Outdoor Gateway Mesh with Sub-G Backhaul

Used for outdoor networks with Sub-G LoRa Backhaul for gateway-to-gateway communication.

The Gateway Mesh is an open-source protocol co-developed by ChirpStack and RAKwireless. It enables a multi-hop LoRaWAN mesh network, significantly extending coverage beyond standard single-hop gateways. Designed for outdoor scenarios, this solution uses Sub-G LoRa for gateway-to-gateway communication. You can choose either 8xx MHz or 9xx MHz LoRa based on your country’s LoRaWAN frequency requirements.

This option uses the sub-GHz band for relaying, providing long-distance coverage between gateways. It is a cost-effective solution as it requires only one concentrator, making it ideal for large areas like agricultural fields, remote monitoring sites, and expansive industrial facilities. However, the sub-GHz band is shared with end devices, which may lead to lower network capacity. Additionally, duty cycle limitations can vary depending on the region. Sub-G Relays are best suited for deployments where extending range is the primary goal and the message count remains in the low thousands per day.

Please select a LoRaWAN region according to this table:
