TOL-008T

Certifying wireless devices using the Windows Hardware Certification Kit

Agenda• New and improved mobile broadband (MB) and

wireless LAN (WLAN) certification values• Improvements in the Windows Hardware

Certification Kit (HCK)• Guidance on testing

You’ll leave with examples of how to• Create high-quality MB and WLAN devices using the

new and improved certification values• Use the improved Windows HCK for MB and WLAN

testing • Take advantage of testing guidance

New and Improved Mobile Broadband Certification Values

• NDIS 6.30• Sleep/resume reliability improvements• Power management

• MB class driver• Power and performance• Multi-career/multi-mode• Extensible Authentication Protocol (EAP)

subscriber identity module (SIM)• Unstructured Supplementary Service Data (USSD)

New and Improved Mobile Broadband Certification Values

• USB selective suspend• Improve overall system power efficiency for long active

and idle battery life on mobile platforms while maintaining system responsiveness

• Reference• Support NDIS 6.30 WWAN specification

NDIS 6.30

• Microsoft to develop a generic driver for devices conforming to device interface specification

• The MB class driver provides the following value• For independent hardware vendors (IHVs)• Reduced driver development, deployment, and maintenance

costs• For telecommunication companies (telcos)• Simplified network certification • Faster time-to-market for new products

• Reference• WWAN device firmware presents a conformant interface

Mobile Broadband class driver

Improvements to Mobile Broadband testing within the Windows HCK

Key improvements

• Test Authoring and Execution Framework (TAEF)–based execution• Ability to run individual tests, test groups, or entire suite

• Reduced execution time• Execution time reduced by 70% for MB test content

• Improved documentation• Test documentation providing detailed view into test

content• Improved logging• Text in log files maps directly to test documentation

Mobile Broadband testing guidance

Mobile Broadband Windows Certification Program• Overview• Based on Test Automation and Execution Framework

(TAEF)• Single-machine topology

• Testing Client• Computer running Windows 8• Mobile Broadband device

Key testing areas• Basic MB functionality • MB class driver compliance• Power and performance• NDIS 6.30 compliance• USB selective suspend• Wake support• Multi-career/multi-mode (if implemented)• Extensible Authentication Protocol (EAP) subscriber

identity module (SIM) (if implemented)• Unstructured Supplementary Service Data (USSD)

(if implemented)

Walk-through of Mobile Broadband testing

Demo/Example

Step 1: Create a project

Step 2: Select Machine Pool & Devices/Systems

Step 3: Select Tests and Run Selected Tests

New and Improved Wireless LAN Certification Values

• Wi-Fi Direct• Power and performance• NDIS 6.30• 802.11w – Protected Management

Frames• Wake on wireless LAN

New and improved WLAN certification values

• Improve wireless device connectivity experience• Based on the Wi-Fi P2P (draft) specification • Integrate with Windows 8 user experience

framework• Reference• Support two Wi-Fi Direct ports concurrently• Device should be able to support being a group owner (GO)

on each Wi-Fi Direct port concurrently• Device should be able to support being a GO one Wi-Fi Direct

port and a client on the other Wi-Fi Direct Port concurrently • Support at least four clients being connected

simultaneously to each running Wi-Fi Direct group owner on the device

• Support infrastructure port concurrently with the Wi-Fi Direct ports

Wi-Fi Direct

• Improve Wi-Fi power efficiency for long active and idle battery life on mobile platforms while maintaining system responsiveness

• Minimize frequency of device interrupting CPU, allowing for maximum CPU idle time

• Dynamic power saving mode based on user activity to maximize power efficiency of the system

• Reference• Power Save Mode (PSM)

• Wi-Fi driver must support the detection of Power Save Mode

• Wi-Fi offloads• Wi-Fi profile (infrastructure profile) offload• Wi-Fi direct profile offload

• Interrupt/DPC/indication reduction• Wi-Fi device interrupt/DPC reduction (1.x ISR/packet)

• Networking offloads and selective suspend• Wi-Fi device must support NDIS offloads• USB selective suspend

Improvements to WLAN testing within the Windows HCK

Kit improvements• Overview• TAEF-based tool for measuring Deferred Procedure Calls

(DPC) and Interrupt Service Routine (ISR) frequency and duration

• Common use cases• Finding overactive interrupts• Finding long DPC interrupts• Finding DPC “storm” or bursts

• Where to find it• Available in Windows HCK and Windows Driver Kit (WDK)

WLAN testing guidance

Wi-Fi Windows Certification Program

• Overview• Based on NDISTest

framework• Multi-machine topology

• Testing Client • Three machines –

TestSoftAP, device under test (DUT), system under test (SUT)

• AP w/ 802.11w support NDISTest Client
