1. Introduction
The R311CA is a dry contact detection device for Netvox ClassA type devices based on the LoRaWAN open protocol and is
compatible with LoRaWAN protocol. When any dry contact of R311CA detects a change, R311CA will send a message to the
gateway.
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 and 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.
