Performance Analysis of Indoor FSO Communication Systems under Receiver Mobility

Abstract

There has been a tremendous growth in the recent years in the telecommunication traffic demand which is being scaled at much faster rate then anticipated. However, last mile technologies especially the indoor last mile connectivity continue to evolve in terms of complimenting techniques to the existing wi-fi systems. In this paper, an indoor free space optical mobile communication system is explored with a fixed transmitter location and moving receiver. The mobility refers to the movement of receiver within the room which results in significant changes among key performance parameters. Some of these important parameters which undergoes the spatial variations are signal to noise ratio, propagation delays, power delivery at receiver and impulse response at different receiver locations. We analyze these system parameters for moving receiver at different indoor locations.
