【 摘 要 】

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