Bluetooth Product Testing

Bluetooth® technology connects our world - without any wires at all. Among other things, it enables computers, laptops, smartphones and even medical devices to communicate over short ranges using UHF radio waves in the globally available ISM band at 2.4 GHz. However, in order for the respective devices to function without restriction with this technology, they must undergo a series of tests before they are certified and thus approved for the market. Whether tests of radio frequencies, electromagnetic compatibility (EMC) or even electrical safety tests - we carry out all the necessary tests under one roof and are also available to you as a testing partner for certification in accordance with the specifications of the Bluetooth SIG (Special Interest Group).

Regulatory Standards

A market launch of an end product with radio technology is only possible if it complies with the regulations valid in the respective target country. These are specified by the local authorities.


DIN EN 300 328


FCC § 15.247

Bluetooth Low Energy (BLE)

Bluetooth Low Energy is an innovative wireless standard that allows a Bluetooth connection to be established with low transmission power and low power consumption. This technology has many applications in fitness trackers, sensors and toys. The big advantage is that a connection can be established without wasting unnecessary energy. Only a minimum transmission power of about 10 mW is required.

However, Bluetooth Low Energy also has some disadvantages. It is generally slower than classic Bluetooth and its range is limited to about 10-40 meters because it has a reduced transmission power. In addition, Bluetooth LE has limited backward compatibility, which means that a connection can only be established if the remote device also supports Bluetooth Low Energy. Fortunately, most devices from Bluetooth 4.0 onward support this technology, which increases compatibility.

Smartphones and Computers usually have both Bluetooth interfaces: a normal Bluetooth interface (BR/EDR controller) and Bluetooth Low Energy support (LE controller). Pure BLE devices only have support for the low-power variant.

What is the role of Bluetooth SIG?

The Bluetooth SIG is responsible for product certification and the resulting market approval. As part of the Bluetooth qualification process, a product that incorporates a Bluetooth design must pass the conformance requirements prescribed by the Bluetooth SIG. When submitting your products for qualification, the Bluetooth Qualification Consultant (BQC) will assist you. Qualification of your Bluetooth-enabled product is essential for a successful market launch.

Frequently Asked Questions

All you need to know about Bluetooth Product Testing

What is regulatory testing of Bluetooth devices for?

Regulatory testing of Bluetooth devices is necessary to ensure the safety and performance of Bluetooth products used by end users. It ensures that Bluetooth devices meet certain regulatory requirements and standards set by government agencies around the world.

Is Bluetooth licensed?

Yes, Bluetooth is licensed. A license must be purchased for each device with Bluetooth technology, which is available through the Bluetooth SIG qualification process.

Are there situations where I don't need to qualify my product?

If you only want to distribute a company's Bluetooth product and not label it as your own, qualification is not required.

What is the difference between regulatory testing and Bluetooth SIG testing?

Regulatory tests are mandatory tests designed to ensure that Bluetooth devices comply with regulatory standards and regulations for worldwide market access. These tests cover aspects such as electromagnetic compatibility, safety and conformity. Tests according to Bluetooth SIG specifications, on the other hand, are not mandatory but optional. They are specific tests that ensure that a Bluetooth device complies with Bluetooth SIG specifications and standards. The Bluetooth SIG provides these tests to member companies to ensure the compatibility of Bluetooth devices. The tests cover aspects such as functionality, performance and interoperability with other Bluetooth devices.
