Compare of human head model SAR about different frequency radiation in BAN

In body area network (BAN),there is electromagnetic emission problem because it is a wireless network. It doesn´t reach an agreement that this radiation exists any harm to human body or not, and it is still under investigation. But there is no doubt that human body can absorb the electromagnetic emission energy. In this special body area network around human body, there must be some influence of electromagnetic emission on human body because the electromagnetic wave is so close to human body while launching and transporting and the network is working so long while it is being used. However human body has different SAR (specific absorption rate) for different frequency electromagnetic wave. In this paper, we have got the result about human head model SAR for different frequency electromagnetic wave in the computer simulation under BAN. By analyzing the result data, we have got this conclusion, in BAN, in a whole word there is less SAR for lower frequency electromagnetic emission, which has instructive significance for realizing BAN in the future.
