You don’t need numbers to know that radio communication saves lives.
Think of how vital radio communication is to the ship that’s sending out a distress call, or for the airplane experiencing technical issues, or for the first responders to a natural disaster. Or, what about people working in isolation in high-risk work environments, like corrections personnel, or a team of backcountry firefighters? A functional radio communications system can mean the difference between life and death. When time is of the essence and someone needs immediate medical attention, a radio carries the promise of a better outcome, so it is important to understand how they work and what they can and cannot do, and what rules govern the use of these systems.
