Abstract: An officer communication system and method for providing a peer-to-peer mobile and wireless network software architecture which allows mobile units or clients, administrators, and/or dispatchers to communicate information that is pertinent to law enforcement, or related services. Such information includes text, images and/or audio. For example, such information can be indicative of an officer's or suspect's location (e.g., latitude, longitude, altitude, or intersection), speed and direction of travel, an officer's assignment details, national or local bulletins, the homeland security alert level, a “live” video feed, maps or directions, etc. In one embodiment, the system via a client user interface allows for the automatic readout of intersections during a chase, and the marking on maps of special locations (e.g. locations where evidence can be found).
