Alien Harry Solomon (AKA French Stewart) experienced minor convulsions whenever the chip implanted in his brain started to transmit an "Incoming message from the Great Big Head" in the TV show 3rd Rock from the Sun. How 1990s! The March 2012 South by Southwest (SxSW) Interactive Conference in Austin, TX, introduced homeless human beings as wireless access points. Encountering challenges with your wireless signal? Just dial up a human wearing a T-shirt that says, "I'm a 4G hotspot." No alien force needed.
