T Signal Losses and Allowable Optical Received Power Prediction Based on Different Visibilities for Optical Wireless

Infrared wireless communication possesses two main attractive advantages over its radio frequency counterpart, namely the abundance of unregulated spectrum in 1.3 μm–1.55 μm region and the ease with which the infrared radiation can be confined. Integrating microwave electronics and optics, it is possible to provide wideband communication services but it is well known that the signal level in an optical wireless receiver is weakest at the front end. This paper presented allowable signal losses and optical received power prediction based on different visibilities for optical wireless communication links over wide range of the affecting parameters.
