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.
Waveform Generation and Analysis
Generate and analyze standard-compliant Wi-Fi® waveforms. Use the Wireless Waveform Generator and Wireless Waveform Analyzer apps to configure, generate, and analyze various IEEE 802.11™ waveforms. Visualize results in constellation diagram, spectrum analyzer, OFDM grid, and time scope plots.
Link-Level Simulation
Simulate WLAN end-to-end wireless communication links. Incorporate transmitter, channel modeling, and receiver operations. Apply channel models and perform link-level simulations for various IEEE 802.11 standard versions. Analyze link performance by computing packet error rate (PER), bit error rate, and throughput metrics.
Test and Measurement
Model and test RF transceivers in the presence of noise and interference. Perform transmitter measurements, including modulation accuracy, spectral emission mask, and flatness. Test receivers using minimum input sensitivity compliance metrics.
Wi-Fi 8
Generate standards-compliant IEEE 802.11bn waveforms. Build an end-to-end link-level simulation and measure the packet error rate of a Wi-Fi 8 link. Model 802.11bn PHY innovations such as enhanced long-range packets, unequal modulation, intermediate MCS values, distributed-tone resource units (DRUs), and double-length LDPC codes.
Signal Recovery
Detect and decode WLAN packets. Recover the packet format parameters from the preamble fields to decode the data field and the MAC frame. Perform frame synchronization, frequency offset correction, channel estimation and equalization, and common error phase tracking. Demodulate and decode signaling and data fields.
AI, Positioning, and Sensing
Apply AI techniques to localize and detect features over Wi-Fi networks. Use a convolutional neural network for wireless sensing by using the channel state information. Train and test a deep neural network for high-precision positioning of multiple stations based on fingerprinting.
