"48 bits at 1.5Mhz rate?"
That's 72Mbps, so you can just manage it with the best WiFi routers out
there.
Not so, Wifi are rated at burst data rate, not sustained rate.

Sure, the advertised data rate is something absurd like "300Mbps!" But go
read the link I provided -- the best routers absolutely do better than 70Mbps
*on average*. Obviously the speeds gets reduced as you move further from the
router or have other interferers that reduce SNR, but close-in something like
a Belkin N1 will do the job (see:http://www.smallnetbuilder.com/content/view/30238/96/) for under $200.

And you probably want his spartan FPGA to talk ethernet as well.
