Overview

SIST EN 300 408 V1.3.1:2003 specifies key minimum requirements and operational parameters for fixed radio systems using point-to-point transmission in the 58 GHz frequency band. Developed by the Slovenski inštitut za standardizacijo (SIST), this European standard enables efficient use of the 57–59 GHz band, facilitating the transmission of both digital signals and analogue video signals without the need for coordinated frequency planning. The document introduces modifications to the 50 MHz spectrum mask, updates antenna requirements, and includes editorial enhancements to streamline the standard.

These radio systems leverage the high atmospheric attenuation characteristic of the 58 GHz band, which minimizes interference and supports spectrum sharing among diverse users, such as public and private networks. Compliance ensures interoperability, electromagnetic compatibility, and reliable service, supporting high-density applications as well as private connectivity needs.

Key Topics

• Frequency Band and Channel Arrangements

  • Utilizes the 57 GHz to 59 GHz band, with provisions for 50 MHz and 100 MHz channel spacings.
  • Covers both indoor and outdoor equipment environmental requirements.

• Equipment Classes

  • Class A: High Density Fixed Service (HDFS); intended for public networks and subject to rigorous channel selection procedures and availability/error-performance standards.
  • Class B: For private network connections, such as video surveillance; more relaxed performance criteria.

• RF-Channel Selection and Interference Avoidance

  • Mandatory RF channel selection for Class A to detect occupied channels and avoid disturbing existing links.
  • Interference thresholds and calibration guidance to ensure robust spectrum sharing.

• Spectrum Mask and Antenna Requirements

  • Defines new spectrum mask criteria for 50 MHz channels, facilitating cost-effective and efficient system design while maintaining spectrum efficiency.
  • Antenna radiation patterns and measurement interface standards are referenced, ensuring consistent testing and performance.

• Transmitter and Receiver Parameters

  • Specifies limits for transmitter power, EIRP (Equivalent Isotropically Radiated Power), frequency tolerance, and spurious emissions control.
  • Adopts recognized international recommendations for error performance, compatibility, and safety.

Applications

This standard is crucial for organizations deploying fixed point-to-point radio systems where coordinated spectrum planning is impractical or unnecessary. Key applications include:

• High-density backhaul for mobile networks: Particularly for short-span interconnections (up to about 500 meters) between cellular base stations.
• Enterprise and private networks: Secure wireless links for private campuses, industrial sites, or video surveillance systems.
• Rapid network deployment: Temporary or permanent data links where fiber is unavailable or cost-prohibitive.
• Broadcast and media industries: Transmission of high-quality analogue video signals for events or temporary installations.

By adhering to the updated spectrum mask and antenna requirements, service providers and manufacturers can optimize system performance, reduce interference risk, and ensure compliance with European regulatory frameworks.

1 Scope The present document specifies the minimum performance requirements for terrestrial fixed service radiocommunications equipment operating in the 58 GHz frequency band which do not require co-ordinated frequency planning. The frequency band is proposed to be used by various technologies for uncoordinated use of the band. It also benefits from the high and stable atmospheric attenuation which suppresses efficiently distant interferers (about 10 dB/km to 15 dB/km at sea level, refer to ITU-R Recommendation P.676 [17]). For the purposes of the present document two equipment classes are specified depending on the network requirements: - Class A: Digital equipment for High Density Fixed Service (HDFS) applications typically connected to public networks, which apply the RF-channel selection procedure (see clause 4.1.3), error performance and availability requirements (see clause 5.2). - Class B: Equipment without requirements for quality of service, typically private network connections. Typical applications for Class A equipment are e.g. interconnection between cellular networks where there, in some cases, is a need for short length connections (up to about 500 meters). The RF channel selection procedure shall be used to protect existing systems from a new system being commissioned. However, the channel selection procedure may not guarantee interference free installation or operation in all cases due to limitations in the procedure with respect to the variety of systems. Typical applications for Class B equipment are in private networks, such as video surveillance systems. This new version of this EN, introduces a different spectrum mask for systems designed for 50 MHz channel separation. While considered more convenient from the point of view of easy and cost effective design, the new mask is considered equivalent to the previous one from the point of view of spectrum efficient usage. Therefore, from the technical point of view, for compliance to article 3.2 of R&TTE Directive [19], systems that have already been assessed against the previous version of the present document should not be necessarily reassessed against this new version. The present document does not contain aspects related to test procedures and test conditions, however they are to be found in EN 301 126-1 [7]. Safety aspects are outside the mandate of ETSI and they will not be considered in the present document. However compliance to EN 60950 [18] will be required to comply with Directive 1999/5/EC [19]. Technical background for the parameters and requirements referred in the present document may be found in TR 101 036-1 [16]. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.
