All data are sent back to a command center. The system, called the Advanced Ground Information System (AGIS), allows users of a dedicated network to view the identity, location, and status of all other users on the color display of a cell phone. The software works with over-the-counter pocket personal computers (PCs), laptops, tablets, and similar products. The AGIS software allows a variety of cell phones to be used in the same operational network. AGIS enables PCs with access to the Internet to join the AGIS network. The use of either high speed digital cellular or Wi-Fi enables users to rapidly exchange voice, text, photos, video, and other information. When establishing an event on the system, critical information related to the incident is entered, which creates its own information "bubble." When the track is selected by any of the users, they can access all of the entered information. The AGIS system may not be appropriate for routine, daily situations officers confront; however, when a major incident occurs, the ability to transmit and receive information while viewing a picture of the scene as it unfolds can be a critical tool.
