We present the results of extensive field experiments designed to evaluate the precise relationship between wireless link quality, radio power level, and transmis- sion distance in outdoor embedded deployments. We focus on ZigBee networks, using Tmote Sky nodes, a popular commercial hardware platform for wireless sen- sor systems. The results are used to develop a piece- wise regression model suitable for pre-deployment link quality prediction. We characterize the contexts in which the model provides high accuracy, and discuss potential threats to validity.
