Our offices are equipped with sensors with LoRa radio's. We're partnering with a local cell service provider (proximus.be) who are upgrading their base stations to be LoRa base stations and we're a pilot installation because we're developing software that does things with the sensor data (smart office type stuff, like adaptive cleaning schedules based on space utilization). The sensors are pre-configured for their network. You stick them to the wall, pull a latch, and they connect directly to the public base station, no additional hardware involved. Surprisingly, it works, and they're claiming five years battery life. There are some downsides though. The sensor+radio combo's are custom orders for now, meaning they take too long to arrive and are too expensive. That issue will get solved over time. They also have an extremely low data rate. A single set of values every 15 minutes. That issue probably won't be solved. Still, you can learn a lot from a CO2 reading or a door opening counter reading even if it's only every 15 minutes. The hard bit is the intelligent software that processes the data. If anything is the achilles heel of IoT it's that lots of data does not necessarily lead to any insights.
