During an emergency, first responders need timely and relevant data to make informed decisions. Land Mobile Radio networks are intended for voice communications and do not have the capacity to transmit large amounts of data. Commercial cellular networks can become overloaded or fail completely, as the network becomes saturated by public use. This leaves public safety agencies competing for the same network resources when trying to transmit their mission-critical information, especially video.
