Where nerd points really kick in is when you detach the antenna, insert a 6' cable, then mount the antenna bit on a satellite TV parabolic reflector to get WiFi from a mile away.
Except that, IIUC, it is illegal in many (all?) ITU member jurisdictions for an unlicensed individual to operate such an intentional radiator with an antenna with higher gain than that with which it manufactured. In some jurisdictions it might even be illegal to make the modification. (Of course, there wouldn't be much point in making the modification when you can't use the modified system anyway.)

Satellite dishes reflect microwaves, which are a sort of radio wave. Wifi uses radio waves IIRC slightly below the range of the microwaves (so, miniwaves maybe?),
WiFi typically uses spectrum around 2.4 GHz or 5 GHz, so very definitely microwaves. [Microwaves are typically defined as 1 GHz to 100 GHz; sometimes 300 MHz to 300 GHz.] FWIW The big old satellite television dishes were for signals around (very roughly) 5 GHz; If I remember correctly, the more modern dishes are for K_u band signals, which are more like (very roughly) 15 GHz.
[doublepost=1498504519][/doublepost]Trying to get myself back on topic: @ptitSeb What area of the software development for the Pyra do you expect to be working on? Do you expect to be able to shed some light on the 4 GB problem? Or will you we working with the software at a level further from the hardware?
