RoIP | Radio over IP Software Engine

RoIP is the integration of VoIP technology in two-way Push-to Talk radio

RoIP can be deployed over private networks as well as the public Internet.

RoIP Engine

RoIP (Radio-Over-Internet Protocol) is the integration of VoIP technology in two-way radio  networks. Adaptive Digital’s RoIP Software Engine enables users to extend their radio connectivity beyond their local network to any device and to anywhere across the globe.

Radio over IP can be deployed over private networks as well as the public Internet.


Half or full-duplex operation under a wide dynamic range of audio levels, even when the microphone input signal is weak

Configurable VOX (VAD) or Push-To-Talk (PTT) operation to start a RoIP transmission

Squelch/Busy Output to indicate RoIP reception


SRTP (Secure RTP) / AES Encryption

G.711 Appendix 1 (Packet Loss Concealment)

G.711 Appendix 2 (Voice Activity Detector / Comfort Noise Generator)




Adjustable packet size: the engine supports configurable packetization time (10, 20, 30, and 60 msec) in 10 msec increments. The packet size follows from the codec and packet interval.

Automatic Gain Control / Mute


DTMF, MFR1, MFR2 Detection and Generation

Call Progress Detection and Generation

Arbitrary Tone Detection

Conference Server/Bridge

Play/Record of Audio Files

API support (management, event monitoring/reporting, statistics)


RoIP Applications:

Interoperability Gateways

Radio Dispatch Systems (military, first responders, transportation, etc.)

In a Radio over IP application, at least one node of a network is a radio (or a radio with an IP interface device) connected via IP to other nodes in the radio network. The other nodes can be two-way

radios, but could also be dispatch consoles either traditional (hardware) or modern (software on a PC), POTS telephones, softphone applications. or some other communications device accessible over IP.


Beyond Line-of-Sight (BLOS) is a radio communications capability that links personnel or systems too far or too obstructed by terrain for Line of Sight (LOS) communications.

Improved reliability.

Increased interoperability between different systems

Generally, RoIP systems use a sample rate of 8000 samples per second and single channel (mono) audio.

RoIP from a system point of view, is essentially VoIP with Push To Talk (PTT).

Radio over IP is useful in land mobile radio systems used by defense departments, public safety departments and fleets of utilities spread over a broad geographic area. 

Economical and reliable distant radio links in the field across large geographies, such as those needed by military units, state troopers, energy utilities, and emergency transportation vehicles are well served by RoIP technology.
