LoRaWAN technology has become a key communication solution in the LPWAN (Low-Power Wide-Area Network) space, thanks to its characteristics of low power consumption, wide coverage, and massive connectivity. However, with the rapid growth in the number of IoT devices, the limitations of traditional LoRaWAN gateways in terms of frequency points and channel capacity have gradually become a bottleneck for system scalability and deployment flexibility.
Most LoRaWAN gateways based on the SX130x chipset only support 8 frequency points and 16 channels of concurrent processing. This configuration can easily lead to packet collisions, increased packet loss, and communication delays in high-density or large-scale coverage environments, affecting system stability and data real-time performance.
Manthink’s GDO518-DG series LoRaWAN outdoor gateways break through these limitations and support 16 frequency points and 32 channels of concurrent processing, offering a more powerful and flexible networking solution for complex deployment scenarios.
Key Advantages of the GDO518-DG Gateway
- ✅ 16 Frequency Points + 32 Concurrent Channels
- ✅ Supports multiple combinations of frequency points and channels for flexible scenario adaptation
- ✅ Dual-antenna deployment for improved coverage and signal stability
- ✅ High-performance hardware design suitable for outdoor and complex environments
- ✅ Fully compatible with LoRaWAN 1.0.x protocols and supports major NS platforms (e.g., TTN, ChirpStack, ThinkLink)
Application Scenario 1: High-Density Device Environments – Increase System Capacity
In scenarios with a large number of devices, such as smart campuses, intelligent buildings, and industrial monitoring, traditional gateways with 8 frequency points and 16 channels often suffer from communication congestion and data collisions.
The GDO518-DG gateway supports 16 frequency points and 32 channels, doubling the system’s concurrent capacity. This significantly reduces communication pressure, improves data reception success rates, and enhances network stability and scalability.
Application Scenario 2: Wide-Area Coverage – Improve Signal Reception
In large-scale or complex terrain environments, such as smart agriculture, smart water management, and urban infrastructure monitoring, a single antenna and limited frequency points often fail to provide full coverage.
The GDO518-DG gateway supports dual-antenna deployment. It can be configured with two identical sets of 8 frequency points, enabling signal redundancy and coverage enhancement. This improves the gateway’s reception capability in challenging environments, expands communication range, and increases connection reliability.
