Range is the greatest distance over which two radios can effectively communicate. While range is always important, in many IoT applications it’s essential to predict the quality of long-distance links before installation. For example, in oil and gas monitoring applications, a radio link may have to travel several kilometers from on-site equipment to a central monitoring station. It’s best to know if a designer’s chosen solution is likely to work before heading into the wilderness to deploy it. The XCTU provides automated and graphical tools for complete loopback range testing so that entire systems, including antennas, cabling, and environmental factors can be included in the predictions. Now a developer’s Digi XBees® can really go the distance.
