I would recommend NetSim. The 5G library details is available in https://tetcos.com/5g.html

I find NetSim to be the tool of choice in 5G simulations, you may want to give it a try.

I agree with Vincent O. Nyangaresi and you can look at some Q & A on this

You can collect some 5G cellular network data from mobile phones using apk applications such as NetMonitor Pro, G-NetTrack.

We use NetSim for 5G simulations. It covers FR1 and FR2 as well as MIMO and beamforming.

Many thanks to everyone.

Is there a free version of NetSim that I can use for my research?

Mohammad Alquraan Your university should be able to get a trial version. Please see https://tetcos.com/contact.html

I recommend the NS3 tool.

I recommend the NS3 or NetSim for 5G simulations..

My suggestion is NetSim (see https://tetcos.com/5g.html)

I would recommend NetSim (https://tetcos.com/5g.html) which is a popular 5G simulator. It supports both Sub 6 GHz and mmWave, as well as advanced features such as MIMO, Beamforming, Interference, etc. The GUI is minimalistic and easy to use while their support has a merited reputation for competence.

I would suggest NetSim (https://www.tetcos.com/5g.html). I am currently working on performance optimization for 5G networks using netsim. GUI is minimal and it supports a lot of advanced features.

I would like to thank you all for your recommendations, they really help me.
