Radio over IP (RoIP) is a new technology developed to replace expensive analog or digital Leased Telco lines used in radio systems with existing or inexpensive Data networks (WAN, LAN, Intranet, Internet). RoIP uses existing computer network or the internet to transport voice packets to and from their destinations. RoIP uses a modified format of Voice over IP (VoIP) which incorporates all of the control issues that are required to control a radio remotely (TX Audio, RX Audio, PTT, COS, & simple control bits for Aux functions).

MCRoIP Quadra Radio Bridge The MCRoIP (Multi-Channel Radio over IP) Quadra Radio Bridge offers 4 independent voice channels (4 radios to 4 destinations), easy configuration and monitoring over the web, telnet or RS232. MCRoIP has voice algorithms available from 5.3 to 64 kbps to fit every bandwidth requirement. Also includes a "true" RS232 bridge connection.

Raytheon NXU-2, network extension unit, is a single voice channel RoIP unit with 5 voice algorithms, a serial port and two control bits. It has an easy to use web interface but can also be configured via telnet & serial connections.

Vega IP-223 is a Dual channel RoIP that has a fixed voice compression & must be used in conjunction with the IP 1616 or C-6200 radio consols from Vega. The IP-232 offers remote configuration with a web browser.

Multitech offers VoIP solutions to radio applications. This equipment is a cost effect way to create a phone & radio solution to a location but does not offer all of the benefits of a dedicated radio interface.
