What is meant by the term "trunking" in communication systems?

1. Sharing one frequency across multiple systems

2. Limiting frequency to a single agency

3. Connecting different communication infrastructures

4. Using a fixed frequency for all communications

The correct answer is: Sharing one frequency across multiple systems

The term "trunking" in communication systems refers to the practice of sharing a single frequency or a set of frequencies across multiple communication channels or systems. This approach allows for more efficient use of limited radio spectrum resources by dynamically allocating frequencies to users as needed, rather than assigning a specific frequency to each user or agency. In a trunked system, when one user is finished communicating, their frequency becomes available for another user's call. This method is especially advantageous in environments where many users require access to communication channels but do not need them all at the same time. Trunking enhances capacity and efficiency, enabling smoother and more effective communication in emergency services and other critical operations.
