ETSI EN 300 220
ETSI EN 300 220 is a harmonized European standard that specifies technical requirements for Short Range Devices (SRD) operating in the 25 MHz to 1 GHz frequency range. It is applicable under the Radio Equipment Directive (RED) 2014/53/EU and covers various low-power wireless applications in the ISM and SRD bands.
Scope and Application
The standard applies to radio devices using analog or digital modulation techniques, including:
Narrowband and ultra-narrowband systems
Common technologies and applications:
Sub-GHz IoT systems (e.g. 868 MHz, 433 MHz, 915 MHz)
Smart metering and Wireless M-Bus
Remote keyless entry, alarms, industrial sensors
Proprietary FHSS systems and telemetry
Devices covered include:
Battery-powered radio transmitters and receivers
Sensors, actuators, control units, gateways
Data transmission systems up to 600 kbps
Frequency Bands
Typical operational sub-bands in Europe:
433.05–434.79 MHz (ISM)
863–870 MHz (SRD band)
868–870 MHz (IoT / LPWAN applications)
915 MHz (for global compatibility, not harmonized in EU)
The exact usable frequency and duty cycle depends on the band plan defined in ETSI TR 103 056 and national regulations.
Key Technical Requirements
Receiver category: defined performance classes (Category 1–3)
Modulation limits: compliance with spurious and out-of-band emission masks
Carrier power: typically ≤ 25 mW ERP, depending on band and use case
Occupied bandwidth: must fit within designated sub-band
Channel access: Listen Before Talk (LBT), Adaptive Frequency Agility (AFA), or duty cycle limits
Certification and Compliance
Devices must conform to EN 300 220 to demonstrate compliance with the Radio Equipment Directive (RED) and qualify for CE marking.
The certification process includes:
EMC and RF performance testing
Evaluation of spurious emissions and receiver blocking
Declaration of Conformity (DoC) with reference to EN 300 220
Note: EN 300 220 is often used in conjunction with EN 301 489-3 (EMC for SRD) and EN 303 131 or EN 303 204 for LPWAN systems.
