A proposed standard from the International Telecommunication Union (ITU) for a fourth-generation mobile wireless communication system. The Mobile Broadband System (MBS) is a project of the Research and Technology Development in Advanced Communications Technologies in Europe (RACE) program.
It extends mobile telecommunications to include broadband communication and offers multimegabit data transmission rates of up to 155 Mbps for wireless transmission of multimedia video and audio content. The technology underlying MBS is Asynchronous Transfer Mode (ATM) networking; the standard will fully integrate MBS with the ATM-based Integrated Broadband Communications Network (IBCN) proposed for Europe.
MBS is a wireless extension to broadband ISDN (B-ISDN) communication, which is still in the developmental stage.
