1. A method for operating at least one LED unit of a lighting grid comprising a plurality of LED units, comprising the steps of:
emitting light from the LED unit, the emitted lighted including a VLC signal to transmit data via the VLC signal;
capturing the light emitted by the LED unit with light capturing modules of a plurality of user equipment devices;
decoding, with each user equipment device, the VLC signal transmitted by the LED unit from the light captured by the light capturing module of the particular user equipment device;
determining, with each user equipment device for the LED unit, a VLC quality parameter which represents a quality of a transmission of data via the VLC signal transmitted by said LED unit;
determining a VLC control parameter for the LED unit, based on said VLC quality parameter;
adjusting the VLC signal transmitted by the LED unit based on the VLC control parameter;
determining with each user equipment device, from the captured light from the LED unit, a light intensity parameter which represents an intensity of the light transmitted by said LED unit;
comparing the light intensity parameter with an intensity reference value;
determining an intensity control parameter for the LED unit, based on said comparison; and
adjusting the intensity of the light emitted from the LED unit based on the intensity control parameter.
