"Hardware" is the part for transferring the packet on the wire and between the NICs and the PCs + the notifications that some packet arrived. "Software" is the part that handles the packet on both sides in, well, software: the NIC driver, the stack, maybe also some Application (ICMP pings are measured at stack-level in RTnet). > > I am now having a wireless lan card driver running in Linux.

We only have one card currently in RTnet, and that is experimental. Depending on your hardware, RTnet support can be feasible (there are also cards where it isn't), but you shouldn't pick it as a beginner's exercise.
