WLAN Toolbox provides standards-compliant functions for the design, simulation, analysis, and testing of wireless LAN communications systems. It includes configurable physical layer waveforms for the IEEE® 802.11 family of standards. It also provides transmitter, channel modeling, and receiver operations, including channel coding, modulation, spatial stream mapping, and MIMO receivers.
The toolbox provides reference designs to help you perform baseband link-level simulations and multi-node system-level simulations. You can generate waveforms and customize test benches, either programmatically or interactively, using the Wireless Waveform Generator app. You can generate and parse common MAC frames. You can also perform signal measurements such as channel power, spectrum mask, and occupied bandwidth, and create test benches for the end-to-end simulation of WLAN communications links.
You can study the effects of RF designs and interference on system performance. Using WLAN Toolbox with RF instruments or hardware support packages, you can connect your transmitter and receiver models to radio devices and verify your designs via over-the-air transmission and reception.
Generate IEEE 802.11be/az/ax/ac/ad/ah/j/p/n/g/a/b waveforms. Use generated waveforms to test Wi-Fi systems and as a golden reference for implementation.
Specify multiple formats (HE, VHT, HT-mixed, non-HT, DMG, S1G, OFDM, DSSS, and CCK) and generate each individual preamble and data field.
Generate WLAN waveforms interactively. Add RF impairments such as AWGN, phase offset, frequency offset, DC offset, IQ imbalance, and memoryless cubic nonlinearity. Visualize results in constellation diagram, spectrum analyzer, OFDM grid, and time scope plots.
Characterize and simulate TGay, TGax, TGac, TGah, and TGn multipath fading channels.
Perform link-level BER, PER, and throughput tests.
Apply beamforming to improve link-level performance. Apply transmit beamforming to focus energy towards a receiver. Use receive beamforming to improve the SNR by pointing a receiver's main beam towards transmitter.
Perform transmitter modulation accuracy as well as spectral emission mask and flatness measurements.
Perform receiver minimum input sensitivity tests to verify compliance with IEEE 802.11 standards
Perform frame synchronization, frequency offset correction, channel estimation and equalization, and common error phase tracking. Demodulate and decode signaling and data fields.
Recover 802.11 OFDM non-HT based beacon packets.
Parameterize, generate, and recover various IEEE 802.11ax/az/be packets.
Specify resource unit (RU) allocation. Configure various combinations of OFDMA and MU-MIMO transmissions.
Generate IEEE 802.11MAC frames (MPDU, AMSDU, and AMPDU) and verify the contents of MAC frames are as expected.
Parse and decode 802.11 MAC frames.
Model a WLAN network with multiple nodes including MAC and PHY layers and a shared communication channel.
Use PHY layer abstraction to speed up system simulations. Develop link quality and performance models.
Compute system-level throughput metrics. Model traffic scheduling and characterize the effects of interference.
Use MATLAB to acquire and analyze over-the-air signals received via RF instruments or SDR hardware.
