Understanding the Indoor Interference between IEEE 802.15.4 and IEEE 802.11b/g via Measurements

摘要：

IEEE 802.15.4 and IEEE 802.11b/g work in the same 2.4GHz ISM (Industrial Scientific and Medical) band, their coexistence is crucial to ensure both of them work efficiently under the interference of each other. In this paper we investigated the above issue through extensive indoor measurements in a systematic way. The experimental results show that (1) 802.11b interferes to 802.15.4 in a larger frequency range but with less interference strength, compared to that of 802.11g; (2) 802.15.4 also has serious impact on the performance of 802.11b/g; (3) different modulation methods of 802.11b/g have different impacts on the link performance of 802.15.4; (4) There are obvious interference ranges for 802.15.4 to 802.11b/g. We believe the measurement results are valuable for the real world deployment and design of the network integrated 802.15.4 and 802.11b/g.
