Editorial narrative

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: 800 MHz EU868/IN865/RU864 900 MHz US915/AU915/KR920/AS923 Solution characteristics (for sub-GHz relay) Devices per network Typically 1000 sensors, depending on topology and messages/day Distance between gateways Between 2 and 10 km, depending on locations Radio channels 8 RX + 1 TX Relay configuration Selectable SF, BW and TX power Channel hopping Maximum hops 8, recommended 3-4 Network monitoring Heartbeat messages Info page on LNS Network flooding management Per-gateway message ID cache Per-gateway max hop count Network security Standard LoRaWAN security for messages to/from end-devices Shared key for MIC checking for messages between gateways Gateway power Power adapter Battery Plus compatible (battery+solar) Gateway installation Pole mount The solution includes: One or more relay gateways RAK7267 for a cost-effective option with a
