Characterization of EMF Exposure in Massive MIMO Antenna Networks with Max-Min Fairness Power Control

In this paper, we analyze the EMF exposure, in terms of total received power, in the massive multiple-input multiple-output (MIMO) networks. With the recent deployment of 5G networks, the potential risks of electromagnetic field (EMF) exposure are gaining increasing attention. However, most of the current research that focus on the mathematical modeling of 5G networks ignore downlink power control. Therefore, we derive the framework of the average power received at nearest mobile terminal MT under max-min fairness power control using stochastic geometry. The total received power consists of three parts, useful signal, multi-user interference and inter-cell interference. We propose a tight approximation on the power control coefficient. Based on the proposed approximation, the framework on total received power is then validated by Monte-Carlo simulations. The results show that the average received power monotonically increases as the density of the base station increases and the number of users increases.
