So, I'm trying tomake a system where nodes communicate, not on set channels, but on as much of the spectrum as they can use based on the level of interference. For example, we know that 802.11 divides the spectrum into 13 channels with the center frequencies set at 5MHz apart. In my ideal situation, a network with only two nodes would be able to use the entire spectrum to send data, a network with 4 nodes and two transmissions would divide the spectrum in half for each transmission, and so on and so forth.
In order to do this, I need to be able to scan for interference at specific channels/frequencies to determine whether or not they're available. Before I get too deep into the project, is this even possible with the USRP motherboard and the RFX2400 transceiver board? I know we have the RSSI circuit onboard, but I don't know on which frequencies it scans.
