Description:
?
3-PPT Port with GSM Module Cross-Network Gateway RoIP302M 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.
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.
