Optical beamforming is a technique to focus light-emitting diode (LED) light on a desired target and has been used to improve the performance of visible light communications (VLC). In this article, we propose and demonstrate a VLC technology based on time-division multiple access (TDMA) optical beamforming to accommodate multiple target devices. It focuses LED light on each different target device in each different time slot. Our results show that the proposed technique can accommodate multiple target devices and also gives the benefit of optical beamforming (5~10 dB gain) to each target device. Our results also show that the transmission distance increases from 110 to 200 cm with the TDMA optical beamforming.
