Visually-assisted optical indoor wireless local area network (LAN) is promising not only for high-speed but for offering intuitive user interface. Free-space optical communications (FSOC)(Jahns, 1994) are a key technology to create image-based ultra-fast wireless communication systems of the future. Compared with radio-frequency (RF) electromagnetic waves, the outstanding features of free-space...

Welcome to this Special Issue in which we explore recent thinking and developments concerned with the optical wireless communication systems and networks. The demand for access to higher data rate in wireless access network, wireless multimedia applications and wireless video is growing. There are mainly two technologies, radio and optical, capable of offering these services. Radio has the adva...

It is commonly agreed that the next generation of wireless optical communication systems, usually referred to as fourth generation systems, will not be based on a single access technique but it will encompass a number of different complementary access technologies. Communication topics such as modulation, multiplexing, and detection are discussed in relation to optical wireless links. Negative ...
