Abstract

This document provides guidelines and recommendations for the implementation of an Interaction Channel based on two way satellite links, to users connected to Satellite Master Antenna Television (SMATV) systems. The system provides the Interaction Channel through the concatenation of a Satellite section and a Coaxial section (see figure 1) in a seamless fashion. Guidelines and recommendations here provided are valid for the implementation of very cost effective solutions matched to the SMATV scenario as well as for the reuse of already operating satellite networks which are currently installed in a huge amount of buildings throughout Europe.
