ZigBee offers low-cost mesh connectivity in hospitals, refineries, and critical infrastructure. This thesis explores two ZigBee Received Signal Strength Indicator RSSI-based rangefinding tool sets Z-Ranger and Zbfind. Z-Ranger is a new tool set developed herein for the Zena Wireless Adapter that offers configurable distance estimating parameters and a RSSI resolution of 256 values. Zbfind is an application developed for the Atmel RZUSB stick with no configurable distance estimating parameters and a RSSI resolution of 29 values. The two tool sets are evaluated while range finding four wireless devices indoors and two devices outdoors. Mean error is calculated at each of the 35 collection points and a99 confidence interval and p - Test are used to identify statistical deviations between the two. After three rounds of evaluation, the results suggest that calibrated distance estimating parameters along with an increased RSSI resolution do not statistically reduce mean error when compared to non-calibrated parameters and lower RSSI resolution. The result of this research is that Z-Ranger is shown to be an alternative range finding tool set that performs as well as Zbfind.
