摘要
对工科医(ISM)频段的家庭电磁环境进行了分析与测量,给出了测试波型与数据。应用一个通用的同频段干扰模型,对蓝牙无线网络在此电磁环境下的性能进行了仿真。测试了蓝牙无线网络在无线局域网(WLAN)和微波炉干扰下的性能影响。实验结果表明:蓝牙无线网络在家庭电磁环境干扰下性能最高下降了42%,工作受到了严重影响。说明如今的家庭电磁环境十分恶劣,应给予足够的重视。
This study analyzed and measured the electromagnetic aspects in 2.4 GHz band under home environment, and gave the measurement results and figures. And then simulated the performance of a bluetooth network in this EM environment used a common interference model. At last, this paper tested the performance of a bluetooth network under interference of 802.11g network and microwave oven. The results show that the performance of the bluetooth network in EM environment of home has been dropped by up to 42%. So more attention should be given to the terrible EM environment of home.
