Overview

SIST EN 303 659 V1.1.1:2025 is a harmonised European standard that specifies the technical characteristics and measurement methods for Short Range Devices (SRD) in data networks operating in the frequency ranges of 865 MHz to 868 MHz and 915 MHz to 919.4 MHz. Developed by the Slovenian Institute for Standardization (SIST), this standard aligns with European requirements for access to the radio spectrum and compliance with Directive 2014/53/EU (the Radio Equipment Directive).

This document covers various types of SRDs, including Network Access Points (NAP), master NAP, NN, and TN devices intended for both indoor and outdoor environments. It sets out the fundamental requirements for spectrum access and the permitted effective radiated power (e.r.p.) for each device type.

Key Topics

• Frequency Ranges: Defines use and technical requirements for radio equipment in 865-868 MHz and 915-919.4 MHz bands.
• Device Types: Covers operational criteria for NAP, master NAP, NN, and TN SRD devices for indoor and outdoor use.
• Spectrum Access: Establishes harmonised conditions enabling efficient use of spectrum with minimal interference.
• Technical Requirements:
  • Environmental profiles and operating conditions
  • Effective radiated power limits
  • Unwanted emissions and spurious domain management
  • Bandwidth occupation and adjacent channel power limits
  • Transmitter and receiver conformance specifications
• Testing and Compliance:
  • Methods of measurement for transmitter and receiver characteristics
  • Specification of normal and extreme test conditions (temperature, humidity, power source)
  • Presentation and selection of equipment under test (EUT)
• Legal and Market Access: Provides a basis for demonstrating compliance with Article 3.2 of Directive 2014/53/EU, key for CE marking and EU/EEA market circulation.

Applications

SIST EN 303 659 V1.1.1:2025 applies to a broad range of short range wireless devices in data networks. Primary applications include:

• IoT networks: Smart meters, environmental sensors, asset tracking, and industrial automation devices utilizing low-power, short range communication.
• Building Automation: Wireless control and monitoring systems in smart homes and smart buildings.
• Inventory and Supply Chain: SRDs for asset management, RFID applications, and logistics operations.
• Consumer Electronics: Home automation and wireless security systems that require reliable, interference-free operation.
• Health and Medical Devices: Short range communication for patient monitoring and medical telemetry.
• Outdoor and Rural Networking: Devices that utilize the specified frequencies and comply with harmonised standards for outdoor deployment.

Following this standard helps manufacturers ensure interoperability, safety, and regulatory compliance, facilitating access to European and CEPT markets.

Related Standards

• ETSI EN 303 659: The European reference standard harmonised across member states.
• Directive 2014/53/EU (RED): Essential EU legislation for radio equipment conformance and CE marking.
• ERC/REC 70-03: Recommendations for short range devices and updated information on frequency band availability.
• ETSI EN 300 220: Standard for radio equipment used in the 25 MHz to 1000 MHz range.
• EFIS (European Frequency Information System): Provides up-to-date information on frequency band allocations across the EU and CEPT countries.

Note: National Radio Interfaces (NRI) may impose additional restrictions, particularly within the 915–919.4 MHz band. Manufacturers and integrators must consult local regulations for each target market.

---

By adhering to SIST EN 303 659 V1.1.1:2025, organizations ensure their short range wireless equipment can be marketed and deployed efficiently across Europe, supporting robust and compliant data network solutions in critical frequency bands.
