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
RAK7267for a cost-effective option with a built-in antenna
RAK7289V2for users preferring an external antenna
RAK7289CV2(with LTE) as the border gateway
You can purchase multiple relay gateways depending on the range you plan to cover for testing and deployment.
Reference:
All gateways use the latest SX1303 LoRa core, providing enhanced sensitivity and performance. The concentrator is shared for both end-device communication and mesh networking, which might impact overall network capacity.
