RAK7431 Networking Applications

 

RAK7431 can convert the data of RS485 devices into LoRaWAN™ that can be sent to the 
cloud via a standard LoRaWAN™ Gateway. Cloud servers can also actively send data to 
RS485 terminals to achieve two-way data transmission. Using RAK7431, what used to be a 
costly and time-consuming cable line network deployment can be transformed into a rapid 
and cost-efficient wireless network deployment. 

 

An example would be using the RAK7249 LoRaWAN™ Gateway coupled with the RAK 
WisDM  cloud management platform, in order to realize an end-to-end industrial field data 
acquisition and control system. Using the built-in LoRa® Server, that comes standard with 
any RAK LoRaWAN™ Gateway, one could seamlessly achieve transmission of the end 
device data to any application server. Furthermore, the MQTT integration allows for a high 
level of security and efficiency.
