The development of optical wireless communication systems is accelerating as a cost-effective alternative to fibre optic links and wireless technologies. The optical wireless technology is used mostly in wide bandwidth data transmission applications. This technology can also be useful for cellular applications. The evolution of cellular networks, for increased coverage and capacity and for the evolution towards 3G, leads towards the necessity of increasing the number of base stations. The idea of using wireless optical links to implement additional base stations is introduced. A detailed analysis and measured results of optical wireless links utilised to transmit cellular signals are presented.
