During severe weather events or local emergencies, broadcast television remains one of the most resilient forms of communication. Cell towers can become overloaded or lose power, but broadcast signals often continue to transmit. By ensuring that citizens can accurately locate and receive these signals, DTV.gov maps contribute to the resilience of the national communications infrastructure. They help ensure that when the internet fails, the public can still tune into vital emergency broadcasts.
