AMR – Wireless LoRaWAN Systems
Wireless LoRaWAN is a wireless open protocol communication technology. It has been specially designed and optimised for applications such as smart city infrastructures, efficient waste management and smart metering.
LoRaWAN refers to the open standard managed by the LoRa Alliance. The communication takes place via LoRa radio technology and includes all aspects of the solution which are defined by LoRaWAN. This also includes end-to-end security or end-to-end encryption.
As with all wireless technologies that use unlicensed frequency bands, there is the possibility of interference from other radios. Because every broadcaster competes for the same resource when transmitting: “Airtime”. This is because the signal between transmitter and receiver is attenuated by physical objects. However, compared to other wireless solutions, LoRaWAN offers enormous range and a strong ability to penetrate physical obstacles.
LoRaWAN is particularly suitable for battery-powered sensors with low resolution and simple measuring instruments. Compared to Wireless M-Bus, in many cases it can be considered a similar but improved wireless solution.
However, it is important to note that LoRaWAN has a different ecosystem with specific infrastructure requirements. It is more dependent on supporting cloud services than wireless M-Bus.
In addition to energy management, the open LoRaWAN standard can also be used to collect other relevant data in an intelligent building. The smart LoRaWAN sensors are able to record motion, heat, noise, distance and air composition data and transmit it to the central building management system. Based on this information, internal building processes can be optimized. For example, the CO2 content of the indoor air can be measured to improve ventilation behaviour.
To build a LoRaWAN network, you need gateways that receive the network signal from LoRaWAN sensors and forward it to a network server. Here it is then possible to visualize the data or adapt it for a special system to process the data.
LoRaWAN gateways then collect data from all meters in the network and create an interface to the Meter Data Management software or can be exported directly, for example in csv format.
Available LoRaWAN Products include:
- Metering Gateway for Mobile Networks
- LoRaWAN Ready Smart Meters
- Temperature & Humidity Sensors
- CO2 Sensors
- Movement / Door Sensors
- Leakage Detection Sensors
- IOT Data Collection Platform
