• The deployment of 5G networks will necessarily involve the installation of new base station (BS) equipment to support the requirements of next-generation mobile services. In a scenario where there exist already many sources of electromagnetic fields (EMFs), including overlapping 2G/3G/4G technologies of competing network operators, there is a growing concern that the planning of a 5G network will be severely constrained by the limits on maximum EMF levels established in a wide set of regulations. The goal of this paper is to shed light on EMF-aware 5G network planning and, in particular, on the problem of site selection for 5G BS equipment that abides by downlink EMF limits. To this end, we present the current state of the art in EMF-aware mobile networking and overview the current exposure limits and how the EMF constraints may impact 5G planning. We then substantiate our analysis by reporting on two realistic case studies, which demonstrate the saturation of EMF levels already occurring under current 2G/3G/4G networks, as well as the negative impact of strict regulations on network planning and user quality of service. Finally, we discuss the expected impact of 5G technologies in terms of EMFs and draw the guidelines for an EMF-aware planning of 5G. Our analysis suggests that the EMF-aware 5G planning risks to be a real challenge for network operators, which stimulates further actions at governmental, societal, technological, and research levels.
