Videa
Network planning and design with the use of a sheet of paper and a pencil is laborious and entails the risk of error. Free software from TERRA - SatNet - allows to design installations based on the equipment manufactured by the company. The program allows to prepare the project in graphical form, to determine signal levels in all outlets and verify if they are compliant with standards, and to decide whether to use equalization function of the amplifiers. The program enables the user to archive the designs.
