Mobile Broadband Changes for Windows 7
Updated: December 10, 2009
Windows 7 defines a new driver model for mobile broadband devices. The model defines a new interface for mobile broadband devices to integrate with Windows and uses new features introduced by Network Driver Interface Specification (NDIS) 6.20. Network applications that were written for NDIS 6.0 or earlier and perform packet capture, filtering, or injection at the media access control (MAC) layer—such as firewalls, antivirus filters, and virtual private network (VPN) clients— might require updates to work with mobile broadband devices.
This paper discusses important changes in the mobile broadband stack for Windows 7, provides guidance for testing applications for compatibility with mobile broadband, and describes the changes that are required to update the applications to work with mobile broadband devices on Windows 7. This information is intended for application developers who create or maintain network applications such as firewalls, antivirus filters, and VPN clients.
This information applies to the Windows 7 operating system.
