Hello! I´m really new to gnu-radio. I installed the 3.0.4 version on my Ubuntu system finally and now I need some ideas, here is what I want to do: I want to use the USRP to sniff everything going on between 2 WLAN-PCMCIA Laptops on 2,4GH. How do I do that..? Does GNU Radio give me any tools making it possible to visualize this in any way?
This will not be possible at the moment. The USRP can transmit 8MHz of complex bandwith over USB 2.0, and a WLAN-Channel has a bandwith of 22MHz. You can sweep over the WLAN-Area and detect power to see if a range has traffic, but you won't be able to decode a lot.
See the archives of this list, it has been discusses a few time in the last year or so.
