Up-Link Personnal Exposimeter DEVIN5G: RF Performance Validation

DEVIN5G is a miniature personal Up-Link (UL) exposimeter attached to the user mobile cover. It has been designed for two different goals: 1) for epidemiologists, it assesses the long-term evolution and diversity of electromagnetic field (EMF) exposure of a population; 2) for Telecom engineers, it is able to quantify the impact of a new technology or usage, on the UL exposure from the mobile or handled EMF source. DEVIN is dedicated to i) measure the transmitted (Tx) power emitted by the mobile phones and ii) identify the mobile phone usage, including its relative position with respect to the human body. With 5G roll off, this new version of the in-situ exposimeter has been released supporting seven UL cellular bands (from 717 MHz to 3500 MHz) and two Wi-Fi bands (among which WiFi6E standard). Moreover, it is able to detect Tx scheme of antenna switching, where the phone may emit signals using multiple antennas. The RF performance validation is discussed in this paper.
