Overview

SIST EN 303 687 V1.1.1:2023 is a harmonised European standard developed by the Slovenian Institute for Standardization (SIST), aligning with ETSI EN 303 687. This document presents the regulatory and technical framework for Wireless Access Systems including Radio Local Area Networks (WAS/RLAN) operating within the 6 GHz frequency band (5 945 MHz to 6 425 MHz). The standard is intended to facilitate harmonised access to radio spectrum for 6 GHz WAS/RLAN devices, supporting compliance with European regulatory decisions such as ECC Decision (20)01 and Commission Implementing Decision (EU) 2021/1067.

By defining equipment categories, technical characteristics, and test methods, SIST EN 303 687 V1.1.1:2023 enables manufacturers, network operators, and regulatory bodies to deploy and manage 6 GHz wireless technologies while ensuring fair spectrum usage and minimizing interference with other radio services.

Key Topics

• Technical requirements: The standard outlines essential technical parameters for 6 GHz WAS/RLAN equipment, including RF output power, power spectral density, transmitter and receiver unwanted emissions, and mechanical/electrical design.
• Equipment categories: Details are provided for different equipment types, such as Low Power Indoor (LPI) and Very Low Power (VLP) devices, ensuring appropriate operational requirements depending on intended usage scenarios.
• Conformance and testing methods: Clear methodologies for measurement and compliance are established, including environmental test conditions and step-by-step test sequences to ensure repeatability across laboratories.
• Spectrum sharing and coexistence: Requirements are given to facilitate effective sharing of the 6 GHz spectrum with existing and future radio systems. The standard addresses channel access mechanisms like Frame Based and Load Based Equipment, including Energy Detection Thresholds.
• User access restrictions: Restrictions and controls are specified to mitigate interference and ensure regulatory compliance for equipment installation, particularly for indoor and portable devices.

Applications

• Wireless Access Systems (WAS): The standard supports expanded deployment of 6 GHz wireless access infrastructure, enhancing high-speed connectivity in homes, enterprises, public spaces, and industrial settings.
• Radio Local Area Networks (RLAN): Enables Wi-Fi 6E and next-generation Wi-Fi devices to operate efficiently in newly opened 6 GHz bands, supporting high-throughput, low-latency applications such as video streaming, teleconferencing, and IoT device aggregation.
• Compliance for manufacturers: By adhering to SIST EN 303 687, manufacturers can ensure their 6 GHz radio products meet essential requirements of the Radio Equipment Directive (RED 2014/53/EU), facilitating CE marking and market access across Europe.
• Spectrum management: Regulators and service providers deploy compliant devices to manage spectrum efficiently, minimize harmful interference, and support seamless spectrum sharing among diverse users.

Related Standards

• ETSI EN 303 687 - The underlying European standard on which SIST EN 303 687 is based.
• ECC Decision (20)01 - Policy document on harmonised use of the 5 945 MHz to 6 425 MHz band.
• Commission Implementing Decision (EU) 2021/1067 - Defines rules for radio spectrum use across the 6 GHz band by WAS/RLANs in the EU.
• EN 301 893 - Related standard for 5 GHz WAS/RLANs, providing a framework for equipment operating in adjacent frequency bands.
• EN 300 328 - Standard for wideband data transmission equipment in the 2.4 GHz band, which complements the 6 GHz provisions.

SIST EN 303 687 V1.1.1:2023 is a fundamental reference for organizations designing, testing, and deploying 6 GHz wireless devices within the European regulatory landscape, helping ensure interoperability, safety, and efficient radio spectrum use.
