  • Publication number: 20020141011
    Abstract: There is described a computer network in which a free space light beam is modulated to convey data to and from a network device. The light beam is generated by a signalling device which includes an optical system which collects the light beam and directs the light beam in an exit direction, and also includes a detector which detects the presence of a network device and a beam alignment system which varies the exit direction to align the light beam with the network device. The computer network has particular application in business premises such as an office. The computer network also has applications in public transport stations, for example an airport, and a public transport vehicle, for example an aeroplane.
