The fundamental of RoIP(Radio over IP)technology is to convert the
audio and PTT signals in a radio terminal into IP packets and then
transmit the data via the IP networks. The challenge in this
technology is to insure that the audio is transmitted in real time
and the PPT control signal is transmitted immediately and reliably.
The radio range is general limited by the restricted transmitting
power, the antenna sensitivity, and other environmental factors.
The success deployment of this technology extends the coverage of a
radio network without using expensive repeaters or links up
multiple radio networks in the world. In addition, this technology
can also links up the radio world to the VoIP world and the
cellular world easily. It truly makes the voice communications
across multiple networks possibleRoIP302 series is developed based
on VoIP technology to realize RoIP functions in order to create a
new type of gateway to bridge voice communications across multiple
networks (Radio, Cellular, VoIP). Its main advantages are low
bandwidth usage, high fault tolerant, low loss in voice quality,
fast response, easy installation and configuration. It is ideal for
setting up a private network with multiple voice communication
platforms, a distributed network for remote management, a network
with extended coverage, and an integrated network of multiple
amateur radio networksRoIP302 Series Cross-Network Gateway has 3
PTT interfaces. Up to 3 audio channels from radio networks can be
connected to the RoIP302 simultaneously. All 3 channels can be
programmed into the same or different groups in order to bridge
real time voice communications to various network interfacesRoIP302
Series has a built-in GSM/CDMA cellular phone module, user can
access the radio networks connected via the cellular network
installed. A radio terminal equipped with DTMF generation
capability can make an outgoing call via the cellular network as
well
