Daimler Introduces MOST150 in the New Mercedes-Benz S-Class

Press release date: February 13, 2014

Karlsruhe (Germany)— The MOST(r) Cooperation - standardization organization for the leading automotive multimedia network technology Media Oriented Systems Transport (MOST) - is delighted to announce that Daimler implemented MOST150 in its new Mercedes-Benz S-Class vehicles. "MOST150 has successfully accomplished series development for the next Mercedes-Benz infotainment generation, with fully-qualified series production parts available for all key components," stated Peter Haeussermann, Head of Telematics Electrics/Electronics at Daimler AG. "MOST150 has recently been first implemented in the brand-new generation of the S-Class. After that, the technology will be rolled out onto all other Mercedes-Benz car lines, step by step."

Smooth Migration to New Functions

The development of this newest MOST generation has been accompanied by a cost/benefit analysis that led to several innovations on one hand and to a high level of backward compatibility on the other. Existing applications can easily be reused in the new network by simply modifying their network interfaces. Therefore, it offers a smooth adaption with the majority of features being continued. Daimler will reuse and adopt many components out of their proven system architectures, as for example, main parts of topologies, network management and application structures. As a result, the focus will be on the development of new functions.

Automotive IP Network and Internet Application

Peter Haeussermann added, "At Daimler, we expect that the prevalence of internet applications in the automotive environment will grow significantly. Consequently, future infotainment platforms have to meet these new requirements." MOST150 makes a crucial contribution to this by providing the MOST Ethernet protocol. With this new communication channel, both high-performance IP networks and internet applications can easily be implemented. The Ethernet channel can transmit unmodified Ethernet frames (according to IEEE 802.3) with more than 100 Mbit/s depending on the network configuration. This permits software stacks and applications from the consumer and IT domain to be seamlessly migrated into the car. TCP/IP stacks or protocol entities utilizing TCP/IP can communicate via MOST without any modification. Thus, the new generation of MOST provides the automotive-ready physical layer for Ethernet in the car.

About MOST Technology
MOST (Media Oriented Systems Transport) is a multimedia networking technology optimized for use in cars and other applications. It enables the transport of high Quality of Service audio and video together with packet data and real-time control over a single transmission medium. MOST can use plastic optical fibers (POF), coax based electrical physical layer, and shielded and unshielded twisted pair (STP/UTP) copper wires that meet automotive environmental requirements. Today, MOST is used in over 150 car models as the communication backbone for their information and entertainment equipment.

About MOST Cooperation
The MOST Cooperation (MOSTCO) is the organization through which MOST Technology is standardized and refined so that it continues to stay abreast of the latest industry requirements. Today it consists of 16 international carmakers and more than 60 key component suppliers. They have joined together to work with the MOST Technology and to contribute to its innovation. The MOST Cooperation is prepared to embrace efforts to further develop and standardize the technology for other industries and to establish the corresponding work structures. The MOST Cooperation was founded in 1998 to standardize MOST Technology as a global standard for multimedia networking. Audi, BMW, Daimler, HARMAN and Microchip Technology are its core partners and constitute its Steering Committee. For more information see
