High Transmission Bit Rate of Multi Giga Bit Per Second for Short Range Optical Wireless Access Communication Networks
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.
