In the WWLAN
projects three application scenarios have been identified and studies. In these scenarios the potential offered by broadband multisegment networks are effectively used:
- railway scenario: the broadband multisegment network (satellite + WLAN) is used to offer seamless and highly satisfactory multimedia services (Internet, Digital TV,…) on ETR trains and in railway stations;
- “crisis area” scenario: the broadband multisegment network is used to offer effective support to communications among the firefighter’s fixed stations, the vehicles and the officers involved in the rescue operations;
- “urban and industrial area” scenario: the broadband multisegment network is used as a backbone for the interconnection of wireless local area networks and for the connection of these to the internet. The scenario consists in the realization, in the urban/industrial area involved in the service, of a cellular coverage: each cell is served by a radiobase directly connected to a satellite gateway by means of a fixed line or, indirectly, by means of a point-to-point, possible multi-hop, radio link.
For each of the above scenarios, the most suitable architectures have been analyzed, and output specifications have been given for the field deployment of the studied solutions.
