Journal ArticleDOI
Coexistence of WiFi and LiFi toward 5G: concepts, opportunities, and challenges
Moussa Ayyash,Hany Elgala,Abdallah Khreishah,Volker Jungnickel,Thomas D. C. Little,Sihua Shao,Michael Rahaim,Dominic Schulz,Jonas Hilt,Ronald Freund +9 more
TL;DR: The general characteristics of WiFi and VLC (or LiFi) are described and a practical framework for both technologies to coexist is demonstrated, to explore the existing research activity in this area and articulate current and future research challenges.
Proceedings ArticleDOI
A hybrid Radio Frequency and broadcast Visible Light Communication system
TL;DR: An indoor hybrid system that integrates WiFi and VLC luminaries, offers the bandwidth density benefits of VLC, provides a non-intrusive RF back-channel, maintains compatibility with conventional RF devices, and demonstrates excellent scalability.
Journal ArticleDOI
Design and analysis of a visible-light-communication enhanced WiFi system
Sihua Shao,Abdallah Khreishah,Moussa Ayyash,Michael Rahaim,Hany Elgala,Volker Jungnickel,Dominic Schulz,Thomas D. C. Little,Jonas Hilt,Ronald Freund +9 more
TL;DR: The hybrid WiFi-VLC system is proposed, which outperforms the conventional WiFi for crowded environments in terms of throughput and Web page loading time, and the further improved performance of the aggregated system when considering the blocking duration and the distance between the access point and the user device is demonstrated.
Proceedings ArticleDOI
An Indoor Hybrid WiFi-VLC Internet Access System
Sihua Shao,Abdallah Khreishah,Michael Rahaim,Hany Elgala,Moussa Ayyash,Thomas D. C. Little,Jie Wu +6 more
TL;DR: This paper proposes and implements a hybrid solution in which the uplink challenge is resolved by the use of an asymmetric RF-VLC combination, and the integrated system outperforms conventional WiFi for crowded (congested) multiuser environments in term of throughput.
Journal ArticleDOI
Toward practical integration of dual-use VLC within 5G networks
TL;DR: Motivating factors for VLC usage in environments with a high density of user devices are described, models for V LC integration with RF technologies are presented, system components required for practical deployment are defined, and scenarios where VLC integration is most beneficial are evaluated.
