Mesh network

A mesh network is a communication system in which all nodes (devices) are interconnected and can independently relay data. This decentralized structure is particularly useful in building automation, as it creates a robust and flexible infrastructure for wireless communication. Even in case of disruptions, the network remains functional by utilizing alternative communication paths between devices.

Technically, a mesh network operates through data forwarding, where each node acts both as a transmitter and as a receiver. This architecture enables the self-healing function: When disruptions or failures occur, the network automatically reroutes data through alternative paths, ensuring stability and functionality. Mesh technologies like Bluetooth Low Energy (BLE) and Zigbee are specifically designed for energy-efficient and reliable communication. They support a wide range of connected devices such as sensors, actuators, or gateways in complex building structures.

Mesh networks are successfully employed in many areas of building automation. In office buildings, they connect lighting and climate systems that respond to real-time data to save energy and enhance comfort. In warehouses, they allow wireless monitoring and optimization of production processes, along with efficient resource utilization. Residential buildings use mesh networks for smart security and comfort systems that can be flexibly controlled and adjusted.

The functionality of mesh networks is enhanced by technologies such as cloud-based platforms and Over-the-Air (OTA) updates. These enable continuous updates and expansions of network systems without requiring physical intervention. New devices can be seamlessly integrated, and existing network components can be regularly updated. Mesh networks offer high scalability, which is particularly advantageous for retrofitting older buildings.

Mesh networks are essential for modern building automation, ensuring reliable communication between connected systems and devices. Their decentralized and resilient structure guarantees efficient and scalable communication, vital for the control and optimization of smart buildings.
