Electro-magnetic field exposure reduction/avoidance for the next generations of wireless communication systems

在下一代通信网络中，为了支持指数级增长的业务需求，将不得不部署大量额外的接入点(即基站)来补充现有的接入点。如果不采取具体行动，这将提高普通公众暴露在其中的电磁辐射水平，并增加他们对此的担忧。这项研究工作的总体目标是研究通过将增加的接入点密度转化为优势来减少通信系统的电磁暴露的创新技术，这将是未来网络的基石。在网络中具有更多接入点给予例如以下方面更多自由度：通过同时连接/发送到几个接收器来降低移动设备的发送功率(即，主要曝光源)，或者仅连接/发送到不在用户头部/身体方向上的接入点。

In the next generation of communication networks, to support the exponential rise in traffic demand, a large number of additional access points (i.e. base stations) will have to be deployed to supplement the existing ones. If no specific actions are taken, this will raise the level of electromagnetic (EM) radiation that the general public is exposed to, and increase their concerns about it. The overall objective of this research work is to investigate innovative techniques for reducing the EM exposure from communication systems by turning the increased density of access points, which will be a cornerstone of future networks, into an advantage. Having more access points in the networks give more degrees of freedom to, for example; reduce the transmit power of mobile device (i.e. the main source of exposure) by connecting/transmitting to several receivers simultaneously, or to connect/transmit only to access points that are not in the direction of the user head/body.
