Wireless Network Simulator in matlab 2023

- Why do the stations transmit to each other while there is no association among them?
- How the stations transmit to the access point while the traffic generation is one way?
please find the attached code"ex1_AP_STA.m" and output data of simulator "Simulation data.zip"

Hi Samar,
I understand that you are working with Wireless Network Simulator and have few queries regarding it. Regarding your first query, stations are not transmitting with one another directly as the topology of your wireless network is an Infrastructure BSS network. They are communicating with each other only via the Access Point (AP).
Regarding your second query, eventhough, the traffic generation of your simulation is one way, the stations transmit control frames such as RTS and Acknowledgement frames back to the AP as part of the protocol. Therefore stations transmit control frames to the access point.
The 'Simulation data.zip' contains the 'PHY' statistics of each node. To understand more about the different kinds of frames transmitted by the station to the AP, kindly look into the 'MAC' statistics of each node using 'statistics' object function.
>> sta1Stats = statistics(sta1);
>> sta1Stats.MAC
Please refer the below documentation to know more about 'statistics' object function.

In "802.11ax Downlink OFDMA Multinide System-Level Simulation" example with the following link https://www.mathworks.com/help/wlan/ug/802-11ax-downlink-ofdma-multinode-system-level-simulation.html
I changed the datarate from 100000 Kbps to 1000 Kbps. the AP throughput changed to be 4 Mbps. How the AP throughput is greater than the datarate? does this mean that this is the throughput of the 4 stations and I have to divide it over the number of stations to get the actual AP-STA pair throughput?
