Challenge: A Unified Communication Network for Water Infrastructure and Security
Brněnské vodárny a kanalizace (BVK) needed a communication solution for:
- Water distribution monitoring
- Remote telemetry
- Security system communication
Traditionally, such requirements demand separate networks, increasing cost and complexity. BVK wanted a solution capable of merging all applications into a single, reliable RF system.
Key technical requirements included:
- Support for Siemens Simatic S7 and Siemens 95U
- Compatibility with MARS-A and Siemens 3964R protocols
- Combined polling and report-by-exception operation
- Operation on one 400 MHz simplex channel, 25 kHz
- Coverage for 100+ remote sites
Solution: MORSE with MR400 – Multi-Application Capability on One Frequency
The MORSE system with MR400 radio modems enabled BVK to run several fully independent applications on a single RF channel – without interference or performance degradation.
Why MORSE was chosen:
- Proven stability in 400 MHz band
- Efficient anti-collision mechanisms allowing mixed traffic
- Flexible interface options for Siemens RTUs
- Ability to run telemetry and security data concurrently
- Remote supervision via the Internet
The network also supports both traditional polling and fast report-by-exception for alarm conditions.
Results: One Network, Multiple Applications, Major Cost Savings
The MORSE network now provides BVK with:
- Reliable communication for SCADA, telemetry and security
- Significant cost reductions by eliminating the need for a separate security network
- Centralised remote supervision directly from RACOM headquarters
- Stable operation across all 100+ sites
MORSE proves that even complex multi-application environments can operate seamlessly on a single shared frequency – delivering efficiency, reliability and long-term value.
