“If you build it, he will come,” whispered a disembodied voice in the 1989 fantasy-drama Field of Dreams. In time, Kevin Costner’s character grew convinced that “it” was a baseball field even though the “he” remained a mystery. So Costner plowed under his corn field and built the baseball diamond which he painstakingly tended until the arrival of whatever came next. The founders of The Things Network (TTN) are playing a similar game. This time, however, “it” is a subscription-free, community-owned LoRaWAN network that now blankets Amsterdam, and the “he” could be any number of possible solutions enabled by the diverse and unimaginably vast array of wireless and battery-operated things coming to our cities.
