VoIP Radio Features


VoIP Radio Communications

VoIP Radio is a method of communications that enables digital two-way radios to interconnect using Voice over IP protocols over radio, satellite (Iridium, etc) and other networks. A VoIP enabled radio converts voiceband audio to digital data suitable for transport over an IP network. VoIP radio enables point-to-point and multi-point voice and data communications over existing RF channels. This technology offers numerous advantages to both existing radio networks as well as new communications systems under development.

VoIP Radio Software

VOCAL VoIP radio software provides application developers a highly configurable multi-channel framework with VoIP stack, jitter control, RTP, along with other networking protocols. In addition, our full-featured Voice Quality Enhancement 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 radio software provides a comprehensive digital radio solution that can ensure secure communications with superior voice quality in the most challenging of environments.

VoIP Radio Reference Design

VOCAL VoIP radio reference design is compatible with various mesh radio standards including Zigbee and 802.11s. It supports both full-duplex and half-duplex digital radio communications. Our 2-way digital radio design enables rapid development of RF applications with support for point-to-point and multi-point communications using Voice over IP. An enhanced software scan mode provides prioritized monitoring of selected VoIP channels and mixing of multiple data streams with combined audio output. Our RDK provides a customizable, fully-functional hardware and software solution including:
