Hands-free Communication

Experience seamless communication

Whether conference systems, door intercom systems or a mobile phone in hands-free mode – whatever the device or environment, customers expect the same seamless communication quality as when using their mobile phone or attending live conferences. From a technical perspective, this represents a challenge for manufacturers. They have to not only conduct device-specific testing, but also optimize the system for users and interlocutors on the other side alike.

Meeting every challenge with hands-free communication

A whole range of aspects needs to be taken into account when measuring and optimizing hands-free scenarios. In addition to fine-tuning the relevant communication parameters, the following factors also play a role:

Speakers, microphones and their positioning
Voice quality in sending and receiving direction
Intelligent echo and background noise suppression
Enabling of uninterrupted double talk and background noise transmission
Realistic simulation of user behavior and ambient noise in the lab

A comprehensive analysis of hands-free technologies

Users expect hands-free communication free of interruptions and artifacts – and this is exactly what manufacturers and test laboratories are expected to deliver. Using our unique combination of measurement, analysis and simulation solutions, devices can undergo comprehensive testing and optimization in form of:

Automated tests in accordance with international standards (e.g. 3GPP TS 26.131/132, ETSI TS 103 737-740)
Manufacturer- and provider-specific tests
Tests of all relevant communication parameters in sending and receiving direction as well as during double talk
Complex test scenarios involving multiple talkers and varying talker positions
Realistic simulation of background noise and reverberation

Thanks to our decades of experience with hands-free technologies, we offer everything you need to conduct device-specific testing that goes above and beyond international specifications.
