1 Introduction to Intel® Pro Wireless Display As of writing (Jan 2014) Intel® Pro Wireless Display (Pro WiDi) technology is not yet intended for broad deployment into production at an enterprise. However, enterprises are increasingly aware of the benefits of Intel® WiDi and want to take advantage of these capabilities in the workplace. However, consumer and enterprise requirements are very different.
Intel vPro technology PCs are an essential component for Intel Pro WiDi but for clarity it is worth noting that it is not required that Intel® iAMT (Intel Active Technology Management) is activated or enabled on the target PCs. 1.2.1 Client Operating System It is recommended that the POC be run on Windows* 7 PCs. As of writing (Jan 2014) Intel Pro WiDi features on Windows 8 and Windows 8.1 are still under development. Note that the Intel WiDi application needs to be installed on Windows 7 and Windows 8.
the connection is simply for displaying content, which is usually not of a confidential nature (e.g. photos, movies and games). In most cases the displays are far enough away from public spaces that the wireless connection may not be intercepted. All day battery life is not as critical in a living room or home entertainment environment, so for consumers, Intel optimizations are positioned for their quality and performance improvements.
2 Intel Pro WiDi Requirements This chapter defines the overall requirements for implementing Intel Pro WiDi. Additional requirements information may be included in the setup sections for individual components. 2.1 Overview Intel Pro WiDi consists of several components, all of which are required to experience the full benefits of Intel Pro WiDi.
2.3 Infrastructure Requirements 2.3.1 IT Department The IT Department requirements are as follows: Updated Intel graphics drivers and Intel WiFi drivers: IT must install updated graphics drivers and Intel Pro WiDi drivers on all client computers.

3 Infrastructure Considerations This chapter contains some points to consider before deploying Intel Pro WiDi for the pilot. 3.1 WiFi-Direct You must enable WiFi-Direct in your environment. See Chapter 6. 3.2 Using Intel Pro WiDi with a VPN Depending on your infrastructure settings, you may need to connect to WiDi before initiating a VPN connection. 3.3 DFS Considerations For regulatory reasons, Intel Pro WiDi does not operate on WiFi channels reserved for radar use (also known as “DFS channels”).
4 Display Adapter Setup Until Intel Pro WiDi Certified Adapters are available, POCs will need to be run using an adapter designed for the consumer market. There are a number of adapters, TVs and projectors that support Intel WiDi but we strongly recommend using an adapter that has recent firmware available to ensure your POC is as effective as possible.
5 Client Setup This chapter describes how to set up the client platforms to deliver the Intel Pro WiDi remote display user experience. This is a “Best Known Configuration” that describes the intended outcome of the client setup process. When you have completed the client setup process, you should have a client system that is configured with the “Best Known Configuration.” 5.
Notes: 1. Both the Intel HD Graphics Driver and the Intel PROSet/Wireless Driver MUST be installed prior to installing Intel WiDi software to meet platform detection requirements in the Intel WiDi software. 2. Intel WiDi requires Microsoft .Net 4.0 framework to be installed prior to installing the WiDi application. 3. To perform a large-scale batch install using a script, see Section 5.2. The Intel WiDi software release is a single-file-based installer.
5.3 Uninstalling Intel WiDi Software Note: Perform this procedure only to uninstall Intel WiDi software if the installation process was successful. If the install procedure was unsuccessful, you do not need to uninstall it. To uninstall Intel WiDi software, do the following: 1. Go to Start > Control Panel > Programs and Features. 2. Select Intel WiDi. 3. Select the Uninstall option to uninstall the Intel WiDi. 4. Reboot the system to complete the uninstall process. 5.
6 Creating a WiFi Settings Package Creating a WiFi policy script for the client PC requires the Intel WiFi driver and Intel PROSet Administrators Toolkit to be installed. During the installation, select the Customize button and select all options on the next screen. Follow the installation instructions in Section 5.1, Step 2: Install Intel PROSet Wireless Software. Note: Perform the steps below on an IT Administrator computer, not on a client computer.

7 Intel Pro WiDi User Instructions 7.1 Connecting to a Wireless Display The first time you connect to a wireless display, you must “pair” your computer to a wireless display by exchanging a PIN. The second and subsequent connections use the stored pairing information to connect more quickly. 7.1.1 Pairing to a Wireless Display Use this procedure the first time a computer is connected to a wireless display. 1. Start the Intel WiDi application. 2.
Note: Note: The PIN is used to pair the computer to the specific wireless display. Note: Note: The wireless display times-out after approximately two minutes. If the wireless display goes back to the “Ready for connection.” screen, you must reselect the display in the application and click Connect. 4. Enter the PIN and click Continue. (The PIN shown below is only an example. Your PIN will be different.) 5. The wireless display connects with your computer.
7.1.2 Connecting to a previously Paired Wireless Display Use these steps for subsequent connections to a wireless display with which the computer has already exchanged a PIN. 1. Start the WiDi application. 2. Identify the wireless display to which you want to connect. Select the row with that display. 3. Click Connect. The Connection Successful confirmation screen displays. This is also referred to as the Connection Confirmation screen.
8 Troubleshooting 8.1 Intel Pro WiDi Logging Use the information in this section to set up logging for Intel Pro WiDi. 8.1.1 Installer Logging During installation, the Intel WiDi installer creates a MSI Install log and WDL log in the following location: C:\Users\\AppData\Local\Temp\MSI.log C:\Users\\AppData\Local\WiDiSetupLog..wdl 8.1.2 Enabling Session Runtime Logging 1. Exit the Intel WiDi application. 2. Launch Regedit.exe. 3.
Issue Solutions The PC Doesn’t Seem to be Connecting to the Adapter At the PC, verify that WiFi is switched on. Antivirus / Firewall software may be blocking Intel WiDi software. Add the Intel WiDi application (“widiapp”) to the software’s white list. Disconnect from the WiFi network and connect to Intel WiDi without a WiFi connection. Issue Solutions Wireless Network Reception is Poor Best Known Methods (BKMs) Disconnect and exit VPN and connect to Intel WiDi without a VPN or WiFi connection.
Issue Solutions PC Desktop Does not Display on TV Verify that the correct security code was entered into the Intel WiDi Software for the adapter you are connecting to. Reset the adapter. Verify that the PC screen is set to one of the following supported screen resolutions; 1280x720, 1280x768, 1280x800, 1366x768, 1440x900, 1600x900, or 1920x1080. Issue Solutions I can’t get a good picture using 2.4GHz Try changing the WiFi channel used by Intel Pro WiDi. In general, 2.
9 Conclusion 9.1 Intel Pro WiDi POC management Intel Pro WiDi is an exciting technology with great potential to improve user experience in the enterprise. As Intel Pro WiDi matures and Pro WiDi Certified adapters become available these potential opportunities can be made available in production deployments. Until then, it will be important to explore what Intel WiDi can provide while managing expectations amongst IT and the user base with respect to what can be delivered today.
Appendix A Known Issues Issue Description DFS Roaming Windows 7: Enable DFS roaming either through the Intel PROSet IT Admin tool, or by creating a registry key, shown below: [HKEY_LOCAL_MACHINE\SOFTWARE\Intel Corporation\Intel WiDi\Enterprise] "DFS Roaming Enabled”=dword:00000001 Windows 8: DFS roaming is not yet functional. To avoid DFS errors, set the NIC on the client platform to connect only to 2.4 GHz. This can be accomplished by setting the WiFi NIC to 802.11g.
Issue Description VPN The WiDi subnet should be excluded from the VPN routing table. If NOT using the exclude "Local LAN Access" capability, add a static exclusion to "192.168.x.x" in order to support Intel WiDi. Note: Note: This might be considered a security risk and personal firewall settings should be modified to allow only specific ports\protocols on this subnet (ingress\egress). If using "Local LAN Access", verify that the VPN client can adjust to new subnets post connection establishment.
