1. Overview of the LoRaWAN Gateway
As shown in Figures 1 and 2, the gateway receives data from Sushi Sensors through
LoRaWAN and sends it to the application via a LAN or the Internet. The gateway establishes
communications with the application’s data collection server.
Tocongurevariousgatewaysettings,useaPCandaWebbrowserthatrunsonit.
Encryption key for ensuring LoRaWAN communication security is determined by the Sushi
Sensor system administrator. Set this encryption key to the gateway, and store the same key in
the Support server.

App key. Then, this encryption key is written to the Sushi Sensor through the NFC function of the
Android device.
AndroiddevicecanalsoacquireencryptionkeyviaanNFCcard.
Details on the gateway settings and procedures used to set encryption key are described in the
following chapters.
