Optical Signal Transmitter and Optical Wireless Communication Network Using It
摘要
<p>An optical wireless communications network connects a plurality of communication cells, which are defined by dividing a local communication area, for enabling optical wireless communication in each of the communication cells. An optical signal transmitter is installed in each communication cell for irradiating the cell with a data-modulated optical signal to perform data transmission to a terminal located therein. The optical signal transmitter comprises an optical signal source for outputting the data-modulated optical signal, and an optical signal diffuser with a concave inside surface facing the output end of the optical signal source for diffusing and reflecting the data-modulated optical signal to irradiate the cell.
