Which acronym stands for a private two-way, short-distance voice communications service?

• A. CBRS
• B. CMRS
• C. PMR
• D. VRF

Answer: (A)

The concept being tested is a dedicated on-site radio system used for immediate, two-way voice communication. A Private Mobile Radio serves exactly this purpose: it provides private, short-distance voice channels for a specific organization to coordinate staff, vehicles, or activities without routing through a public cellular network. That direct, on-site two-way communication is the hallmark of PMR. CBRS refers to the Citizens Broadband Radio Service, a spectrum-sharing framework in the 3.5 GHz band used to support private networks and other services—not specifically defined as a private two-way radio system. CMRS stands for Commercial Mobile Radio Service, which covers cellular networks提供to the general public, not private on-site communications. VRF is typically Virtual Routing and Forwarding in networking, not a voice communications service.
