Combination of Free Space Optics (FSO) and RF for different wireless application scenarios

In this contribution Free Space Optics (FSO) in combination with other wireless technologies (including WLAN and satellite communications) is presented. Modular communication systems are considered, which allows worldwide access to the Internet or other networks by combining satellite communications, FSO, Wireless LAN, Local Multipoint Distribution System (LMDS) and DVB-T (terrestrial digital video broadcast). Wireless LAN offers connectivity to mobile users in a network cell, Free Space Optics allows quick installation of broadband fixed wireless links instead of cables and satellite communications provides a backbone between distant locations in the world. DVB-T is the current video broadcast standard (instead of former analogue TV) and will also be used for Internet-access (see project SEE TV-WEB). Different scenarios (and results) using modular wireless technologies are shown.
