this answer just came from ettus : ---------- The USRP2 can sample roughly 30MHz of bandwidth. I don't off the top of my head know what the single channel bandwidth for GSM1800 is, but you can use the 30MHz as a rough estimate of the capabilities of the USRP2. ------------ so to capture GSM1800 ( 2*75 ) we need at least 5 USRP2 working parallel , without any FPGA development
