The 450 MHz frequency band is a globally active mobile radio spectrum with tremendous building penetration down into basements and an especially high range of up to 50 kilometres. The network enables operators of critical infrastructures to communicate via an independent platform that is not used by the wider public. This offers considerable advantages:

• Significantly higher availability, as the communication paths cannot be negatively influenced by other users (for instance at major events)
• Self-contained buffering of the radio cell to ensure communication capabilities even in the event of a voltage drop
• Encryptions and secure login scenarios enhance the security level
• The network is optimal for transmitting smaller data packets, e.g. control commands
• A high number of stations can be connected
• Free choice of transmission protocol thanks to PPP-linking
• Further services can also be used in parallel

This allows system operators, providers and public utilities to handle demanding communication and automation applications over the 450 MHz frequency.

The FW-5-GATE-450 brings together powerful telecontrol with a 450 MHz CDMA module for flexible mobile phone connection. With its dual antenna, the radio module provides a link to control and energy management systems with high availability. The downlink and uplink speeds of the module and network are optimal for transmitting switching commands and for ensuring smooth communication. The bay station controller comes with convenient performance reserves, also in respect to future challenges.

Application areas

• Substation and bay station controllers in secondary unit substations and medium voltage switching stations
• Controllers for distribution network automation and feed-in management in accordance with the Renewable Energy Law
• Monitoring and control device for utilities and waste disposal as well as industry
• Data acquisition and communication system or protocol converter in transport and infrastructure applications
