Open Standard

Open Standard

At Federal Radio, we believe strongly in providing our customers with choices. 

FedSMR-D2 uses DMR Tier III open standard because it combines the capacity and intelligence of a networked trunked radio network with the essential advantages of an open, non-proprietary specification:  

1. Interoperability and Vendor Choice

  • Multi-Vendor Support: Because DMR Tier III is an open standard defined by ETSI, organizations are not locked into a single supplier. Radios and infrastructure from different manufacturers can be designed to interoperate seamlessly, ensuring healthy market competition.  
  • Security of Supply: The widespread adoption by multiple vendors guarantees the long-term availability of equipment and accessories, protecting your investment over the system’s life cycle.

2. Efficiency and Capacity

  • Trunking and Dynamic Channel Allocation: Tier III utilizes control channel trunking technology, which automatically and dynamically allocates channels to users as needed. This maximizes spectrum efficiency and significantly reduces user wait times, providing reliable communication for thousands of users.  
  • Doubled Capacity: Like all DMR tiers, Tier III uses two-slot Time Division Multiple Access (TDMA) within a single 12.5 kHz channel, effectively doubling the capacity without requiring additional frequencies.  

3. Advanced Features and Scalability

  • IP-Based Architecture: The systems are built on an IP-based infrastructure, allowing for easy multi-site connectivity and wide-area coverage with seamless roaming for users.  
  • Data and Applications: Tier III supports integrated voice and data services, including:
    • GPS/Location Services for real-time tracking of personnel and assets.  
    • SCADA and Telemetry for reliable transport of critical control data.
    • Advanced Safety Features like emergency calling, priority interrupt, and Man-Down alerts.  
  • Scalability: The system architecture is inherently scalable, allowing organizations to start small and easily add capacity and redundancy as the user base or coverage area grows.  
  • Interoperability: Common interface devices are readily available to support connection to P25, MCX, POC, and other networks to support interoperability with local public safety systems

4. Reduced Total Cost of Ownership (TCO)

  • Lower Equipment Cost: Competition among manufacturers drives down the cost of radios and infrastructure compared to closed, proprietary systems
  • FedSMR-D2 subscribers pay nothing for the RF head-end, thus saving on implementation and maintenance costs for the life of the service..

Ease of Maintenance: Features like Over The Air Programming (OTAP) allow radios to be updated and reconfigured centrally, saving significant time and labor costs compared to manual, bench-top programming.
