Mitigation of Human RF Exposure in 5G Downlink

TL;DR

This paper investigates human RF exposure in 5G downlink and proposes a protocol to limit EMF exposure while maintaining required data rates.

Contribution

It introduces the first analysis of downlink human EMF exposure in 5G and proposes a protocol to mitigate exposure without compromising data performance.

Findings

Human EMF exposure in 5G downlink is significant and warrants attention.

A novel protocol effectively limits EMF exposure while satisfying 5G data rate requirements.

Abstract

While research on communications at frequencies above 6 gigahertz (GHz) has been primarily confined to performance improvement, their potentially harmful impacts on human health are not studied as significantly. Most of the existing studies that paid attention to the health impacts above 6 GHz focused only on the uplink due to closer contact with a transmitter to a human body. In this letter, we present the human electromagnetic field (EMF) exposure in the downlink of Fifth-Generation Wireless Systems (5G). Moreover, we propose a downlink protocol that guarantees the EMF exposure under a threshold while keeping the data rate above the 5G requirements.
