| 摘 要： | 针对2.4 GHz频段内的IEEE 802.15.4，研究其与无线局域网共存时的抗干扰性。实验设定了多种场景并测试了实际应用环境中IEEE 802.15.4的通信质量。实验数据表明，WLAN干扰可使IEEE 802.15.4数据丢包率高达94%。通过实验数据分析得到了IEEE 802.15.4通信节点丢包率与WLAN信道、节点发送功率以及RSSI的相关性，为研究WSN的同频抗干扰技术提供了有价值的实验依据。

| 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. |
