Abstract
Light Fidelity (LiFi) is complementary to Wireless Fidelity (WiFi) that uses light as the communication medium with leveraging the indoor lighting infrastructure. LiFi has limited coverage but provides a higher data rate, in contrast WiFi has broader coverage with a comparatively lower data rate. The hybrid LiFi/WiFi network (HLWN) takes advantage of both LiFi and WiFi to provide higher average data rate with over a larger coverage area. In HLWN, LiFi and WiFi can coexist and complement each other, as the spectrum of LiFi and WiFi are non-overlapping and non-interfering. In this work, we demonstrate the realistic performance of a hybrid LiFi/WiFi network in a physical testbed environment for different indoor scenarios and evaluate its data rate and handover latency performance
