The rapid development of the number of wireless broadband devices requires that the induced uplink exposure be addressed during the design of the future wireless networks, in addition to the downlink exposure due to the transmission of the base stations. The aim of the project is to propose a 5G network planning method that optimizes the positions and power levels of massive MIMO-LTE (Long Term Evolution) base stations towards low power consumption, low downlink and uplink electromagnetic exposure and maximal user coverage. Such planning method would be beneficial for the operators since they can build-up cost-effective wireless networks, mainly in the developing countries like the D.R. Congo where grid energy harvesting is a big challenge. And that the same time, they can address the concerns about the exposure to the electromagnetic field.
