Large-scale IoT deployments are currently within our grasp technologically in the form of smart cities.
Smart cities have promised to make our lives more efficient. With connected devices and information controlled by an intelligent system, cities will never have traffic jams again. Connected technology can also make cities energy efficient with different sensors identifying waste. Despite the tech industry talking about it for a decade and a half, it has not come to fruition.
Most deployments focus solely on the distribution of hardware without considering the needs of the hardware. Because of this, deployments have failed or been long forgotten.
