This article presents the performance study of a ZigBee module with an external low-noiseamplifier, measured in both outdoor and indoor environments. Our previous study has already shownthat the indoor campus environment such as walls and floors would reduce the radio link rangedrastically and the packet error rate increased. In this study, an external low-noise amplifier has beenadded to a ZigBee module to increase the receiver sensitivity. It is shown that with an external lownoiseamplifier the outdoor radio range can reach up to 403 m with a negligible packet error ratecompared to 144 m without the low-noise amplifier for point-to-point connection. Thus, by increasingthe receiver sensitivity the radio range can be increased without increasing of the radio power outputso that the power consumption can still be kept low to obtain long battery lifetime.
