ROIP enables radios and non-radio devices to communicate over IP.

• A. It enables radios and non-radio devices to communicate over IP
• B. It is a satellite radio protocol
• C. It only works on LANs
• D. It requires a dedicated fiber link

Answer: (A)

Radio over IP carries radio voice and signaling over standard IP networks by digitizing the radio audio and transmitting it as IP packets. This lets radios talk to devices that aren’t radios (like computers or IP phones) using the same network infrastructure, so interoperability and centralized control become possible across local and wide networks. The best choice matches this purpose exactly: ROIP enables radios and non-radio devices to communicate over IP. It isn’t a satellite radio protocol, and it isn’t limited to LANs or require a dedicated fiber link—ROIP works over any IP network with appropriate quality of service and network planning.
