Troposcatter radio systems provide communications beyond the horizon by using a radio path through the troposphere. A troposcatter system is a point-to-point link that requires a terminal on each end, with each terminal both transmitting and receiving. Terminals can range in size from a portable transit case system to a vehicle-mounted system or large fixed installation. The antenna(s) at each terminal are aimed at a fixed point in the troposphere, generally slightly above the horizon. The region where the antenna beams intersect is known as the “Common Volume.” The Common Volume is where this predictable scattering phenomena occurs.
Due to the nature of troposcatter propagation, only a tiny portion of the energy is scattered forward in a usable manner. The vast majority of energy passes on into space and is lost, and a small amount of non-useable scatter energy is lost as it disperses in other directions. A troposcatter system uses the remaining energy to create a stable and secure data link.
• Point to point communications beyond line of sight (over the horizon) between remote geographic areas where microwave and cable links are not feasible
• High capacity and reliability
• IP based system
• Provides a radio link with near instantaneous communications and very little delay latency as compared to satellite links
• Provides a reliable means of point to point links between remote hostile areas that are beyond line of sight
• Mobile troposcatter links can be installed in less than one hour, for high capacity 22 Mb/s links between two points separated by more than 100 km
