Welcome message from the General Chairs

Satellite communications have renewed interest for their special potentialities in providing communications where terrestrial infrastructures are not present. Important questions to address concern the research areas for future satellite networks, support of mobility, new air interfaces, optimization of the design. Some answers to these important questions will be provided at the 2009 International Workshop on Satellite and Space Communications (IWSSC´09). This is the fifth year we are organizing this event and we are proud that its size increased over the years.
