BK Technologies Corporation announced new features for InteropONE, the only PTToC ("Push To Talk Over Cellular") service that enables operational interoperability to first responders and individuals across the entire crisis management process through on-demand creation of user groups in five minutes or less. The new capabilities provide an enhanced interface for both the group owner and users, allowing for the handover of group ownership based on work shifts or command changes, and the ability to utilize private or group messages to share a location or any point on a map to facilitate situational awareness and team coordination, file attachments such as a person of interest photo, incident video, or a building floor plan, and web page links. The service also now utilizes iOS and Android notifications to provide InteropONE group members with real time activity alerts straight to their devices.
