MOST® Worldwide
MOST Cooperation Announced the Worldwide Acceptance of Over 200 Vehicle Models with MOST Inside During the 8th MOST Forum
(PresseBox) (Karlsruhe, )Three MOST Generations
The first generation, MOST25, operates at 25 Mbit/s. It made it into production only three years after the MOST Cooperation was founded: in 2001, the first MOST car was introduced. MOST25 is based on optical data transmission using optical fibers.
With MOST50, the MOST Cooperation doubled the bandwidth for automotive infotainment solutions from 25 to 50 Mbit/s. The "MOST Specification of Electrical Physical Layer Rev. 1.1" is an additional key specification that enables data transmission over a shielded or even an unshielded twisted pair (UTP) cables while meeting the stringent automotive electromagnetic compatibility requirements.
MOST150 is the third generation, offering a bandwidth of 150 Mbit/s. With transmission over legacy POF/LED optical physical layer, MOST150 offers a smooth migration from MOST25 and MOST50. In addition to higher bandwidth, MOST150 features an isochronous transport mechanism to support extensive video applications as well as an Ethernet channel for the efficient transport of IP-based packet data. Additionally, the "MOST150 Coax Physical Layer Sub-Specification Rev. 1.1" defines a physical layer that is able to provide bi-directional communication and to supply power over a single coaxial cable.
MOST offers a network architecture for HD audio/video and IP-based applications: MOST provides a powerful, flexible, and up-gradable network architecture that forms a stable, robust backbone to easily and seamlessly integrate many applications. The MOST network concept is inherently scalable and extendable with respect to speed and types of data channels. MOST connects to other industry standards such as Universal Plug and Play (UPnP) communication based on the Internet Protocol (IP) and AUTOSAR.
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, over 200 car models use MOST as the communication backbone for their information and entertainment equipment.
