產品描述

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.
