论文摘要

人们对人类健康的关注已被广泛认可 - 例如,眼睛和皮肤的加热 - 从无线发射器产生的电磁场(EMF)中暴露在内。移动电信依赖于通过EMF传输信号的大量基站(BSS)和手持设备的广泛网络。由于两个重要的变化,在将来的蜂窝网络中会看到两个重要的变化,因此有可能加重。首先,随着小细胞网络的扩散,BS的数量将显着增加,这将使人类更频繁地暴露于EMF。其次,将通过使用较大的天线阵列来克服更快的EMF能量衰减,例如毫米波(MMW)频谱来克服更快的EMF能量衰减,从而产生高度浓缩的EMF光束,如果主梁指向人体,则会增加损害。但是,可以利用这两个更改作为(i)更广泛选择替代BSS的利用,以及(ii)更精确的光束到所需的用户设备(UE),分别将EMF泄漏到其他方向。利用这两个变化,我们一直在研究5G无线系统的人类健康影响。该扩展摘要总结了我们到目前为止的发现。

Concern has been widely acknowledged about human health---e.g., heating of the eyes and skin--from exposure to electromagnetic fields (EMF) produced by wireless transmitters. Mobile telecommunications rely on an extensive network of base stations (BSs) and handheld devices that transmit signals via EMF. There is chance of aggravation due to two important changes that will be seen in future cellular networks. First, the number of BSs will remarkably grow with the proliferation of small-cell networks, which will expose humans to EMF more often. Second, highly concentrated EMF beams will be generated by employing larger antenna arrays to overcome faster EMF energy attenuation in higher-frequency bands such as millimeter wave (mmW) spectrum, which will increase damage if the main beam points to the human body. However, the two changes can be exploited as leverages for (i) wider selection of alternative BSs and (ii) more precise beamforming to a desired user equipment (UE) with less EMF leakage to other directions, respectively. Harnessing the two changes, we have been investigating the human health impacts of 5G wireless systems. This extended abstract summarizes our findings thus far.
