The New Military PDA—that’s Personal Digital Alert system

The National Geospatial-Intelligence Agency (NGA) envisions one day deploying a system whereby a soldier deployed in a forward position or in special ops can download satellite imagery or upload images taken in the field using their PDA. Then here’s where it really gets interesting, the soldier can "use the PDA to set up a 24-hour, 5-kilometer geo-protection cylinder around your location with a 30,000 foot ceiling. You select the option to be notified of Red or Blue forces, that is friend or foes, over your flight. NGA watches the world for you." You can read about this in the NGA’s latest newsletter. I can just envision the next thing in person protection. A PDA from ADT or Brinks?—We watch the crime in your neighborhood for you and set up a perimeter when crime waves approach.
