Full configuration and monitoring via intuitive command-line interface |
Freshdata Relay operates through four sequential states:
| State | Description |
|---|---|
| Initialization | Hardware init, load config from flash |
| Registration | Operator adds devices via CLI |
| Exploration | Learn device TX timing; with period: 1 frame, without: 3 frames needed |
| Operation | Sleep → Wake → Receive → Forward cycle with adaptive wake offset |
| Power State | Current Draw | When Used |
|---|---|---|
| Deep Sleep | < 5 µA | Between scheduled receive windows |
| Listening | ≤ 10 mA | Waiting for device transmission |
