Overview
SIST EN 304 220-1 V1.2.1:2024 (identical to ETSI EN 304 220-1 V1.2.1:2024-08) is a harmonised European standard for wideband data transmission Short Range Devices (SRD). It defines the technical characteristics and test methods for network access point (NAP) equipment operating in the frequency ranges 863 MHz–868 MHz and 915.8 MHz–919.4 MHz. The standard supports conformity assessment and regulatory compliance for devices that use wideband modulation techniques to access the radio spectrum. It also maps to the essential requirements of Article 3.2 of Directive 2014/53/EU (see Annex A).
Key topics and technical requirements
The standard sets out requirements and measurement methods across transmitter, receiver and spectrum access areas, including:
Device categories and frequency allocation
- Type 1: NAP in 863.0–868.0 MHz
- Type 2: Master NAP in 915.8–919.4 MHz (and 917.4–919.4 MHz)
- Type 3: NAP in 915.8–919.4 MHz (and 917.4–919.4 MHz)
- National availability may vary; consult EFIS/CEPT and CEPT/REC 70-03 appendices.
Transmitter requirements
- Frequency error, effective radiated power (ERP), occupied bandwidth
- Transmitter spectrum emission mask and unwanted (spurious) emissions
- Duty cycle and transient power behaviour
Receiver requirements
- Receiver sensitivity, adjacent-channel selectivity, spurious response rejection
- Blocking performance, receiver spurious emissions, maximum input signal level
Spectrum access and coexistence
- Clear channel assessment (CCA) thresholds
- Listen Before Talk (LBT) procedures and related conformance testing
Conformance and test methods
- Environmental profile, general performance criteria and standardized measurement procedures for laboratory and certification testing
Practical applications and users
This harmonised standard is primarily intended for:
- Device manufacturers developing wideband SRD network access points and master NAPs
- Test laboratories and certification bodies performing conformity assessment to CE marking and EU RF regulations
- Network integrators and system designers specifying access-point hardware for private or commercial data networks
- Regulators and technical policy teams harmonising spectrum access and enforcing technical limits
Typical use cases include wireless data networks and networked short‑range communications where wideband modulation is required for higher data throughput and robust coexistence.

The standard SIST EN 304 220-1 V1.2.1:2024 serves a critical role in the field of wideband data transmission Short Range Device (SRD) network access points, focusing specifically on devices operating within the frequency bands of 863 MHz to 868 MHz and 915.8 MHz to 919.4 MHz. This standard lays down comprehensive technical characteristics and test methods crucial for the conformance assessment of wideband data transmission network access point equipment. One of the significant strengths of this standard is its clear delineation of the types of equipment covered. It categorizes devices as Type 1, Type 2, and Type 3 based on their operating frequency ranges, thereby providing clarity for manufacturers and stakeholders in the industry. This structured approach not only facilitates compliance but also enhances interoperability among devices operating in these designated frequency bands. Furthermore, the standard addresses the varying availability of the frequency bands across different countries, ensuring that manufacturers involved in the wideband data transmission sector are adequately informed about national regulations and potential restrictions. This is particularly crucial as it allows companies to tailor their products according to regional specifications and operational requirements. The technical measurements and testing methods outlined in this document promote reliability and quality assurance for wideband data transmission devices. By establishing a standard set of criteria, the standard supports the development of robust equipment that adheres to essential regulatory requirements, such as those specified in Article 3.2 of Directive 2014/53/EU. Overall, the relevance of SIST EN 304 220-1 V1.2.1:2024 in today's technological landscape cannot be overstated.
