WLAN Toolbox

Simulate, analyze, and test the physical layer of WLAN communications systems


WLAN Toolbox™ provides standard-compliant functions for the design, simulation, analysis, and testing of wireless LAN communications systems. The toolbox provides 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, modulation (OFDM, DSSS, and CCK), spatial stream mapping, channel models (TGax, TGac, TGah, and TGn), and MIMO receivers.

You can generate multiple types of signals, including high-efficiency (HE), very-high-throughput (VHT), high-throughput (HT-mixed), legacy (non-HT), directional multigigabit (DMG), and sub 1 GHz (S1G). 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.

The toolbox provides reference designs to help you explore baseband specifications and study the effects of RF designs and interference sources 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.
