RoIP Systems
Radio Over Internet Protocol (Radio Over IP or RoIP) is a method of
communication that interconnects standard two-way radios with an IP network
such as the public Internet. RoIP introduces the ability to allow radios to
communicate directly with Voice Over Internet Protocol (VoIP) phones, analog
telephone adapters (ATAs) and even the ability to interface with the Public
Switched Telephone Network (PSTN). This connectivity with the PSTN allows
radios to communicate with cellular phones as well as landline telephones
anywhere in the world. This technology has far reaching applications from
transportation systems to emergency services to military use.
In its simplest form, a Radio Over IP system converts a radio signal to digital
data suitable for transport over an IP network and vice versa. A RoIP network
consists of some number of radios, which could consist of a combination of
handheld, mobile, and fixed two-way radios along with a gateway device that
provides the interface to an IP network.
Radio Over IP offers numerous advantages to both existing radio networks as
well as newly implemented communications systems. One example of these
advantages is the ability to extend the range of an existing radio network to
anywhere where access to the public Internet is available. By using any number
of available VoIP service providers that interface with the PSTN, the radio
network can connect to a cellular or landline telephone thus extending the
range of the network to anywhere in the world. Another advantage that Radio
Over IP provides is interoperability between differing radio networks. By
providing a common interface between the different networks, RoIP allows two
RoIP gateway devices to communicate with each other directly using the Internet
Protocol regardless of what type of radio networks the gateways are associated
with.
VOCAL's robust and comprehensive suite of software libraries provide the foundation for our RoIP Systems and
allow us to provide a complete RoIP solution across a wide variety of platforms. Our VoIP suite is fully integrated
and highly configurable, including a Network Stack, SIP Stack,
full-featured Telephony software, as well as a wide range of VoIP vocoders.
Together with SRTP, SDES, IPsec, and our
encryption libraries, VOCAL's VoIP software can ensure privacy and security of all communications.
