Eight Japanese companies have joined forces to establish communication protocols for use in transmitting data to mobile users. The group, which is called the MobileWeb Consortium, includes Sharp Corp, IBM Japan Ltd, Pioneer Electronics Corp, Honda Motor Co, and Mazda Motor Corp. According to Asian news sources, the group has already decided to adopt MobileWeb 1.0 as a standard for use in car navigation systems and they will now be studying protocols for a number of portable terminals such as personal digital assistants (PDAs) and other wireless data devices. Work on deciding specifications for car navigation systems began in January and the original agreement to form a consortium was made between just five companies that included IBM Japan and Sony.
