Abstract

In the present paper, the backbone and the broadband wireless access communication network technologies can increasingly provide unprecedented bandwidth capacities, the focus being gradually shifted toward broadband access technologies capable of connecting the customer premises to the local exchange. Optical wireless is increasingly becoming an attractive option for multi giga bit per second within short range (up to 5 km) links where laying optical fiber is too expensive or impractical. For such links, a tracking scheme is essential to maintain proper pointing of the transceivers at each other to establish error-free communication. The optical wireless technology is used mostly in wide bandwidth data transmission applications. Also, we have investigated the maximum transmission distance and data transmission bit rates that can be achieved within broadband wireless optical links for multi giga bit optical network applications. The wireless optical broadband access network architecture has been proposed as a flexible solution to meet the ever-demanding needs in access networks. At the wireless front end multi channel communication, with routers having multiple radio interfaces tuned to non overlapping channels, it can be used to improve network throughput in a cost effective way.
