The following section describes the system architecture of Inter-Processor Communication on

a WWAN M.2 module when connected to a Microsoft Windows® based Host OS Windows®

7, Windows® 8.x.

The software components of a WWAN M.2 module running Windows® 7 and

Windows® 8 are depicted in Figure 12 and Figure 13 respectively.

In the Windows® 7 architecture:

The Windows® 7 driver interfaces with the WWAN M.2 modem using a virtual

terminal connection over CDC-ECM.

A Third party connection manager utilized

Independent Hardware Vendor (IHV) provided MBIM driver

In the Windows® 8 architecture:

Microsoft requirements:

o MBIM interfaces

o User Mode Driver Framework (UMDF) driver for GNSS, and Firmware

Update, Carrier Switching application.

o RTD3 support

For all Windows platforms:

The WWAN M.2 module is exposed as a composite device

GNSS will be supported through a serial interface

When mobile broadband is disabled, GNSS will still be available.

The mobile network adapter driver will interface to the modem software through the

MBIM interface.

All Intel specific features will be supported through MBIM.

The connection manager provided with Win 8 OS and above will be used. For

Win 7, the IHV provided connection manager is used.

There will be an application layer to hide the differences in the mobile broadband API

between Win 7 and Win 8.
