Abstract
To increase the bit rate over than 1 Gb/s in LED visible light communications, we need to reduce the multipath effect of the light in indoor environment. In this paper, we propose a MAC protocol for LED visible light wireless LAN with beamforming technique. We assumed that spatial light modulator is used for beamforming function. We use polling method since detecting another uplink channel is difficult in visible light communication. We also estimated the performance of the proposed MAC protocol.
