Which type of system uses the same radio frequencies and allows all departments to access all channels?

• A. GPS - Global Positioning
• B. Simplex System
• C. Conventional radio system
• D. trunked radio system

Answer: (D)

Trunked radio systems manage a shared pool of frequencies and use a central control channel to assign channels on demand. This setup lets many departments access any channel as needed, with dynamic allocation and talkgroups that keep agencies organized while still using the same overall spectrum. It’s the efficiency and flexibility of sharing a common pool of frequencies that makes all departments able to reach all channels when required. A GPS system is unrelated to radio channel access, as it provides location data rather than voice communication. A simplex system uses a single frequency without centralized control or dynamic allocation, so it can’t efficiently support multiple agencies sharing channels. A conventional radio system assigns fixed channels to specific groups, limiting cross-department access and spectrum efficiency.
