My name is Brandon. I am recently doing my thesis about the 3G QoS using the OPNET. However, none of us here hav the experience of using this software. So is anyone doing the same title or research before? I will be really appreciate if u guys can send me some example of building up the network and also some simulation results using the OPNET software. Please email to me if possible. My email is firstname.lastname@example.org.
