This is no way comparable to a USRP. Receive only, 80Khz bandwidth, and who knows how long lock time for frequencies. It's a barely software defined radio- more of a wide band scanner.

It's a cute receiver. You can't build a GSM base station with it.

USRP is much more sophisticated and capable. Unfortunately it is pretty expensive.

Anyone knows of a reasonably priced board suitable for GSM implementation (has to have both receiver and transmitter)? Perhaps a combination of low cost evaluation boards? Baseband should be relatively easy. It's the RF (down and upconvertion/amplification that are more difficult to find).
