When tackling your next IoT project, it’s worth casting an eye over the cellular LPWAN offering. While LoRaWAN seems low power on paper, researchers have seen wild variations in battery life with real-life deployments. LTE-M and NB-IoT are both very competitive when it comes to power budgets and offer a range of other benefits on top. But, like all good things, they have their own host of challenges to deal with.
