Internet-of-Things (IoT) based Wireless Body Area Networks (WBANs) are likely to change the traditional healthcare infrastructure by allowing remote monitoring of patients outside the conventional clinical settings e.g. in homes. However, technology remains a key enabler for such a system realization. Currently, Radio Frequency (RF-) based Zigbee networks are being employed for data transmission and reception, nevertheless, with the widespread use of IoT devices, the unlicensed Industrial, Scientific and Medical (ISM) spectrum may exhaust soon. Consequently, Visible Light Communication (VLC) technology is being considered as an alternative to RF owing to its extremely high unregulated bandwidth and low cost. Additionally, it is considered safe for human beings. Several studies in the literature have reported the effects of transceiver related parameters on a VLC link, however, in this study, we examine the impact of various parameters that are pivotal for VLC channel characterization in healthcare settings. We show that reflectivity of room surfaces, angle of irradiance of light emitiing diodes (LEDs), and on-body receiver heights have a significant impact on the received power (RXPWR). Furthermore, we validate that increase in number of transmitters (Txs) reduce the fluctuations in RXPWR by 75. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
