UNH-IOL Launches Automotive Audio Bus Testing Services for In-Vehicle Audio Devices

The University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent provider of broad-based testing and standards conformance services for the networking industry, has announced its key role in the advancement of the Automotive Audio Bus (A2B®) technology developed by Analog Devices, Inc, the company said.

The UNH-IOL will serve as the industry´s first laboratory for A2B conformance testing, which is an essential element of the broader A2B ecosystem.

A2B is a low-latency digital audio bus that transmits audio and control data together with clock and power over a single unshielded twisted pair cable. Its daisy-chain capability reduces cable weight and system complexity while improving fuel efficiency – making it particularly well suited for emerging wiring-intensive applications such as Road Noise Cancellation, Personal Audio Zones, and In-Car Communications. A2B´s architectural simplicity, zero processor overhead, and easy to use graphical development environment combine to enable industry-leading time to market.

Working closely with Analog Devices, the UNH-IOL assisted in the development of the test service to validate A2B solutions coming from the company´s customers. By pre-testing devices to the A2B specification at the UNH-IOL, system manufacturers can ensure their products interoperate seamlessly with other A2B products used in an application. While the A2B technology was initially targeted towards automotive use cases, there is also a future for A2B in emerging consumer and building technology segments.

The UNH-IOL is dedicated to being the world´s premier data networking resource. Beginning in 1988, the UNH-IOL has built a multimillion dollar testbed and developed testing solutions to help companies efficiently and cost effectively deliver products to market. UNH-IOL´s services fit the needs of the market, while maintaining broad, comprehensive interoperability and conformance testing of networking, data, telecommunications, and storage products.
