RFD868x-EU Modem
RFD868x-EU - is the flagship product of the Australian company RFDesign
RFD868x-EU Modem is a device certified in the European Union. This version, has limited operating modes of low power (5mW) - with full fill and high power mode (500mW) - with low fill. The low-power mode significantly reduces range and the high-power mode will significantly reduce throughput. These modes are in accordance with EU requirements and cannot be changed.
RFD is a long-range telemetry and communication system. The RFD system consists of RFD modems, a set of antennas and the cables necessary to connect the modules to other systems.
For more on RFD modems, their differences and applications, see our authoritativearticle..
At the heart of each system are RFD modems, which are high-performance radio modems operating in the ISM (Industrial, Scientific and Medical) band. They are designed for long-range communications applications requiring best-in-class radio link performance. One of the modems is always part of the GCS (Ground Control Station), while the other is part of the project with which communication is required, such as an unmanned aerial vehicle.
