2. ITU test event: HEAD acoustics again selected as test laboratory
After the first ITU test event in May 2014, now the second event will be taking place: from May 23 to 27, 2016, mobile phones will be tested again in Geneva regarding their speech quality in conjunction with vehicle-mounted hands-free telephone systems. Especially for car manufacturers, hands-free terminals system suppliers, mobile network operators and mobile phone vendors this is an interesting event. As two years ago, HEAD acoustics is again selected as the official test laboratory providing the necessary test equipment: the measurement front end MFE XI (Universal Bluetooth® Access Point) as well as the communication quality analysis system ACQUA with the measurement standards P.1100, P.1110 and HQS-Bluetooth®-Source.
In this day and age, hands-free communication is an integral part of the vehicle. For an optimal communication the hands-free algorithms and the mobile phone are responsible equally. Nevertheless, not least the test conducting in 2014 have shown that often the mobile phone does not deactivated the internal signal processing - as requested in current standards - and thus caused poor car hands-free performance. Also at the second test event, the measurements will be conducted in accordance with Chapter 12 of the ITU-T Recommendations P.1100 ("Narrowband hands-free communication in motor vehicles") and P.1110 ("Wideband hands-free communication in motor vehicles"). Mobile phones which work properly with a vehicle’s hands-free telephone system will be published in the official ITU whitelist afterwards.
„The results of the first test event have attracted great media attention. This emphasizes the importance of these tests for the supplier and automotive industry and their customers,“ said Frank Kettler, Consulting Manager Telecom, who accompanies the measurements on-site. „Therefore, it is a great pleasure, to be selected as test laboratory again and to conduct the numerous measurements with our equipment.“
Further information can be found on the    official ITU website for the test event.
