Packet Broker is a service for exchanging traffic with other LoRaWAN networks to share coverage and improve the overall network performance. It sits between LoRaWAN network servers and acts as the backbone for LoRaWAN traffic. It routes uplink messages from forwarding networks to home networks based on the device address in the uplink message and also routes downlink messages to the end device from the home network to the forwarding network for transmission by the gateways. Packet Broker also supports device activations and is fully compatible with all current LoRaWAN versions.
The typical issue arising in the traffic exchange is network servers discarding messages received from guest networks. Packet Broker aims to improve the exchange of traffic between networks. With Packet Broker, the home network accepts messages from the end device and routes them to the network. The device can also receive downlink messages. Once the networks have started to exchange messages, the end device can lower its spreading factor if there are any gateways closer by. The same mechanism will apply if there is a gateway failure in the network or loss of the signal quality by various obstacles.
Packet Broker provides several advantages to network operators and application developers:
Packet Broker enhances existing features of LoRaWAN:
Packet Broker is compatible with LoRaWAN passive roaming, allowing for it to be compatible with The Things Stack Community and The Things Stack Cloud, as well as third-party Network Servers, such as ChirpStack or any other.
The Things Stack Community Edition and The Things Stack Cloud are already connected to Packet Broker. Configure Packet Broker
