WLAN Testing

Regulatory tests for products with WiFi technology

Many technical products are equipped with interfaces for wireless LAN (WLAN). The use of this wireless technology results in various test scenarios, which are necessary for the certification of a device and thus for its market launch.

Regulatory requirements for WLAN Testing

Worldwide communicated frequency bands in the range of 2.4 GHz or 5 GHz are available as basebands for the use of a WLAN device. When using a WLAN module, the manufacturer therefore has to decide in which frequency bands the module should transmit: 2.4 and/or 5 GHz.

The selection of the frequency bands has an impact on the regulatory test scope required for certification in the target market. Many countries and certification regimes establish their own standards, limits and specifications that must be used for the test process for equipment using radio technologies. This also applies to WLAN technology. A glance at three of the largest markets gives an idea of how many different regulatory requirements have to be dealt with simultaneously:


Frequency band EU (CE) North America (FCC/ISED) Japan (ARIB)
2,4 GHz EN 300 328 FCC Part 15.247 Ordinary Regulatory Radio Equipment Art. 2 item 19
5 GHz EN 300 328 FCC Part 15.247


The test standards serve as a basis for the WLAN testing and are to be regarded as the basis for a successful market approval for the markets mentioned. Depending on the number and type of other target countries for your product, there are additional test specifications that your product must pass. We would be pleased to help you identify these and carry out all necessary tests in our accredited laboratories at your request.

Wi-Fi Alliance® certification

In addition to the regulatory tests and the certification based on them, there is also the option of certifying the product according to the specifications of the Wi-Fi Alliance® when using WLAN modules. The Wi-Fi Alliance® is a worldwide network of companies that is concerned with the quality and further development of Wi-Fi® technology and, in this context, also publishes certification guidelines according to which manufacturers can certify their devices.

In this certification, which has no regulatory character but is regarded worldwide as a seal of quality, the devices undergo various tests. Not only the WLAN functionality is tested, but also, at the same time, on the basis of the standards recognized by the industry (IEEE 802.11), that interoperability, security and a number of application-specific protocols are fulfilled.

You can rely on our reliable testing of WLAN-compatible devices. Benefit from robust results that will help you move your products forward on the road to market approval. Stay informed at all times. With us you know the status of our project and know which steps are still to come – at all times.

Our services

In our test laboratories in Germany and the USA, we carry out regulatory tests for all WLAN products, which form the basis for the international market approval of products with WiFi technology.

Our service portfolio is not limited to the above-mentioned requirements from the USA, Japan and the EU. Our test services in our ISO 17025 accredited laboratories include regulatory WLAN testing for a variety of international certification regimes based on different test specifications and standards.

Our laboratory in Milpitas (Silicon Valley) is also accredited by the Wi-Fi Alliance® as an authorized test laboratory for Wi-Fi Alliance® certification. In this capacity, as a testing and certification service provider, we can perform tests for specific Wi-Fi Alliance® programs in addition to regulatory testing for WLAN products. These include Wi-Fi 6 Certified and Wi-Fi CERTIFIED Agile Multiband.
