III. Overview
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 PTT 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 link up the radio
world to the VoIP world and the cellular world easily.It truly makes voice communications across
multiple networks possible.
RoIP 102 basic version is a more compact, more practical high-tech multiple network
(Radio,Cellular,VoIP) equipment,which access to a group,no GSM module,simply complete the
radio voice signals into IP signals,access to the Professdional Edition or Stardard Edition RoIP
302M group,to achieve the client and the central station intercom communication.Also has a remote
control switch interface,which enables remote control.
RoIP102 gateway can be installed in IP networks with intranet or internet connections via
ADSL modem,Cable modem,or Local Area Network (LAN). The unique built-in DDNS client can
help to simplify the installation and configuration without relying on a voice relay server in order to
achieve interconnections among RoIP Series gateways.
