Narrowband hands-free communication in motor vehicles
|Publication Date:||1 March 2017|
The aim of this Recommendation is to define use cases and test methods for narrowband hands-free communication in vehicles. This Recommendation covers:
- built-in hands-free systems,
- after-market hands-free car kits,
- corded headsets, and
- wireless headsets,
to be used in vehicles for communication while driving.
This Recommendation addresses the test of complete systems, as well as the subsystems of hands-free microphones and telephones with short-range wireless transmission links used to interconnect the hands-free system to the mobile network. For testing, the test set-up and the recommended environmental conditions are described.
The methods, analysis and performance parameters described in this Recommendation are based on test signals and test procedures defined in [ITU-T P.501], [ITU-T P.502], [ITU-T P.340] and [ITU-T P.380].
Although important, subjective testing is outside the scope of this Recommendation; some guidance on how to conduct subjective tests can be found in clause 14.
