Satellite extension of xDSL copper wire based networks – ESA CSC: Connectivity & Secure Communications

Objectives

The study objectives are to:

Define the impacts on the current architecture of xDSL and satellite networks of such an integration,
Define the corresponding modes of operations and specific protocols to be put in place,
Propose a preliminary design and cost of a satellite network addressing this type of network ,including the need for signalling,
Identify the potential impact on the value chain and in the overall telecommunications market of such an approach,
Identify the benefits of using satellite user terminals in conjunction with xDSL user terminals (in particular on the cost for users, service delivery and installation),
Identify the benefits of this approach with respect to terrestrial-only solutions or satellite-only solutions,
Propose a road map for any technology development, validation, early introduction (with existing satellite networks) and full scale deployment (with dedicated satellite capacity) of such a network solution.

Challenges

Key issues addressed by the study include the size of the addressable market, if and how it is possible to reallocate the downstream xDSL bandwidth that is freed up by the use of the satellite channel to improve the upstream performance of the xDSL lines involved, and how the system should be designed to enable it to be incorporated easily in existing xDSL networks and managed using existing operations support and business support systems.
