Standards & ProtocolsEuropean standard defining UHF RFID radio parameters at 865-868 MHz with Listen Before Talk channel access for the EU market.
ETSI EN 302 208
etsi-302-208-term/" class="glossary-term-link" data-term="ETSI EN 302 208" data-definition="European UHF RFID radio standard." data-category="Standards & Protocols">ETSI EN 302 208 is the European Telecommunications Standards Institute harmonised standard that defines the radio parameters for UHF RFID equipment operating in the 865-868 MHz band within the European Union and associated countries. It is the European counterpart to FCC Part 15 in the United States.
Key Parameters
| Parameter | ETSI EN 302 208 | FCC Part 15 (US) |
|---|---|---|
| Frequency band | 865.0 - 867.6 MHz | 902 - 928 MHz |
| Number of channels | 4 (200 kHz each) + 6 (200 kHz) | 50+ (500 kHz each) |
| Max ERP | 2 W (33 dBm) | 4 W (36 dBm) |
| Channel access | Listen Before Talk (LBT) | FHSS |
| Bandwidth | 1.6 MHz (865-867.6) | 26 MHz (902-928) |
| Dwell time | No fixed limit (LBT-based) | 400 ms per channel |
Listen Before Talk
The defining characteristic of ETSI EN 302 208 is the Listen Before Talk channel access method. Before transmitting, a reader must sense the channel for a minimum period. If the channel is clear (below -83 dBm), the reader may transmit for up to 4 seconds. If the channel is occupied, the reader must wait and retry.
LBT prevents reader-to-reader interference in dense reader mode environments but reduces throughput compared to FCC FHSS, where readers hop rapidly across 50+ channels without listening.
Impact on System Design
The narrower European bandwidth (1.6 MHz vs. 26 MHz in the US) and fewer channels affect system design in several ways:
- Reduced throughput -- fewer available channels limit aggregate read rate in dense deployments.
- Reader coordination -- dense reader mode is more important in ETSI regions.
- Dual-band readers -- global deployments require readers that support both 865-868 MHz (ETSI) and 902-928 MHz (FCC) bands.
- EIRP budget -- the 2 W ERP limit modestly reduces read range compared to US deployments.
Regulatory Context
ETSI EN 302 208 is a harmonised standard under the EU Radio Equipment Directive (RED 2014/53/EU). Compliance with this standard provides a presumption of conformity with RED essential requirements. All RFID readers sold in the EU must carry CE marking and meet ETSI EN 302 208.
