General Information
Overview
ETSI EN 303 204 V3.1.1 (2021-03) (identical to ETSI EN 303 204 V3.1.1) is a harmonised European standard that specifies technical characteristics and measurement methods for fixed Short Range Devices (SRD) used in data networks in the 870 MHz to 876 MHz frequency band. It covers radio equipment with power levels up to 500 mW e.r.p. and defines requirements for device classes that form fixed network topologies: Type 1a terminal nodes, Type 1b network nodes, and Type 1c network access points, all supporting adaptive power control.
Key topics and technical requirements
The standard addresses both transmitter and receiver performance, conformance testing and environmental profiles. Major technical topics include:
- Operating frequency range and channel spacing within 870–876 MHz
- Effective Radiated Power (e.r.p.) limits (up to 500 mW) and transient power behaviour
- Adaptive/automatic power control requirements and conformance criteria
- Frequency stability (including low-voltage conditions and frequency drift)
- Occupied bandwidth and transmission bandwidth specifications
- Unwanted emissions: out-of-band and spurious emissions limits and measurement methods
- Duty cycle and transmission timing (long- and short-term behaviour)
- Receiver performance: sensitivity, maximum input level, clear channel assessment (CCA) threshold, co‑channel rejection and adjacent-channel selectivity
- Measurement and conformance procedures and environmental test profiles
These topics are presented with specific limits, test descriptions and conformance criteria in the full text of the standard.
Practical applications
SIST EN 303 204 is intended for manufacturers, integrators and test laboratories designing and verifying fixed SRD radio equipment for data networks operating in the 870–876 MHz band. Typical practical uses include:
- Fixed wireless sensor and telemetry networks
- Network access points that bridge SRD networks to external services
- Industrial and enterprise data links where fixed SRD topologies are required
- Product compliance testing for CE marking and national spectrum access
Compliance with this harmonised standard helps demonstrate conformity with regulatory access conditions for the radio spectrum and facilitates market entry across European markets.
Who should use this standard
- Radio equipment manufacturers and RF design engineers
- Certification and conformity assessment bodies
- Test and calibration laboratories performing SRD testing
- Network architects and integrators deploying fixed SRD data networks
- National regulators and spectrum managers referencing harmonised access rules
