A high data rate LiFi integrated system with inter-cell interference management

In this paper, we describe the first fully integrated Optical Wireless Communication (OWC) network solution with inter-cell interference management. This network uses novel LiFi integrated and real-time modems that implement advanced physical (PHY), Medium Access Control (MAC) and Logical Link Control (LLC) layers allowing adaptive rates up to 42 Mbit/s at PHY layer and a configurable number of supported users per lamp. On top of that, a network layer is designed and implemented to manage inter-cellular interference optimizing the spatial reuse of the resources. Hence, link quality of interfered unserved users is improved and the aggregated network throughput is drastically increased for typical indoor deployment compared to existing solutions without interference management. This whole system eases the deployment of LiFi lighting access points' networks in a dynamic auto-discovery manner (i.e., reconfiguration without operator's intervention).
