Hello Tasnim,
The WLAN toolbox allows you to model model Wi-Fi links with multiple nodes through its system-level simulation. You can simulate protocol stacks that include PHY, MAC, and application layers. For more information on how to do the system-level simulation look at the topic pages and examples in the link here. For more information on the other modelling and features available in the WLAN toolbox you can look at the documentation here.
The 5G toolbox allows you to model multinode networks operating across a protocol stack that includes physical (PHY), medium access control (MAC), radio link control (RLC), and application layers by system-level simulations. For more information on how to do the system-level simulation look at the topic pages and examples in the link here. For more information on the other modelling and features available in the 5G toolbox you can look at the documentation here.
