About LoRaWAN
The Sushi Sensor adopts the LoRaWAN communication system that has high-level receiving
sensitivity and resistance to radio-frequency interference, and that offers a communication
distance of 10 km or more in an ideal communication environment.
The LoRaWAN communication system is specifi cally designed for IoT (Internet of Things)
applications and provides power-saving and long-distance communication features standardized
by LoRa Alliance. Low power consumption contributes to a battery service life of several years,
and the long-distance communication feature expands the area that can be covered by a single
gateway and enables communications regardless of the location of the Sushi Sensor, thereby
simplifying installation and maintenance procedures.
The Sushi Sensor creates a simple star-type network in which sensors directly connect to the
gateway. The Sushi Sensor sends sensed data to the gateway. When receiving data from the
Sushi Sensor, the gateway transfers it to the pre-specifi ed application.
LoRaWAN does not support the data relay function. If there are any Sushi Sensors that cannot
directly connect to the gateway, you will need to add a gateway in the vicinity of the sensors.
LoRaWAN uses Sub-GHz radio frequency bands. The communication data rate is variable and
automatically optimized depending on communication conditions. LoRaWAN communications
are protected by AES128 encryption in both the network and application.
LoRaWAN provides three communication classes. To establish communications, the Sushi
Sensor uses the simplest and power-saving communication class that is referred to as “class A”.
