Compatible Electronics

Short range device SRD testing to ETSI EN 300 220 and EN 300 440

Short Range Device (SRD) Testing Services

Compatible Electronics provides testing services for short range devices (SRDs) operating in sub-GHz and higher unlicensed bands. We test to ETSI standards for European compliance and equivalent international standards, with NVLAP accreditation for EN 300 220 and EN 300 440 — the two primary ETSI SRD standards.

What are Short Range Devices?

Short range devices are radio equipment designed to provide wireless communication over limited distances with low power output. SRDs include remote controls, wireless sensors, alarms, telemetry systems, keyless entry systems, and IoT devices operating in designated licence-exempt frequency bands. ETSI EN 300 220 covers sub-1 GHz SRDs (25 MHz to 1000 MHz) while EN 300 440 covers SRDs from 1 GHz to 40 GHz.

SRD Frequency Bands & Testing Requirements

Frequency Bands

  • 868–870 MHz — Europe (primary SRD band; duty cycle limits per sub-band)
  • 902–928 MHz — Americas (FCC Part 15 unlicensed band)
  • 433.05–434.79 MHz — Europe and international ISM allocation
  • 315 MHz — United States only (not an EU SRD allocation)
  • 2400–2483.5 MHz — global ISM; WiFi, Bluetooth, Zigbee
  • 5725–5875 MHz — global ISM
  • Region-specific allocations — AS/NZS 4268 for Australia/New Zealand

Testing Requirements

  • Transmitter power — ERP and EIRP at maximum power
  • Frequency accuracy and stability
  • Occupied bandwidth
  • Spurious emissions in transmit mode
  • Spurious emissions in receive/standby mode
  • Duty cycle compliance per EN 300 220 sub-band limits
  • Listen Before Talk (LBT) verification where required
  • Adaptive Frequency Agility (AFA) where applicable

Real-World Testing Examples

Remote Keyless Entry — EN 300 220 + FCC

An automotive supplier required CE marking and FCC compliance for a 433 MHz remote keyless entry transmitter included with a vehicle accessory product. Compatible Electronics performed ETSI EN 300 220-2 testing for the CE marking RED Declaration of Conformity, covering EIRP, frequency accuracy, occupied bandwidth, and spurious emissions. Parallel FCC Part 15C testing per ANSI C63.10 was performed for the US market. The combined test report package covered both markets from a single test session.

Industrial Wireless Sensor — 868 MHz EU SRD

A process automation manufacturer needed CE marking under RED for a battery-powered temperature and humidity sensor transmitting on 868 MHz. Testing to EN 300 220-2 confirmed compliance with the 868.0–868.6 MHz sub-band ERP limit (25 mW), duty cycle limit (1%), and spurious emission requirements. The sub-band duty cycle constraint required careful firmware configuration testing across multiple transmission intervals to confirm worst-case duty cycle compliance.

Wireless Tire Pressure Monitor — 315 MHz + 433 MHz

A TPMS manufacturer needed FCC certification for 315 MHz US-market sensors and CE marking for 433 MHz EU-market sensors within the same product family. Compatible Electronics performed ANSI C63.10 Part 15C testing for the 315 MHz US variant and EN 300 220-2 testing for the 433 MHz EU variant, producing separate FCC and RED test packages for the two product variants from a coordinated test program.
