Notes
RFmx WLAN installs the following licensed products:
WLAN: Enables analysis of 802.11a/b/g/j/p/n/ac/ax/11be signals with standard-compliant physical layer measurements such as error vector magnitude (EVM), spectrum emission mask (SEM), transmit power (TXP), and more. RFmx WLAN supports single-user and advanced multi-user signals with flexible configurations, impairments, and measurement results per user.
WLAN MIMO: Enables analysis of 802.11n/ac/ax/be MIMO signals with standard-compliant physical layer measurements such as error vector magnitude (EVM), spectrum emission mask (SEM), transmit power (TXP), and more. RFmx WLAN supports single-user and advanced multi-user signals with flexible MIMO configurations, impairments, and measurement results per user/per chain/per segment.
Notes
If Windows Update is enabled, the installation process might hang if Windows Update interferes with the installation of Microsoft Visual C++ 2015 Run-Time. Visit ni.com/r/exjq43 for more information and steps to resolve this issue.
Use the serial number that is included with your software to activate RFmx WLAN. For more information on RFmx WLAN activation, refer to National Instruments Software Activation.

RFmx WLAN drops support for 32-bit user mode.
When you set the OFDMModAcc Noise Comp Enabled property to True:
Noise compensation applied limit check is now skipped if OFDMModAcc EVM Ref Data Symbols Mode property is set to Reference Waveform
EVM per Subcarrier and the EVM per Symbol traces now follow the noise compensation applied result
The following are the behavior changes in RFmx WLAN 20.7 from RFmx WLAN 20.6.
Obsoleted the RFmxInstr Configure Automatic SG SA Shared LO API and the RFmxInstr Automatic SG SA Shared LO property. Use RFmxInstr LO Source property with Automatic_SG_SA_Shared value instead.

Obsoleted RFmxWLAN OFDM Num HE-LTF Symbols property. Use RFmxWLAN OFDM Num LTF Symbols property instead.
Obsoleted public int FetchPpduInformation(string selectorString, double timeout, out RFmxWlanMXDsssModAccDataModulationFormat dataModulationFormat, out int payloadLength, out RFmxWlanMXDsssModAccPreambleType preambleType, out int lockedClocksBit, out int headerCrcStatus, out int psduCrcStatus) method. Use public int FetchPpduInformation(string selectorString, double timeout, out RFmxWlanMXDsssModAccDataModulationFormat dataModulationFormat, out int payloadLength, out RFmxWlanMXDsssModAccPreambleType preambleType, out int lockedClocksBit, out RFmxWlanMXDsssModAccPayloadHeaderCrcStatus headerCrcStatus, out RFmxWlanMXDsssModAccPsduCrcStaus psduCrcStatus) method instead.
Automating the Installation of NI Products
You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.
If the NI product you are installing uses Microsoft .NET 4.6.2, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.6.2 separately before you install NI software.
For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager manual.
Using NI Software with Microsoft Windows 11
Microsoft Windows 11 is the latest version of the Windows operating system and features significant changes compared to previous versions. For more information about NI support for Windows 11, refer to NI Product Compatibility for Microsoft Windows 11.
