Non-profit organisation that promote and support the Universal Serial Bus, USB-IF has released of the Mobile Broadband Interface Model (MBIM) 1.0 Specification.

MBIM 1.0 is a USB-based protocol for host and device connectivity for desktops, laptops, tablets and mobile devices which supports multiple generations of GSM and CDMA-based 3G and 4G packet data services including the LTE technology.

MBIM 1.0 supports multiple IP connections per a single USB interface, enables flexible, efficient and lower cost device implementations, supports power-friendly implementations in diverse operating systems and enables implementation of device-agnostic mobile broadband class drivers in diverse operating systems for desktops, laptops, tablets and mobile devices.

In addition, the new protocol replaces cumbersome control channel mechanisms, such as AT-commands and minimises overhead and improves data transfer efficiency by sending raw IP frames, eliminating the need for Ethernet headers.

USB-IF president & COO Jeff Ravencraft said the USB-IF is excited to add the MBIM specification to its set of specifications.

"USB technology benefits the mobile device consumer, and the MBIM specification expands the capabilities that USB delivers to mobile device platforms," said Ravencraft.
