Overview

SIST ETS 300 393-2:1999 defines requirements for the air interface (AI) of Terrestrial Trunked Radio (TETRA) systems, focusing on the Packet Data Optimized (PDO) mode. This standard specifies protocols and procedures at the radio level to ensure reliable wireless packet data transmission in TETRA networks.

As a direct adoption of ETS 300 393-2 (Edition 2), this Slovenian standard updates the air interface specifications following the validation of the system design language (SDL) model. It addresses both physical and logical aspects of radio transmission, enhancing support for secure and efficient mobile communication in public safety, transportation, utilities, and industrial sectors.

Key Topics

• Radio Transmission Principles

  • Logical and physical channel definitions for TETRA PDO
  • Error control including coding, interleaving, and scrambling
  • Modulation schemes and timing structures
  • RF characteristics: output power, unwanted emissions, and tolerances

• Synchronization and Multiplexing

  • Synchronization between base station (BS) and mobile station (MS)
  • Time slot allocation and burst organization
  • Multiplexing strategies for efficient data throughput

• Receiver and Transmitter Performance

  • Blocking, spurious response, and intermodulation performance
  • Sensitivity and selectivity considerations
  • Performance metrics: vector error magnitude, bit error rates

• Radio Link Control

  • Power control methodologies
  • Path loss measurement and compensation
  • Radio link quality assessments

• Data Service Support

  • Compatibility with network layer protocols (ISO/IEC 8348, 8878, 8208)
  • Procedures for connection-oriented (CONS) and connectionless (CLNS) network services
  • Packet handling, addressing, and quality of service for mission-critical data

Applications

TETRA PDO air interface standardization delivers practical value by enabling:

• Mission-Critical Radio Networks:
  Reliable, low-latency packet data services for emergency response, law enforcement, and transport.

• Industrial and Utility Use:
  Efficient mobile data exchange supporting remote monitoring, outage recovery, and field force automation.

• Urban and Rural Coverage:
  Optimized RF and synchronization protocols ensure robust performance across varied environmental conditions.

• Interoperability and Future-Proofing:
  Harmonized protocol stacks simplify device integration and ensure compatibility with evolving TETRA equipment and infrastructure.

Organizations implementing or operating TETRA PDO systems depend on this air interface specification to achieve secure, scalable, and standards-compliant wireless data transmission.

Related Standards

For a comprehensive approach to TETRA and its air interface, consider these related standards:
