Pavement radio is a special radio communication system that is installed under the road pavement. It allows people to communicate with each other through a speaker and microphone that are connected to the pavement radio system.
Imagine a road as a long, flat sandwich with different layers. One of these layers is called the pavement layer, which is the hard surface we drive and walk on. Pavement radio is installed inside this layer so that it is protected from damage and weather.
When you talk into the microphone of the pavement radio, your voice goes through a special wire that runs underneath the pavement. This wire carries your message to the other person's pavement radio, which plays your voice through a speaker. It's like having a secret tunnel under the road that connects you with someone else on the other side.
Pavement radio is used by emergency responders like police, firefighters, and paramedics to communicate quickly and effectively during emergencies. For example, if there's a car accident, a police officer can talk to the other officers and emergency services using pavement radio to coordinate the response.
In summary, pavement radio is a communication system installed under the road pavement that allows people to talk to each other through a speaker and microphone. It's used by emergency responders to coordinate their actions during emergencies.
