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.
- Increase the number of channels on an existing network. VoIP enabled radios support multiple data streams for both voice and data communications over a physical RF link.
- Use VoIP services. VoIP enabled radios can connect with the Internet and access service providers to communicate directly with mobile devices or landline telephones.
- Interoperability with other networks. VoIP enabled radios can communicate with each other directly over the Internet and to other radios via an VoIP gateway.
