On the Performance of Hybrid LiFi-RF Network Using Freeform Based Angle Diversity Receiver

The recent release of the IEEE 802.11bb-2023 global light communication standard opens up exciting opportunities for LiFi-enabled devices to work seamlessly with RF technology. In this study, we extend our previously reported research on freeform-based angle diversity receiver by using it for a multiuser indoor hybrid LiFi-RF framework. The network performances have been investigated in terms of throughput, packet loss ratio and latency. The off-axis quadrilateral field of view of the freeform-based receiver offers excellent resilience against inter-channel interference. The result shows, nearly 300 Mbps average user throughput when 10 users are in motion inside the indoor environment. Moreover, exemplary improvement in overall system throughput has been observed compared to state-of-the-art research in the presence of light-path blockage.
