The scope of the ARTES 5.2 activity BeamSat is to prepare the groundwork and mitigate the risk and challenges for the development of a Ka-band satellite broadband access solution that will support high-rate broadband access to regions deprived from competitive terrestrial broadband solutions.
The main driver for this development will be the broadband market requirement and the move to Ka-band multi-spotbeam satellite technology instead of Ku-band transponders, which makes more satellite bandwidth available for broadband applications and at a significant lower cost.
Because of the available broadband capacity and performance improvements, BeamSat will also be able to support various value added services (VAS) for the consumer market: interactive television, video-on-demand, VoIP and other real-time (gaming) applications; and other professional services such as contribution and backhauling. These values added services will allow the network operator to differentiate himself on the market and run a successful network.
The main goals of the ARTES 5.2 BeamSat project are:
The key issues are:
The goal of the ARTES 5.2 activity BeamSat is to perform the required research activities, assess the feasibilities and mitigate the risk for the development of a Ka-band satellite broadband access solution.
The final goal of the entire BeamSat project (ARTES 5.2 & ARTES 3-4) is to accelerate Newtec’s growth within the broadband market and become the major European Broadband supplier next to the American competitors.
The broadband solution of the bidirectional Ka-band satellite broadband access network (to be developed in the BeamSat project) consists of:
The features are:
All of this will be developed and deployed following a gradual roadmap.
The project plan consists of two phases:
The project will maintain a heartbeat of 6 months, e.g. stage Ia, Ib, Ic, etc. This allows for a pragmatic development in accordance with the market requirements.
The following topics have been investigated.
They allow to perform pre-distortion for higher order modulation modes (constellations above 32 APSK) with a better performance and a significantly reduced complexity
Research and prototyping of polarisation switching implementation for the ODU terminal product range.
They allow to perform pre-distortion for DTH modcods on linearized transponders with a better performance and a significantly reduced complexity
