Smartlink®‘s Hub comprises of an Earth station communicating over a New Skies NSS6 satellite, to provide end-to-end IP communication to a large number of Terminals. The Hub provides control and monitoring functions for all transmit and receive operations. It generates control and timing signals for the operation of the remote stations, receives the remote return signals, and provides accounting functions and interactive services.
The Hub transmits the forward satellite Digital Video Broadcast (DVB) uplink, user data and control timing signals needed for the operation of remote terminals. The link supporting communication between the Remote terminals and the hub called Return Link and it uses MF-TDMA (Multi Frequency Time Division Multiple Access). It allows data rates from 144kbps to 2048kbps.
