ABSTRACT:
An optical wireless local area network according to the present invention is an optical wireless local area network for interconnecting a plurality of terminals having a line-of-sight optical communication function. In the optical wireless local area network, a base station including an angle diversity light reception function and a plurality of optical transmitters each having directionality is provided. The intensity of each of the plurality of optical transmitters can be separately modulated.
