With its R&S SpaceMan DS101 system, Rohde & Schwarz is the first supplier worldwide to combine broadband satellite-systems with radiocommunication. Requests to the Internet are made via radio (HF/VHF/UHF), and transmission of requested data via fast satellite links.
Access to this modern information technology (IT) with radio linkup is realized by means of PostMan, a well-known software product which allows transparent TCP/IP radio data transmission. PostMan in conjunction with shortwave transceivers of the XK2000 Family provides unrestricted access to wired communication networks via radio links from any point on the earth.
Reception of satellite signals is implemented in R&S SpaceMan by commercial system solutions adapted to radio technology. This provides wireless Internet access unimpeded by the constraints of low data rates.
Through the combined use of two transmission techniques - radio and TV satellite - R&S SpaceMan (FIG 1) achieves data rates far above those of terrestrial post office lines with telephone modems. A user browsing on the Internet from a ship in the North Sea for example, using shortwave and satellite links provided by SpaceMan, is at no disadvantage compared with his mainland workstation.
Using satellite transmission and radio technology from Rohde & Schwarz, large volumes of data such as digital maps, databases and software upgrades can be downloaded to the PC far from any infrastructure at data rates considered so far unattainable in radiocommunication. Even realtime multimedia applications can be implemented in this way.
Thanks to R&S SpaceMan, users who so far could not access wired communication networks due to the lack of suitable infrastructure, now for the first time can enter the Internet from any point on the earth via radio links and at data rates unattainable for wired users up to now. SpaceMan thus opens wired communication networks also for users at sea, on islands or in other remote areas, and for land-mobile applications.
