Which system relays digital information instead of voice transmissions and can display the address of the call and routing information?

• A. Mobile data computers
• B. Landline phones
• C. Pagers
• D. Satellite radios

Answer: (A)

Relaying digital information rather than voice is about using data systems that push dispatch details straight to the unit. The onboard mobile data computer is designed for this. It connects to the computer-aided dispatch system and displays the exact call address, routing instructions, and often patient data and run details. That means responders can see where to go and how to get there, with directions and updates, without relying on voice radio chatter.

Landline phones carry voice, not the structured digital dispatch data. Pagers do carry digital messages, but they’re limited and typically don’t provide the full call address and real-time routing information displayed at the unit. Satellite radios focus on audio transmission and don’t deliver the integrated digital dispatch data needed for precise routing.
