The MFW radio systems from EES have always been characterized by their reliable operation and their large transmission ranges. The classic 35cm and 70cm ISM bands with FSK modulation are now joined by LoRa and LoRaWAN technology, which is based on a spread-spectrum method. The advantage of this method, especially for the MFW system, is the energy-saving operation and the increased reception sensitivity, so that applications in basement rooms or from shafts can also be adapted well.
LoRaWAN recognizes different operating modes, which are divided according to so-called classes A,B and C. These define the readiness to receive especially with regard to the downlink channel, i.e. from the gateway to the end node, and thus also the energy consumption of the MFW. The class is set via the parameterization program, so that, in simple terms, the MFW is more energy-saving and therefore less accessible for transmission of command or setpoints, or permanently accessible but not energy-saving.
An MFW LoRaWAN station is especially suitable for the connection of sensors and measurement technology, which do not provide a LoRaWAN interface themselves and can be integrated into the application through the multitude of connection options of the MFW. The MFW radio telegrams are optimized for the LoRaWAN technology and compressed accordingly, so that the air interface is used ideally.
For the application side (server), appropriate precautions must be taken, e.g. how the visualization and further processing can take place. We will be happy to provide you with recommendations in this regard.
