Congress 2013 
New Middleware Makes USB MBIM Standard Available for Multiple
Operating Systems, Hardware Platforms and Chipsets 
ALISO VIEJO, CA -- (Marketwire) -- 02/25/13 --  Smith Micro Software,
Inc. (NASDAQ: SMSI) announced today the availability of its new
QuickLink(R) MBIM Middleware for chipset vendors and device
manufacturers. The Mobile Broadband Interface Model (MBIM) standard
for broadband connectivity, developed by the USB Implementers Forum
with contributions from Smith Micro, was first commercialized on
broadband devices supporting Windows 8. QuickLink MBIM Middleware
extends MBIM functionality to Windows 7 and other operating systems.
This provides backward compatibility between new USB and embedded
modems with prior versions of Windows and reduces support burden from
legacy operating systems in the market. 
"The new MBIM standard is a step forward for mobile broadband
connectivity, but many device makers and operators are concerned
about new broadband devices supporting operating systems other than
Windows 8," said Dave Sperling, CTO of Smith Micro Software. "Having
dealt with multi-platform support for decades, we saw the opportunity
to extend the MBIM inter
face to more platforms in a way that would
benefit many players in the ecosystem. For example, the use of
QuickLink by mobile chip vendors will help OEMs and wireless
operators launch mobile broadband devices faster and deliver a true
plug-and-play experience to subscribers." 
Smith Micro's QuickLink MBIM Middleware brings the following benefits
to the market: 

--  Eliminates the need by OEMs to develop costly operating system and
    device-specific drivers
--  Simplifies development of advanced M2M solutions and services by
    standardizing the broadband modem interface
--  Streamlines the certification of new mobile broadband devices in
    operator test labs
--  Reduces support costs by eliminating driver conflicts on legacy
--  Improves the "out of box" user experience by enabling plug-and-play
    for USB modems
