Abstract

Abstract: An experimental study of IEEE 802.15.4 anti-interference ability when it is coexistent with Wireless Local Area Networks in 2.4 GHz band is carried out. Communication quality of IEEE 802.15.4 is tested in a variety of scenarios and in practical application environment. Packet loss rate of IEEE 802.15.4 reaches as high as 94% due to the interference of WLAN as showed by the experimental data. This paper analyses correlation of packet loss rate of IEEE 802.15.4 communication nodes with WLAN channel, output power of nodes and RSSI and it provides a valuable experimental basis for the study of frequency anti-interference of WSN technology.
