Using the Mobile Broadband Platform in Windows 7

2. Using the Mobile Broadband Platformin Windows 7 Kurt Hunter Senior Program Manager Microsoft Corporation

3. Objectives • Review the collective set of mobile broadband (MB) features in Windows® 7 • Inspire you to build your mobile broadband solutions using these features

4. Agenda • Overview of new mobile broadband features in Windows 7 • Description of each mobile broadband component • User experience and Connection Manager • Driver model • Mobile broadband application programming interface (API) • Logo program for mobile broadband • Device Stage™ for mobile broadband

5. Mobile Broadband Before Windows 7 • No standard mechanism for device interface • Some devices appear as a network adapter • Some devices appear as a modem • No standard programming interface • Connection managers must be written for each type of device • Network Adapter • Modem ConnectionManager #N . . . Device #1 Device #2 Device #N ConnectionManager #1 ConnectionManager #2

6. New in Windows 7 • Simple out-of-box Connection Manager experience for mobile broadband • Similar to wireless local area network (WLAN), virtual private network (VPN), and dial-up • Driver model for mobile broadband devices • Mobile broadband API • Logo program for mobile broadband devices • Device Stage for mobile broadband

8. Connection Manager • A unified experience for managing dial-up, VPN, Wi-Fi, and mobile broadband connections • New for mobile broadband • Auto and manual connect • Operator branding • PIN and PIN unlock key (PUK)security configuration • Roaming configuration • Device provisioning

9. Mobile Broadband Driver Model • Supports packet-switched data connectivity over Wireless Wide Area Network (WWAN) Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA) devices • Is interconnect agnostic – works on USB, ExpressCard, embedded, and any other interconnect technology • Introduces new Network Driver Interface Specification (NDIS) medium for mobile broadband – NdisMediumWirelessWAN • Is designed for slow response AT command-based devices • Is based on NDIS 6.20 miniport driver model

11. Mobile Broadband Service • Is also called the WWAN service • Is a user mode session 0 Windows service • Implements auto-connect, auto-configuration, and diagnostics features • Manages mobile broadband devices, network, and connectivity • Provides SMS, PIN, and scanning functionalities

12. Control Path Functionalities • Mobile broadband driver model defines the following control path functionalities • Device state management • Connectivity management • Radio control • SMS • PIN • Provisioned contexts • Service activation • Vendor-specific extensions

13. Control Path Device Driver Interfaces (DDIs) • Mobile Broadband Service uses a Network Driver Interface specification (NDIS) object IDs (OIDs) for control requests (SET or QUERY) to MB miniport driver • Asynchronous semantics for slow control devices • Designed for AT command-response-based modems

14. Mobile Broadband API • Device-agnostic application programming interface to manage mobile broadband connectivity • COM-based API • Can be called directly from unmanaged applications (C++) • Can be called from managed applications (C#) through COM interoperability

15. Mobile Broadband API Functionality • Access to driver control path functions SMS PIN Custom activation Vendor-specific operations • Device management • Radio state management • Connectivity management • Profile management • Profile API provides branding opportunity for operators • Custom service activation • Is a pass-through API for vendor-specific service activation • Passes payload data through to the mobile broadband driver • Requires support from mobile broadband driver

16. Custom Features Connection Managersand other applications • Framework provides vendor-specific API to implement custom features • WWAN service provides a pass-through control path for Windows 7-based applications to communicate with MB driver • Usage examples • SIM Application Toolkit commands • Unstructured Supplementary Service Data (USSD) commands • Phone book commands • Voice commands • And more… SetVendorSpecific OnEventNotification Mobile Broadband Service NDIS_STATUS_WWAN_VENDOR_SPECIFIC OID_WWAN_VENDOR_SPECIFIC MB Miniport Driver

17. Mobile Broadband API Object Model API defines three types of COM interfaces • Manager object interface • Is the root of the object hierarchy • Provides methods to enumerate function objects • Provides a mechanism to register for change notification • Function object interface • Provides methods to manage mobile broadband functionality • Is divided into multiple interfaces based on functionality • Callback interface • Set of functions implemented by application to receive notifications • Asynchronous operation completion • State change notification

18. Logo Program for Mobile Broadband • 12 requirements, classified into four categories • For mobile broadband device vendors • Ensures the stability and reliability of the drivers • Drivers and updates can be delivered with Windows Update • For Connection Manager vendors and other software vendors • Creates a rich set of abstracted mobile broadband devices to target • For mobile operators and systems builders • Allows for the creation of rich, branded Device Stage experiences
