Specialists in Radio Testing internationally

Our Radio Testing services help you meet international wireless regulations, testing radio equipment products to support UKCA marking under the UK Radio Equipment Regulations, CE marking in Europe under RED, FCC (USA) and ISED (Canada).

Radio Testing

RN Electronics - the route to compliance for your radio products, including Wi-Fi, Radio and Telecoms equipment.

What is Radio Testing

Radio testing, or Radio Frequency testing, assesses radio equipment to ensure there is no interference with the devices and users of the nearby RF environment.

Why is Radio Testing Important

Radio testing is required to demonstrate compliance to most worldwide markets. Depending on the market / region, various compliance regimes are in place and are required to be followed to allow placing on that market compliant radio equipment. Radio equipment testing ensures that a device efficiently uses radio spectrum and also does not interfere with other radio spectrum users.

How We Can Help

RN Electronics has vast experience in ensuring legal compliance to meet local wireless regulations and our knowledgeable engineers are experts in radio/wireless product testing, including RF design troubleshooting, certifications/approvals and antenna testing.

Our product testing can help you meet key requirements to support the UKCA marking under the UK Radio Equipment Regulations, CE marking in Europe under the Radio Equipment Directive (RED) 2014/53/EU, FCC (USA) and ISED (Canada). Many other countries can be covered with the same standards, so please make contact for advice on specific countries.

Radio Technologies

Our testing covers many common radio technologies used in a wide range of products. These radio technologies include:

• Bluetooth – Classic (with EDR) and Low Energy
• Wi-Fi – 2.4 and 5 GHz WLAN
• ZigBee – DSSS (Direct Sequence Spread Spectrum) & LoRaWAN (Long-Range Wide-Area Network)
• Short Range Devices (SRD) – Including Z-Wave, RFID (Radio-Frequency Identification), Induction Loop, Land Mobile Service (Analogue and Digital), NFC (Near-field Communication)
• mmWave (Millimetre Wave) – Including wireless systems such as mmWave backhaul
• Satellite Positioning – GNSS (Global Navigation Satellite System)
• GPS and Cellular Technologies – Including GSM 2G/3G/LTE/4G in base stations and repeaters
• Private Mobile Radio (PMR) – This is also a requirement for marine radio and fixed link equipment

Radio Standards

Radio Equipment Directive (2014/53/EU) / Radio Equipment Regulations

The Radio Equipment Directive (2014/53/EU) has been in force since June 2016. From June 2017 onwards Radio Equipment placed on the European Market must comply with the Radio Equipment Directive (RED).

Compliance with the Radio Equipment Regulations for UKCA marking will be required, however in most cases it will be possible to use CE marking until 31 December 2021. From 1 January 2022 it will be necessary to use UKCA marking and Declarations of Conformity (DoC) to UK Radio Equipment Regulations.

Certification with the FCC / ISED

Electrical equipment marketed in the USA and Canada requires authorisation. There are two authorisation routes, SDoC and Certification. We can support these routes to compliance, including certification with the FCC and / or ISED.
