3-PPT Port Cross-Network Gateway RoIP302 is developed based on the RoIP technology to bridge voice communications across multiple networks. It can connect up to 3 radio stations operated at different frequency bands simultaneously. These 3 radio stations can be configured in a single or multiple groups to communicate with another group which is defined in another RoIP device. This enables a very flexible configuration among various radio stations in order to form a single or multiple RoIP networks. With the built-in GSM and VoIP interfaces, RoIP-302 can also bridge voice communications among these networks.
