Emergency frequencies are specific radio frequencies designated for urgent communication during emergencies. These frequencies are used by various services, including police, fire departments, and ambulance services, to coordinate responses and share critical information quickly. In many countries, emergency frequencies are standardized, allowing different agencies to communicate effectively. For example, in the United States, the Federal Communications Commission (FCC) allocates certain frequencies for emergency use, ensuring that responders can connect even in challenging situations. This system helps save lives by facilitating timely assistance and resource deployment.
