Internet of Things
The Internet of Things (IoT) seamlessly interconnects objects, products and machines. The resulting benefits include increased productivity, reduced waste of resources and enhanced security. In addition, IoT enables completely new services and business models. The InES has broad and proven project experience in designing reliable networks of low-cost, energy-efficient IoT nodes, in authenticating those nodes and in providing the technology needed to operate the various connections securely.
