What are the types of simulations used in studying the wireless system? Briefly describe them?
Depends on what band you want to emulate. Open spectrum can be done simply using an access point. K-Band, Kr-Band, Sat systems etc... require specialized frequency generators as well as waveguides to support them.
Before you download anything, learn how to use Ping. it is a simple dos based command line for checking IP addresses on networks, and will be invaluable if you run into any problems setting up your coice of program.\nI have no idea which is best software to use. There are so many, given that almost all video conferencing software designed to work via internet will also work on a network. I once used a microsoft comms program that allowed me to talk to different people simultaneously, some of which were over internet, and others over network, in the same virtual "room".
