Quick Detail:

Description:
The Cross-Network Gateway RoIP-102M is to convert the audio and PTT signals in a radio terminal into IP packets and then transmit the data via the IP networks. Generally, the radio range is limited by the restricted transmitting power, antenna sensitivity and other environmental factors. RoIP technology is developed to solve those problems and insure that the audio is transmitted in real time and the PTT signals are transmitted immediately and reliably, making the long distance voice communication across multiple networks possible.
What is RoIP (Radio over IP)?
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. RoIP technology is developed to solve those problems and insure that the audio is transmitted in
real time and the PTT signals are transmitted immediately and reliably, making the long distance voice communication
across multiple networks possible.
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 Need the 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.
