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 ....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

The Carpet Loop II is an ideal step upward for the listener who wants something better than a random wire but doesn't want the expensive dice roll of an active antenna.

The Carpet Loop is made up of two components: A tuner, and the antenna cable itself; the cable can be either 5-conductor rotator cable or 4-conductor flat phone cable, both readily available from Radio Shack and elsewhere. The tuner couples the antenna to the radio, forming a (giant!) L-network. To tune the antenna, you turn a switch for best reception.

While NO antenna c ....etc
