You place it and it gives you a UAV like sweep on your map in a large radius of the area you placed it. All team mates can see the sweep on their map too. If you have a few people place them at key locations you can really benefit as a team and you can actually do away with the UAV perk all together.

In hardcore, you have to contantly be checking your map with the portable radar, which I do anyways. If you don't frequently check the map, every 10 seconds or so, it won't be of much help.
