“…In this paper, a four branch ADR (see Figure 2) with narrow FOVs was used to collect signals and reduce the inter-symbol interference (ISI). The design is based on the ADRs in [12], [13], [23], [26]. Each photodetector in the ADR is oriented to different direction to cover different areas in the room based on two angles: Azimuth (𝐴𝑧) and Elevation (𝐸𝑙).…”

Providing high data rates is one of the drivers in visible light communication (VLC) systems. This paper introduces a VLC system that employs angle diversity transmitters with beam steering to provide high data rates. In this work, red, yellow, green, and blue (RYGB) laser diodes (LD) are used as transmitters to obtain a high modulation bandwidth. Two types of RYGB LDs units are used in this paper: angle diversity transmitters (ADT) RYGB LDs light unit (for illumination and communication) and RYGB LDs light unit (for illumination). In addition, a four branch angle diversity receiver (ADR) is used where we study the delay spread and SNR. The proposed system was compared to the normal VLC system. A data rate up to 22.8 Gb/s was achieved using simple on-off-keying (OOK) modulation.

“…The 𝐸𝑙 angles of the seven detectors set as follow: six detectors are set at 40°, while the detector that faces upwards is positioned at 90°. Whereas, the 𝐴𝑧 angles of detectors are 0°, 60°, 120°, 180°, 240°, 300° , and 0°, respectively [23]. The FOV of the six detectors is set to 25°, while the detector that faces upwards has a 30° FOV.…”

Interference between cells or users can have a significant impact on the quality of optical wireless communication (OWC) links. This paper studies the co-existence of infrared based Micro cells with Visible light communication based Pico and Atto Cells for downlink communication. The signal to noise ratio (SNR) of each cell and the signal to interference and noise ratio (SINR) between cells are evaluated when an angle diversity receiver and an imaging receiver are used. The results show that Atto cell systems provide higher SNR and data rates compared to the Pico cell systems which provide higher SNR and data rates compared to Micro cell systems. The Micro cell systems however provide mobility as they provide a larger coverage area, followed by the Pico cell systems.
