The update of the swiss high-broadband development concept focusses on those areas without satisfying services around and above 1 Gbps which so far are not deployed in an economically viable manner. Here considerations for public subsidies come into account. WIK supports these by three studies: one about appropriate state fundung mechanisms, one about up-to-date NGA-technologies and their characteristicas and performance and one providing cost-modelling of investment and subsidy demand of different roll-out goals.
The cost modelling analyses 30 scenarios of different characteristics: These includes 1 and 4 fiber strand topologies in a Point-to-point (PTP) or Point-to-Multipoint (PtMP) manner, with splitters in central exchange locations or remotely in the field. The goal-bandwidth lasts from 0.5 to 10 Gbps. Shared use of Infrastructure can be taken into account. The technologies considered are VDSL Vectoring, G.fast, XG.fast, XGS.PON, Ethernet PtP und DOCSIS. By taking into account the endpoints with already existing sufficient services or neglecting these in a greenfield consideration we end up in 60 final result sheets of different characteristics, each desribing the investments and the subsidies required.
The study about up-to-date NGA-technologies and their characteristics deals with all relevant market available or comming up technologies in the access network, which use copper, fibre, coax or radio links. It describes their essential characteristics and performance regarding strengths and weaknesses, especially regarding transmission quality.
The state aid concept study starts with describing the Austrian governments approach and derives analogies to applying these the Swiss situation. It takes into account strength and weaknesses and lessons learned.
