Abstract
In this paper, a functional LiFi real-time testbed
implemented on FPGAs is presented. The setup evaluates the
performance of our design in a downlink scenario where the
transmitter is embedded on the streetlights and a mobile phone’s
camera is used as receiver, therefore achieving the goal of
lighting and communicating simultaneously. To validate the
design, simulations of the whole system are performed. where
simulations of the channel between streetlight and mobile device
show the scope of the reflection in an outdoor environment. The
measurements are carried out to characterize the modulator, in
particular the FPGA resources and latency due to the encoder
blocks. In addition the feasibility of the communication function
in presence of the ambient light is verified.
