  Providing uplink high data rate is one of the big concerns in visible light
communication (VLC) systems. This paper introduces an uplink VLC system based
on an infrared transmitter with beam steering to provide high data rates. In
this work, a 4 branches angle diversity receiver (ADR) is used and the
resultant delay spread and SNR are examined. The proposed system achieved data
rates up to 3.57 Gb/s using simple on-off-keying (OOK).
