In a TETRA over IP network

A gateway is seen as a Base Station

Gateways can be located anywhere in the network

GW subscribers, PABX subscribers, Dispatchers, etc... are
processed as radio subscribers
TETRA over IP provides several benefits
=> Tetra/PABX numbering scheme association,
=> Call forwarding between MS and external subscribers,
=> Group call from outside the TETRA network
=> Emergency call, pre-emption, call queuing available
IP DATA Gateway
Mail server
• Provides for IP Over Tetra
• Mobile internet
• IP address migration
• IP/ITSI management
• More than a “simple” client /
server : both way connection

Conclusion

TETRA over IP is a field proven architecture

TETRA over IP is an open platform for system
integration

TETRA over IP is the right combination of state of the
art mobile communication and computer technologies
