Telecommunicator State Practice Exam

Two-way radio enables real-time voice communication between mobile units and a dispatcher, allowing direct conversation rather than just sending signals. In Bayonne, New Jersey, the first two-way police radio system went into use in 1933, marking a milestone where patrol cars could talk directly with the central dispatch and with each other. That milestone is why 1933 is the best answer—it reflects the earliest adoption of interactive, two-way voice communication for public safety in that city. The earlier date is not tied to Bayonne’s implementation, and the later years occurred after this notable development in police radio history. Understanding this helps you see how dispatch technologies evolved from one-way signaling to real-time two-way conversations.
