Abstract

Abstract: A LED beacon based indoor positioning system is designed, which has advantages of low power, low cost and simple modulation/demodulation. Experimental results show the use of optical antenna can improve the BER performance of visible light communication system. The minimum delay to receive beacon ID is 76 ms, and the positioning accuracy is around 20 cm when the LED beacon height is 1 m.

Key words: visible light communication, indoor positioning, bluetooth low energy
