Overview of Wireless Optical Interconnection Development
无线光互连技术发展综述

In recent years, people's demand for wirless wide-band communication is growing stably. Because of the development of microwave wireless network, the bandwidth and frequency of radio wave are improved greatly. However, only wireless optical interconnection can meet the ideal wide-band requirement of data transmission. As the final schemes of many wireless communication systems, wireless optical interconnection techniques are also selected as the long-term solution strategies. Moreover, many advangtages of the wireless optical interconnection have not been fully mined and a lot of basic and application research need to be further carried out at both experimental level and commercial level. At abroad, the wireless optical transmission at Gb/s has been verified in laboratory. However, the indoor wireless optical interconnection system in use only can operate at the speed of 155Mb/s. In this paper, the transceiver, performance and security of the wireless optical interconnection technique are overviewed.
