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, authenticating those nodes, and providing the technology to operate the various connections securely.

Our Services

Do you want to network your components wirelessly and energy-efficiently? We have proven project expertise with Bluetooth Low Energy (ble), Thread/ZigBee, proprietary Sub-GHz technologies, LoRa, NB-IoT, NFC as well as WiFi and Mobile Communications. We support you in the implementation of intelligent, scalable networks with low energy consumption.
