System-Level Simulation
WLAN Toolbox™ system-level simulation capabilities enable you to model communication links with multiple nodes. The simulations operate across a protocol stack that includes physical (PHY), medium access control (MAC), and application layers (APP). You can measure quantities such as throughput, latency, interference, and packet loss at the node and network levels. You can also simulate and investigate the coexistence of WLAN signals with Bluetooth® signals.
The toolbox provides you with these capabilities:
Abstracted PHY or full PHY simulation
Interference modeling
Application traffic pattern modeling using file transfer protocol (FTP), On-Off, Video, and voice over internet protocol (VoIP) traffic models
Node mobility support using random waypoint mobility model
Run multiple independent simulations in parallel
