Radio frequency testing to ensure compliance of your wireless equipment with international regulatory requirements
In order for radio and telecommunications equipment to be sold in various markets worldwide, it is a legal requirement to ensure that these wireless devices are compliant with radio frequency test standards for short range devices, including Bluetooth, Wi-Fi (802.11a/b/g/n/ac) and Zigbee, PMR radio, RFID, NFC, GPS and cellular technologies like GSM, CDMA, 2G/3G/LTE in base stations, repeaters, mobile stations and user equipment. These complex requirements vary from region to region. What’s more, they not only apply to manufacturers but also to the persons responsible for placing the devices on the market. Understanding the regulations for radio frequency testing of your intended markets takes considerable time and effort.
What is radio frequency testing?
Radio frequency (RF) testing simulates the functionality and performance of radio and telecommunications equipment to ensure each device will not interfere with other users of the radio frequency spectrum. Thereby, radio frequency tests verify that the radio equipment is using the radio spectrum effectively and thereby support the efficient use of radio spectrum. Other tests are also usually required to verify that your device meets local regulations for electromagnetic compatibility (EMC), electrical safety and RF exposure.
Therefore, radio frequency testing refers to the evaluation of radio equipment, i.e. any electrical or electronic product, which intentionally emits and/or receives radio waves for the purpose of radio communication and/or radio determination. Thereby, radio waves are electromagnetic waves lower than 3000 GHz propagated in space without artificial guide.
Radio frequency testing includes transmitter and receiver test cases on radio equipment. A transmitter shall only create radio wave emissions that do not create harmful interference.
A receiver shall have a performance level that allows to operate as intended and protects it against the risk of harmful interference, in particular from shared or adjacent channels. Thereby, it shall support the efficient use of shared or adjacent channels. The receiver resilience against unwanted signals also supports the efficient use of radio spectrum.
Why is radio frequency testing important?
Radio frequency compliance is a mandatory requirement in most international markets including the EU, USA, Canada, Australia and Japan. If you manufacture wireless devices or incorporate wireless devices into your end product, you must comply with the regulations of your intended markets, otherwise your products cannot be legally sold.
With TÜV SÜD as an experienced testing and certification body for radio frequency testing you can avoid compliance failure and unnecessary market recalls or costly rework and gain global markets access easily. At the same time your product performance can be improved radio frequency tests and conformity assessments by a third party like TÜV SÜD also helps you to strengthen your competitive position in the market.
How can we help you?
TÜV SÜD supports you to achieve compliance with international radio frequency standards. We assist you already during your product development phase so that necessary radio frequency requirements are already considered from the beginning on. This enables early identification of any design flaws and improves the prospects of success during formal testing. Thereby, we can ensure that your radio equipment fulfils the physical layer characteristics specified for transmitting and receiving functions.
TÜV SÜD has many years of experience in the testing and certification of various wireless devices for global markets. We also test marine equipment implementing DSC, ATIS, AIS, EPIRB, VHF/HF radios, DVB & DAB.
Our engineers are happy to support you from pre-compliance investigation and de-bugging sessions to full compliance and conformance testing within our radio frequency laboratories. We also assist our customers as Notified Body in case non-harmonised standards are used for your testing in the EU.
To cover all of your radio frequency testing requirements, we are able to provide a one-stop-shop solution for all types of testing like safety, EMC (electromagnetical compatibility) and environmental testing through our global network of accredited testing laboratories and a world-leading certification service.
All your devices can be tested in our global network of accredited radio frequency testing laboratories. Our experts are always up-to-date with regard to regulatory changes and are able to efficiently support you in meeting the relevant test and certification requirements.
