包装清单：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.What is a Cross-Network Gateway?•It enables voice communications among the Radio, VoIP, GSM, and Public Announce (PA) networks. •It incorporates Radio over Internet Protocol (RoIP) which converts radio voice communications into VoIP. •It links up various radio networks together in order to extend the geographical coverage. •It is a GSM voice gateway by enabling voice communications to and from the telephone networks (GSM and PSTN) •It enables a voice connection to the public announce system for general and emergency broadcast. •It makes recording of voice communications among various networks simple and easy. Who needs a Cross-Network Gateway?•Radio Service Operators who would like to expands their geographical coverage. •Radio User who would like to make and receive calls from the telephone networks. •System administrators who would like to monitor and maintain good control over the existing radio networks. •System Integrator who would like to build or deploy a reliable voice communication network in timely manner.
