Good question

The API to calculate SNR in IEEE802.11 module can be found in ErrorModel.h file calculate_snr(double dReceivedPower/*in dBm*/,double bandwidth/*In MHz*/) For Example, calculate_snr(pdbm, phy->dChannelBandwidth); Some more information is available in https://support.tetcos.com/en/support/solutions/articles/14000095868-how-can-i-get-plots-for-snr-in-netsim-

You can look at this earlier post https://www.researchgate.net/post/How_to_get_RSSI_SNR_and_BER_for_wireless_nodes_in_NetSim

SNR for every packet received cannot be got from the results window. That only gives aggregate results. You would need to add code to print the SNR to a log file. I don’t think an API is required since the SNR is anyway being calculated. It just needs to be printed out.

Is there someway to obtain this SNR data in NetSim without having to modify the code? Can it be got through some setting in the GUI or config file?

In the most recent NetSim release, v13.3, radio measurements can be recorded simply by enabling the corresponding checkbox. After simulation, the CSV log file, which can be opened with Excel, will contain a detailed record of the Signal-to-Interference-plus-Noise Ratios (SINRs) for various User Equipment (UEs) from different gNBs.
