ROIP Gateway (ROIP-4) 302

1. Radios repeater RoIP is used to link up the civilian radio network, internet, and cellular phone Network. Its operation and performance rely on the broadband network connections via Private and/or public networks and the cellular phone networks. Due to the stability and Reliability of these networks, this product may not be able to link up all the networks Connected without any interruptions. Therefore, it is not recommended to use this Product in an emergency system or a communication system with zero-failure.

2. This product can bridge and extend radio networks all over the world. Please consult your local regulations in order to use this product legally.

3. This product requires the use of dynamic DNS (DDNS) service. For testing purpose, this DDNS service is temporary provided for free by DBL Technology (Hong Kong). However, this service is not guaranteed without any interruptions. Customers are urged to build their own DDNS server or obtain this service from a DDNS provider. Free DDNS server software may be obtained freely from your local network service provider.

4. Customers and/or users are taking full responsibilities and all risks in using this product.

We are not responsible for any direct or indirect losses caused by, but not limited to communication failures as a result of product failure or network problems.

Radio Cross-Network Gateway RoIP-302 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 wellRoIP302 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 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 networks 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 possible.
