This document discusses crowd sourcing smart cities using low-power wide-area networks (LPWAN) like LoRaWAN. It outlines how The Things Network (TTN) is being used to build skills and inspire innovation in Norwich by experimenting with LoRaWAN gateways and developing inexpensive sensor nodes. Current and potential projects using the TTN in Norfolk and Suffolk are described, including air quality monitoring, parking space monitoring, and integrating sensor data with platforms like Azure and IoT Central.
