Device positions are computed based on measurements they make of neighbours. Therefore devices need to measure neighbours and report these measurements to the whereBox via a suitable Gateway device (also called an Edge device or Border Router).

This chart measures and plots the success rate achieved for reporting measurements to the wheeBox. Each device is drawn as a line against time representing the percentage of measurements that were successfully reported. It purpose it to monitor for a diagnose communications errors in the network - errors that may be induced by interference or other environmental factors, or even through overloading the network.
