How much data can a Digi XBee® send? Digi XCTU’s throughput tool allows users to measure the communications rate between any two modules. Simply connect one radio module to Digi XCTU, then test the bandwidth to and from any other Digi XBee radio on the same network. Designers can run a single test to check real-time throughput, or map bandwidth over time by running continuously to record bandwidth changes over time. The throughput tool is great for “what if” scenarios, quantifying performance in the lab, on-site network surveys, and more.
