Some time ago, I was working on a project on the third floor of an office building. Space was scarce, so about 10 of us were sitting together in one big room. To avoid big company politics, our team set up it’s own wireless network which worked quite well with the open space we had. We used it for access to our source code repository and wiki, but since our team was distributed between the Netherlands and India, it was also used to access our Scrum tool.
