45 -Below shows the network structure for MQTT forwarding.
46 -
47 -* **For Uplink:**  The sensor sends data to LoRa Gateway via LoRa wireless, The gateway will process these data and forward to remote MQTT Broker via Internet.
48 -* **For Downlink:** The gateway subscribe a topic in the MQTT broker, when there is update on the topic, the gateway will know and broadcast the data to Local LoRa network,

56 -
57 -
58 -In this MQTT forward feature, the key point is how the gateway process the sensor data.

60 -
61 -=== 3.2.1  Upstream ===
62 -
63 -Assume there are two sensor nodes, their ID are Node1 ID: 6734 , Node2 ID: 7456. In the remote MQTT broker there are two topics: Topic1: /channel/765800, Topic2: /channel/367860. We can set up in the gateway to map Node1 to Topic1 and Node2 to Topic2. So when there is a sensor data from Node1, the gateway will forward the data to Topic1, when there is sensor data from Node2, the gateway will forward to Topic2.
