Abstract

The invention concerns a data transmission system within a Local Area Network in which data is transmitted from a sender to one or more receivers using visible or near visible light. The system provides a ceiling or floor tile (13) which can be incorporated into convention floors or suspended ceilings. The tile (13) includes one or more aperture (12) through which light carrying the data can enter or leave the tile (13). The or each aperture (12) connects to a waveguide (15) within the tile (12), which waveguide (15) guides the light, typically having a wavelength of from 10'4 - 10''9m, to the or each receiver. Within the network each user can be allocated a wavelength by which data is to be transmitted to that user. The machine used by that user can then be configured to decode information carried by that particular wavelength.
