WLAN Toolbox

Simulate, analyze, and test WLAN communications systems


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 IEEE 802.11ax/ac/ad/ah and 802.11b/a/g/n/j/p standards. It also provides transmitter, channel modeling, and receiver operations, including channel coding (BCC and LDPC), modulation (OFDM, DSSS, and CCK), spatial stream mapping, channel models (TGay, TGax, TGac, TGah, and TGn), 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 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.

Get Started:

Waveform Generation

Generate a variety of standard-compliant Wi-Fi waveforms.

Supported 802.11 Standards

Generate IEEE 802.11ax/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.

Generating DMG, S1G, VHT, HT-mixed, and non-HT waveforms.

PPDU Packet Formats

Specify multiple formats (HE, VHT, HT-mixed, non-HT, DMG, S1G, OFDM, DSSS, and CCK) and generate each individual preamble and data field.
