overview

At VVDN, we design and deploy end-to-end IoT connectivity solutions across industries, leveraging both wired and wireless protocols to enable reliable, secure and scalable communication.

Our expertise spans integration of connectivity protocols into a wide range of IoT devices—including sensors, actuators, gateways and edge controllers. We work across the entire stack, from RF design and embedded firmware to cloud connectivity.

Additionally, our in-house labs enable extensive interoperability and compliance testing, ensuring flawless real-world performance and seamless data exchange between devices.

From short-range wireless (UWB, Zigbee, BLE) to industrial wired networks (PROFIBUS, EtherCAT, Modbus) and cloud protocols (MQTT, OPC UA)—VVDN ensures that your connected devices perform reliably at scale.
