Benefits of the LoRaWAN wireless technology
- Operation in unlicensed band.
- Self-contained power supply of communication devices.
- High density of devices in the network.
- Connection safety and security of communication package.
- Reliable communication under industrial noise conditions.
- Two-way communication.
- Synchronization of system operation.
- High rate of network deployment and growth.
LoRaWAN network architecture
LoRaWAN network has a star of stars topology. It comprises end nodes, gateways, network server and application server.
The end node is responsible for measurement and control functions. It comprises a set of sensors and control elements.
The LoRaWAN gateway is a base station, which receives data from the end nodes by means of radio channel and transmits data to the transit network (such as Ethernet, cellular networks etc).
The gateway and end-nodes have a star topology. Several base stations ensure a network coverage and transparent duplex transmission between the end-nodes and server.
LoRaWAN allows to build wireless wide area networks with a large number of end nodes. One LoRaWAN gateway can serve up to 5 thousand end nodes. It is achieved by means of network topology, adaptive data transfer rate, time division and frequency-division channeling.
The network server is intended for network management by means of setting a schedule, rate adaptation, received data storing and processing.
The application server accumulates all necessary information from the end nodes and can remotely control their operation.
Applications and services
Smart metering is based on specialized industrial services.
We have developed the ENERGOKabinet cloud service with consideration of industrial processes features, such as the metering instruments lifecycle.
Due to combination of LoRaWAN technologies and ENERGOKabinet cloud service the IoT solutions for utility and energy companies are easy to implement.
Meters and sensors
Ultrasonic heat meters KARAT-223 and ultrasonic water meters KARAT-523 serve as metering instruments in our systems. These are the new generation meters designed for use in digital world. They differ from the previous generation devices by the integrated radio-interface of the LoRaWAN standard. This allows the meter to connect to networks and send data to services anywhere in the world.
