If anyone is interested, I built a vaguely similar thing a few years ago [1]. The major difference is that it's restricted to the 2.4GHz bands, though the transceivers are modular and can be swapped out for broadband units. It's also MIMO capable, accepting up to 6 transceivers on a single PCI card. Being a little dated, the interface is PCI and size/speed of the FPGA is limited. Software is rudimentary, my ambition being to one day port GNUradio onto it. I've always intended to continue the development, but, so far, other things have intervened. Full design details are released under the GPL and contained in the downloadable thesis [2].
