RoIP Gateway - Radio over IP Gateway
VOCAL’s RoIP Gateway enables interoperation of different radio systems over IP networks

VOCAL’s RoIP Gateway Solutions are a complete communications solution for interconnecting different radio systems over IP networks. Our gateway designs provide cost effective links between radio networks in remote areas where long distances, difficult terrain or other conditions make continuous line of sight communications cost prohibitive. Contact us to discuss your radio over IP application.

VOCAL’s RoIP ANSI C software libraries are optimized for performance and support leading architectures from TI, ADI, ARM, Intel and other vendors. Our RoIP Gateway Reference Design may be licensed as a complete turn key system with custom solutions available to meet your specific requirements.

Radio Over IP Gateway Reference Design

VOCAL’s RoIP Gateway reference design enables rapid development of networked RF applications using IP protocols. Our RoIP solution is compatible with various radio standards and supports both full-duplex and half-duplex RF. The RoIP gateway radio controller interfaces with the local radio unit to transmit and receive RF signals on the local radio network. The radio controller supports full and half-duplex radio communications as well as PTT and other radio controls. The media processor sends and receives digital radio packets over an IP network.

VOCAL’s RoIP Gateway supports full and half-duplex RF communications using radio over IP networks

VOCAL’s RoIP software provides application developers a highly configurable framework with a network stack, jitter control, RTP, and other networking protocols. In addition, our software provides a wide range of voice compression algorithms including MELPe, G.711, G.722, Speex, etc. as well as robust echo cancellation and noise reduction algorithms. When combined with SRTP, SDES, IPsec and encryption, VOCAL’s comprehensive RoIP software can ensure secure communications with superior voice quality in the most challenging of environments.

What is EUROCAE ED-137?

The European Organization for Civil Aviation Equipment (EUROCAE) has defined the ED-137 standards for air-ground and ground-ground communications.  This allows end users to select products adhering to these standards from different vendors, instead of relying on single sourced custom solutions. With ED-137, they can still be confident of meeting operational and interoperability requirements. VOCAL’s RoIP software can be deployed with EUROCAE ED-137 support. In fact, ED-137 can be used for many use cases, not just those involving Air Traffic Management (ATM).  We have deployed ED-137 for a variety of uses, including those that do not include radio, but are still Push-to-Talk type systems.  Give our engineers a call to discuss your ED-137 needs.
