I am not sure if any of you have been in Large Datacenters such as Terremark ( now verizon ) or someplace such as Equinix @ 350 Cermak in Chicago but these buildings are designed in such a way that they make cell use very difficult. Add on top of that the electrical noise from a few thousand computers and you have a good cell phone block.
It seems to keep the staff on task not checking FB every 30 seconds. Or looking for the most recent cat picture on instragram.
If it was legal to have a cell jammer in my office building I would have one sent next day.
