Shenzhen DBL Technology Limited  

Product Name: DBL Cross-Network RoIP VoIP Gateway RoIP-302m (Radio Repeater) Model NO.: RoIP-302M Type: Gateway Trademark: DBL Transport Package: Packing Box Dimension: 35.5*21.5*7 Origin: Shenzhen Product Description Cross-Network Gateway RoIP-302 The fundamental of RoIP(Radio overIP)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.
