The Internet of Things (IoT) has dominated the huge CeBIT technology show in Hanover, Germany this week, and smart lighting has been particularly prominent. Huawei launched a smart city solution that pledges to slash lighting energy bills by 80% though ‘multi-level intelligent control’. This would see clusters of lights connected to local hubs using the 6LoWPAN short range wireless technology. The hub would act on information from sensors to switch lights on and off, or dim them, depending on the weather and the level of activity near the lamp. These sensors can then be used for other smart city applications, following the increasingly common approach of using street lights as the infrastructure framework for a range of services. “Lighting IoT…
