What is Radio over IP

Radio over IP (Internet Protocol) – Definition

Radio over IP is a way of sending and receiving digital voice packets (audio, data) by way of an existing Internet Protocol (IP) infrastructure. Radio over IP gateways now enable two-way analog or digital transceivers to interface with both local and wide area networks. The benefits of using RoIP technology include lower costs, improved reliability and increased interoperability.

Ready to discuss your needs and ideas?

Radio over IP offers the most cost effective way to interconnect radio systems and operators together. Most businesses, military entities, public safety organizations and commercial operations already maintain their own private LAN or WAN. Additionally, there is an abundance of public IP networks that can be utilized with augmented private LAN’s. Consequently, there is no need to build out new communication pathways for deploying an RoIP solution in most circumstances.

Digitized voice packets that travel over IP networks can be easily routed to any type of radio system. You can now interconnect UHF, VHF, High Frequency radios with cell phones, VoIP phones and SIP enabled devices. This interoperability affords you improved voice communications as your organization moves closer to unified communications. Finally, interconnections between IP consoles and radios becomes much more reliable because they no longer rely on a single communication pathway.

How Does Radio over IP Work?

Radio over IP (Internet Protocol) is the process of sending and receiving radio transmissions using the Internet. It takes advantage of existing data networking protocols such as TCP/IP for reliability, UDP/IP for voice data transmissions, multicast networks that allow for routing data to multiple points, and unicast networks when applicable. Vocoders are used to convert analog voice signals into digital voice packets prior to transmission over IP networks. Routers and firewalls are used to secure a client’s network and the digital voice packets. Secure communications leverage advanced encryption technologies. Orion Systems uses 600 Ω (ohm) balanced circuits and will evaluate a client’s primary network for improved deliverability of data packets.

How Orion Connects Your Digital Radios to Incoming Calls

The Orion Radio Internet Protocol is a remote radio analog interface and control unit. The RoIP-8 interfaces to Orion Switch equipment by means of a Local Area Network (LAN) or Wide Area Network (WAN) connection utilizing Radio / Voice over Internet Protocol (VoIP).

Our IP Radio systems are extremely flexible and scalable to fit your needs as you grow. These remote radio analog interface and control units can connect 2 to 8 radios in a single unit. Often clients have us configure stackable solutions for a command center and smaller units for mobile control centers. Each radio interface consists of 600 Ω balanced analog transmit and receive audio pair, a solid state contact closure for radio keying, and a RS232 or parallel interface for radio control. The RoIP-8 performs an analog to VoIP/RoIP conversion of radio audio, and converts IP messages into radio key and serial control messages.
