Overview

SIST EN 300 197 V1.4.1:2003 defines the minimum performance parameters for fixed point-to-point radio systems transmitting digital signals in the 38 GHz frequency band. This European standard, adopted by the Slovenski inštitut za standardizacijo (SIST), ensures compatibility, performance, and regulatory compliance for microwave digital radio relay equipment operating between 37 GHz and 39.5 GHz. The document is fully harmonized with EN 300 197 Version 1.4.1 and produced under the auspices of ETSI’s Transmission and Multiplexing technical committee.

The standard is highly relevant for telecommunications operators, systems integrators, and equipment manufacturers deploying high-capacity digital radio links in local and regional networks, facilitating high-speed data transport using spectrum-efficient point-to-point technologies.

Key Topics

• Frequency Band and Channel Arrangements:
  Defines use of the 37–39.5 GHz frequency range for terrestrial fixed radio links. Channel spacing and arrangements are based on CEPT recommendations, supporting a variety of payload bitrates.

• Transmission Parameters:
  Covers system payload rates from 2 Mbit/s up to STM-1 (155 Mbit/s), addressing both Plesiochronous Digital Hierarchy (PDH) and Synchronous Digital Hierarchy (SDH) systems.

• Spectrum Mask and CW Components:
  Specifies the required spectrum masks to control out-of-band emissions and manage discrete continuous wave (CW) spectral components within designated limits, essential for minimizing interference.

• Spectral Efficiency Classes:
  Introduces multiple equipment classes based on modulation schemes:

  • Class 2: Typically 4-state modulation (e.g. 4-QAM)
  • Class 3: 8-state modulation (e.g. 8-PSK)
  • Class 4: 16/32-state modulation (e.g. 16-QAM)
  • Class 5: 64/128-state modulation (e.g. 64-QAM)
    These classes allow for adaptivity in implementing more spectrum-efficient or higher-capacity systems.

• Compatibility and Performance:
  Ensures system compatibility in terms of frequency, polarization, and channel arrangements. Outlines performance objectives following recognized ITU recommendations for error rates and availability.

• Environmental and EMC Requirements:
  Mandates operation within defined climatic and electromagnetic conditions, referencing applicable ETSI and IEC standards.

Applications

SIST EN 300 197 V1.4.1:2003 is essential for:

• Telecommunications Backbone and Access Networks:
  Facilitates the design and deployment of high-capacity digital microwave links as part of national and regional telecom infrastructures.

• Mobile Backhaul:
  Provides robust guidelines for radio links supporting cellular and 5G networks, where high throughput and strict electromagnetic compatibility are crucial.

• Enterprise and Government Data Networks:
  Enables secure and reliable point-to-point connections for mission-critical data in business campuses, data centers, and governmental operations.

• Urban and Suburban Broadband Expansion:
  Supports cost-effective wireless alternatives to fiber deployment in metropolitan environments where rapid rollout and scalability are needed.

Related Standards

Equipment and systems conforming to SIST EN 300 197 V1.4.1:2003 are typically used alongside the following standards:

• ETSI EN 300 833:
  Point-to-point antenna and feeder system characteristics for microwave radio systems.

• ETSI EN 301 126-1:
  Procedures and definitions for conformance testing of fixed radio equipment.

• ETSI EN 300 385:
  Electromagnetic compatibility standard for fixed radio links and ancillary equipment.

• IEC 60950:
  General safety requirements for telecom and IT equipment.

• ITU-T G.703, G.707, and G.783:
  Specifications for digital hierarchies and interfaces relevant to SDH and PDH systems.

• CEPT/ERC Recommendation 74-01:
  Defines regulatory limits for spurious emissions on fixed radio systems.

These related standards help ensure interoperability, safety, and regulatory compliance in all deployments of fixed point-to-point digital radio systems in the 38 GHz band.
