The soldiers can use the smartphones to send texts of GPS coordinates, file reports directly from the handset, or use the camera to take pictures of surroundings. With no special software used, these models could not be made secure enough for overseas operations although the Army is considering using the phones in connection with other radios to help encrypt transmissions. In sensitive areas, the Army is planning on using "cell towers in a suitcase", similar to femtocells, to ensure signal strength in certain areas.
Army program director Ed Mazzanti says that they will be selecting two mobile operating systems to deploy later this year. This way they can minimize the need for software development while still offering variety. Mazzanti says that so far the Apple iPhone and Android have been "well received".
