1. Introduction
The R311FA is a Wireless Activity Detection Sensor for Netvox ClassA type devices based on the
LoRaWAN open protocol and is compatible with the LoRaWAN protocol.
When the device detects movement or vibration, it immediately triggers an alarm.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption.
Compared with other communication methods, LoRa spread spectrum modulation method greatly
increases to expand the communication distance. Widely used in long-distance, low-data wireless
communications. For example, automatic meter reading, building automation equipment, wireless
security systems, industrial monitoring. Main features include small size, low power consumption,
transmission distance, anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability
between devices and gateways from different manufacturers.
