Mesh Technology

Mesh communication is a truly novel technique to install site-wide wireless coverage throughout a facility without the need for dedicated base stations or routers. Each wireless sensor and actuator device acts as a router for neighbor devices. Self-installation, self-healing and redundant communication paths result from the mesh topology.

GreenPeak offers this mesh communication along with the ZigBee standard.

GreenPeak Low Power Routing

In addition, and unlike competitive mesh solutions, GreenPeak offers its unique and patented PeakNet Low-Power-Routing (LPR) communication stack. With the LPR stack, none of the devices require powering from the mains power supply, allowing for battery or even energy-harvested operation. This is achieved by using smart power-up/power-down and synchronization techniques that enable all mesh nodes to operate in a low-power mode without a battery or power cabling.

Self-Forming & Self-Healing Mesh Networks

The GreenPeak wireless network technology is designed for easy installation. Once a node is powered, it will automatically link to the wireless network. This ‘plug and play’ approach enables every technician to execute a 100% correct installation without the need to understand technical aspects of setting up a wireless network.

The PeakNet mesh network technology is also self-healing: nodes will automatically find alternative communication routes when signal quality decreases or when the infrastructure changes.

This diagram is a screenshot of a sensor management application for temperature monitoring and ventilation valve control. The management application runs on a PC and displays full status information of the wireless network, the temperature sensors and the valves. The right panel depicts all the devices in the network as grey boxes. The green links connecting the grey boxes are actual wireless communication link. It is clear from the exhibit that there are multiple paths from any device to any other device, which brings redundancy to the network. Messages hop from one device to another, forming a mesh network. The left panes show (from top to bottom) the temperature values, temperature graphs and status reporting of valves opening and closing.
