Advanced solutions for distance learning via satellite
Review articleOpen access

AbstractDistance learning has aroused more and more interest during the last few years due to the convergence of several factors, namely the growth of education as a key driver for socio-economic development, the remarkable step forward of telecommunication technology and the number of people involved in the education process itself (user basin).A major obstacle has resulted to be, in many cases, the cost factor induced by the telecom transmission cost which has often made the distance learning system non-viable. This consideration has directed people's attention to satellite systems which, due to their intrinsic peculiarities, well answer the most important requisites: wide coverage area, high geographical penetration, low unit cost when operating in broadcasting mode, mature technology and so affordable terminal receiving cost.In this direction an interactive solution is offered by SkyplexNet,1 an advanced satellite telecommunication platform based on innovative space technology and integrated with versatile network management functions.SkyplexNet well answers distance learning service requirements, providing an asymmetrical connection to the user, namely a high rate on the forward (receiving) link via satellite and a low rate on the return (interactive) one via a terrestrial modem: this paper describes the main functions of the system highlighting its operational characteristics as well as the tele-education application which allows the creation of new pedagogical education models.
