  "description": "<p>In this paper, we consider integrating VLC and WiFi technologies in a scenario in which Light-Emitting-Diodes (LEDs), acting as network access points (APs) for ultra-dense Internet of Things applications, are deployed into an indoor lighting infrastructure. In such a scenario, RF-links can be exploited for complementing VLC-links in dealing with mobility and bidirectional communications, which can be problematic due to the limited coverage areas and self-generated interference of VLC APs. In particular, we consider the possibility of supporting a technology-based duplexing scheme, in which downlink and uplink transmissions are performed by means, respectively, of VLC and WiFi interfaces integrated into the same node.</p>\n\n<p><br>\nIn order to fully exploit the VLC bandwidth in the presence of background WiFi traffic and multiple coexisting VLC links, we discuss the importance of adopting a prioritization mechanism based on EDCA, as well as frame aggregation, for the uplink channel of the integrated architecture. Our considerations are corroborated by numerical results based on NS-3 simulations and a real simple experiment.</p>",
