Bluetooth® testing
Communication and audio devices
From mobile phones and vehicle hands-free systems to speakers, conventional headphones and headsets, Bluetooth® wireless technology can be found in nearly all communication and audio devices – albeit profiles, codecs, signal processing methods and more may differ.
But the aim is always the same: to give end customers the best-possible user experience thanks to high-quality audio playback and lossless communication between devices. Manufacturers have to ensure this by conducting a range of acoustic and electrical tests.
Optimizing Bluetooth® voice quality
Realistically and reproducibly testing voice and audio quality via a Bluetooth® connection poses a real challenge for manufacturers. The wireless connection of devices via Bluetooth® can have a significant impact on both, communication and audio quality.
Manufacturers require special measurement procedures and a reference interface for ensuring key criteria:
- Correct implementation of profiles, codecs and protocols for sink, source and gateway applications
- Verification of levels, latency and transmission behavior
- Optimization of signal processing depending on the application
Reproducible measurement and simulation procedures
The combination of a reference interface with test procedures for a range of Bluetooth® compatible audio and communication devices provides manufacturers and test laboratories with a unique test environment.
Our solutions enable lab-based testers to:
- Establish a direction connection with the reference interface
- Ensure compatibility and conformity among devices for all standard profiles and codecs (e.g. HFP, A2DP, Qualcomm® aptX™, mSBC)
- Optimize signal processing (audio quality, level, echo compensation, noise suppression, etc.) where required
- Ensure transparent and error-free transmission for gateway applications
- Check the correct implementation of different connection types and associated protocols (e.g. AT commands such as “NREC Off”)
- Test complex scenarios
