Free-space optical (FSO) communication system has become a popular option in the communication industry. This is due to the increasing demand of high-speed wireless optical links. The common wireless communication technology that is being deployed currently is the radio frequency (RF) technology. However, limited bandwidth and power efficiency are the vulnerabilities in this technology. FSO is then...
The availability and performance of terrestrial free-space optical (FSO) communication systems are heavily deterred by the fluctuating conditions of the atmospheric channel, particularly in the presence of visibility-limiting fog effects. In this paper, we examine the viability of deploying hybrid FSO and radio frequency (RF) links through an experimental study, which takes advantage of a dedicated...
The performance of free-space optical (FSO) communication system is investigated from the information theory perspective, under the influence of atmospheric loss and channel fading due to the turbulence and pointing error. The outage probability and average channel capacity of the FSO link are evaluated using a combined slow-fading channel model and a Gaussian beam wave model, unlike the limiting...
In-depth knowledge and understanding pertaining to the characteristics and short-term variations of solar radiation are essential, to promote the efficient utilization of solar energy. In particular, these findings are beneficial to tropical locations that are geographically positioned at the center of the “solar belt”, due to the abundant and persistent solar radiation encountered throughout the...
With the adoption of the fourth generation (4G) technologies, the green Metrozones concept presents a viable approach to address the non-negligible presence of power-hungry base transceiver stations (BTSs), and the mushrooming of metro access points (M-APs); and their contributions to the world's carbon footprint. This paper proposes a new hybrid-BTS (H-BTS) system architecture for the green Metrozones...
Visible-light communication (VLC) has been widely recognized as a promising candidate to realize a feasible deployment of Intelligent Transportation System (ITS). The undesirable ambient-light noise due to daylight remains as a major impediment to the VLC system. In this paper, we propose a time-variant non-clear sky channel model to enable a more realistic prediction of the system performance. Next,...
