Cool demonstration with GNU Radio?

Hi guys,

I just been handed a USRP and have 9 weeks to do something cool with it
for a presentation.

I was wondering what I do with it to have a tangible demonstration
rather than just explaining what I’ve done with it.

At first I was thinking in operating the FM band and do some different
modulation schemes and show if the USRP or radio will or will not play
music.

But I can only operate in the 2.4GHz band which apparently is the same
band as WiFi.
I was wondering if it was possible to generate a signal modulated by
OFDM(I think that’s the same modulation scheme as WiFi) and bring it
close enough to the router and interfere with the router’s signal enough
to break a laptop connection to the router?

What are some cool demonstrations that I could do with the USRP?

Thanks,
Tyro
