IEEE 802.15.4 commonly known as ZigBee is a Media Access Control MAC and physical layer standard specifically designed for short range wireless communication where low rate low power and low bandwidth are required. This makes ZigBee an ideal choice when it comes to sensor networks for monitoring data collection and or triggering process responses. However these very characteristics bring into question ZigBee s ability to perform reliably in harsh environments. This paper thoroughly explains the experimental testbed setup and execution to demonstrate ZigBee s performance in several practical applications. This testbed is capable of measuring the minimum maximum and average received signal strength indicator RSSI bit error rate BER packet error rate PER packet loss rate PLR and the bit error locations. Results show that ZigBee has the potential capabilities to be used in all four tested environments. 1. Introduction As digital technology is rapidly advancing in the 21st century much of this technology is oriented toward efficiently monitoring and reacting accordingly. Whether it is monitoring for building automation assembly line manufacturing or even .
