there are many existing cluster intercom systems, including analog clusters, tetra digital clusters, and gota digital clusters. information islands are formed between clusters of different systems and cannot be interconnected and interoperable. various clusters and commonly-used communications such as pstn, ip telephony, and gsm/4g, etc. the internet also cannot achieve interconnection and intercommunication. in the field of emergency dispatch and command applications, information silos are the biggest obstacle to the effectiveness of the work. the integration of cluster intercom networks with traditional telephone communication networks and ngn networks is imperative. mingdao cluster gateway is a new cluster gateway device designed to meet this demand.
1. in this scenario, a gsm/4g radio cluster gateway is deployed next to the radio station and connected to the radio via a radio link.
2. the operator applies for a gsm/4g network sim card and inserts a gsm/4g radio cluster gateway.
3. the dispatch center simply dials the number of the sim card to communicate with the radio and the handset under the radio.
program advantages:
1. the deployment is simple and quick: just insert a sim card to realize the interconnection between the remote control center and the radio station.
2. to expand communication distance: the communication distance of general radio stations is several kilometers to several tens of kilometers. through the gsm/4g radio cluster gateway, the transmission distance can be improved throughout the country, which greatly increases the communication distance.
3. realize the interconnection and intercommunication with other telephone terminals: through gsm/4g radio cluster gateways, radio stations have access to mobile telephone networks, which can be interconnected with ordinary fixed telephones and mobile phones.
1. in this scenario, deploy a voip radio cluster gateway next to the radio and connect to the radio via a radio link.
2. assign an intranet or public ip to the voip radio cluster gateway and connect the voip radio cluster gateway to the corporate lan.
3. the dispatch center or other terminal can send the call to the voip radio cluster gateway through the internet/vpn network to communicate with the radio and the handset under the radio.
program advantages:
1. the deployment is simple and quick: just connect the voip radio cluster gateway to the internet to realize the interconnection between the remote control center and the radio station.
2. expand communication distance: the communication distance of general radio stations is a few kilometers to several tens of kilometers. through the voip radio cluster gateway, the transmission distance can be increased nationwide or globally, which greatly increases the communication distance.
3. realize interconnection and intercommunication with other telephone terminals: through voip radio cluster gateways, radio stations can interconnect with sip terminals, fixed telephones, and mobile phones.
