As the documentation says, all the processing from physical to protocol layers is done by the PC. Could anyone experienced in wireless technologies explain what is the software radio frontend worth 2000$ actually doing?
A USRP costs almost $2,000 because it is completely general-purpose, modular, and customizable. It's more flexible than you really need, but if you're doing a one-off project it's cheaper than designing a custom radio.
so right now the only use of it is to get the raw packets from ethernet, convert to analog with required power and just release it over the metal? I may be wrong here.. not an RF expert
