FOI's research on underwater communications was initially conducted for military purposes. Today, there are several driving forces behind research in this field. Now, wireless connections in water can also be used in civilian applications.
"In a research project, sponsored by the EU, an infrastructure of sensors is built at the sea floor," Erland Sangfelt, underwater expert at FOI, explains. "The object is to monitor environmental changes in the sea, receive advance warnings of earthquakes, follow underwater weather patterns and especially explore for oil and gas. Wireless communications has played an important role in these research areas."
Up to now, echoes have created problems in underwater communications. These echoes, which can be compared to an echo in a cathedral, have limited the data rate in underwater transmission. Researchers at FOI now have developed the technology further and discovered a way to reduce the effects of echoes. The research results are not secret and the technology could be employed already today.
"Here is a good chance for Swedish industry to utilize this technology in various products," Tommy
This Digital Communities white paper highlights discussions with IT officials in four counties that have adopted shared services models. Our aim was to learn about the obstacles these governments have faced when it comes to shared services and what it takes to overcome those roadblocks. We also spoke with several members of the IT industry who have thought long and hard about these issues. The paper offers some best practices for shared government-to-government services, but also points out challenges that government and industry still must overcome before this model gains widespread adoption.
