White LED (Light Emitting Diode) is expected to be the next generation of lamps due to its properties such as high brightness, reliability, low consumption and long life span. In this article , the proposed system for indoor optical wireless duplex channel communication system, as an access to the Internet, utilizing both white LED lights and infrared LEDs is described. The illuminance and power distribution, impulse response, and modulation techniques has been studied in this article. LED lights and receivers design strategies has also been d ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of li ....etc

the WiFi-based localization system has been intensely studied
and demonstrated, we will only focus on the optical wireless
transmission. The wavelength of the transmitted optical signal
is generated in a CO with a DFB laser at 1550.12 nm and it is
modulated using 12.5 Gb/s PRBS data in on-off-keying
(OOK) modulation format. The modulated signal is transmitted
to the access point via 5.6 km standard single mode fiber. Then
this signal passes through a lens to increase its divergence before
propagating i ....etc

Abstract:
Knowledge of ambient optical noise is essential for designers of free space optical links, for resilient designs. In this paper, a complete experimental
characterisation of the most common ambient optical radiation is presented. The study includes Tungsten filamen t sources, low and high frequency
fluorescent lights, IR headphones, TV remote controls, and daylight. Means to reduce their influence on the performance of the links are also given.
The results are valuable towards setting a standard way of comparing wireless IR links, ....etc
