Emergency Response Communications (ECS) is a system primarily used to facilitate emergency information communication between individuals and groups of individuals in one direction and two directions. Emergency response communications are typically designed to deliver information across multiple device types, from semaphores to text messaging to real-time streaming video, to form an integrated emergency communication system to optimize emergency communication. Unlike emergency notification systems, which typically distribute emergency messages in one direction, emergency respponse communication systems can initiate and receive messages between multiple parties. Emergency response communications systems typically consist of input devices, sensors, and output/communication devices. Thus, information sources can come from multiple sources and locations, and the wireless LTE private network system provides this information to one or more target groups in disaster relief, public safety, subway tunnel, maritime, etc.
