An optical communication access point comprises: an optical communication channel for allowing wireless light communication with a remote device, and a memory for storing content, wherein the content in the memory is accessible by the remote device via the wireless light communication link.

Li-drive

A luminaire driver apparatus for use with one or more light emitting diodes or other light sources, comprises voltage control circuitry configured to regulate a supply voltage to one or more light emitting diodes or other light sources; driving circuitry configured to provide a drive current to the one or more light emitting diodes or other light sources, the drive current being dependent on the supply voltage, wherein the driving circuitry is configured to modulate the drive current based on a modulated drive signal such that the one or more light emitting diodes or other light sources produces an optical signal, wherein at least one of the driving circuitry and control circuitry are operable to adapt to a plurality of different types of light emitting diode or other light source. Thereby providing a universal driver function.

Driver apparatus

A wireless cellular network includes a plurality of cells, each cell including a base station for serving one or more mobile users. For controlling an operation within a cell of the wireless cellular network, a fuzzy logic is used. The input variables for the fuzzy logic include input variables determined on the basis of information only locally available in the cell.
