The Universal Software Radio Peripheral product family allows you to create a software radio using any computer with a USB 2.0 or Gigagbit ethernet port. Various plug-on daughterboards allow the USRP and USRP2 to be used on different radio frequency bands. Daughterboards are available from DC to 5.9 GHz at this time. The entire design of the USRP family is open source.
The USRP and USRP2 work with GNU Radio, a free-software (open source) framework for the creation of software defined radios. GNU Radio works on Linux, Windows, Mac OSX, FreeBSD and NetBSD (see FAQ for more details).
