This time I went looking for radio modems. The robot will have conventional WIFI and GPRS/3G/LTE access, but I thought that as a more general purpose, fail-safe and cheaper alternative (3G is expensive), It would be neat to have a FM radio on board. Just look at all the goodies!

I made sure to hide my VISA card someplace safe first.
