What is a primary benefit of using digital radio transmission?

The primary benefit of using digital radio transmission is greater clarity and less noise. Digital signals are less susceptible to interference compared to analog signals. This means that when a digital signal is transmitted, it retains its quality over longer distances and through obstacles that might distort analog signals. The encoding of audio and data into a digital format allows for advanced error correction techniques that further enhance the clarity of the communication.

In contrast, although lower cost of equipment, faster physical connections, and longer battery life can be important factors in certain applications, they are not the defining advantages brought specifically by digital radio transmission. Many digital systems can be more efficient, leading to better battery life, but their primary strength is in delivering clearer audio and data with reduced noise interference.
