Once, many years ago, I stayed on the 62nd floor of the Westin Peachtree Plaza in Atlanta, Georgia. This was in the age when the price of a hotel room was directly correlated with the price of the WiFi service, and as a high school student I was not prepared to pay in excess of $15 a day for the internet. As I remember, a Motel 6 that was not blocks away but within line of sight ended up filling the role. But even up there, 62 floors from the ground, there was false promise: Free Public WiFi.

I am not the first person to write on this phenomenon, I think I originally came to understand it as a result of a 2010 segment of All Things Considered. For a period of a few years, almost everywhere you went, there was a WiFi network called "Free Public WiFi." While it was both free and public in the most literal sense, it did not offer internet access. It was totally useless, and fell somewhere between a joke, a scam, and an accident of history. Since I'm not the first to write about it, I have to be the most thorough, and so let's start out with a discussion of WiFi itself.
