The lack of wireless spectrum in the radio frequency bands has led to a rapid growth in
research in wireless networking using light, known as LiFi (light fidelity). In this paper an …

Motivated by the looming radio frequency (RF) spectrum crisis, this paper aims at
demonstrating that optical wireless communication (OWC) has now reached a state where it …

Explores the fundamentals required to understand, analyze, and implement space
modulation techniques (SMTs) in coherent and non-coherent radio frequency environments …

In this paper, a hybrid radio frequency (RF) and visible light communication (VLC) system is
considered. A hybrid system with multiple VLC access points (APs) and RF APs is designed …

The increasing number of mobile devices challenges the current radio frequency (RF)
networks, eg wireless fidelity (WiFi) networks. Light Fidelity (LiFi) is considered as a …

This paper investigates the joint problem of access point (AP) assignment and power
allocation (PA) in a three-tier hybrid radio frequency/visible light communication (VLC) …

In this paper a fractional frequency reuse (FFR) technique is considered in a direct-current
optical orthogonal frequency-division multiplexing-based optical attocell network. An optical …

This chapter starts by explaining the significantly increased interest in visible-light
communications (VLC) and light fidelity (LiFi) during the last 10 years. Next, a taxonomy of …

In a multiuser bidirectional visible light communication (VLC), a large number of LEDs or an
LED array needs to be allocated in an efficient manner to ensure sustainable data rate and …

Energy efficiency (EE) and spectral efficiency (SE) have been identified as key performance
indicators in the design of future cellular networks. However, the available radio frequency …
