ZigBee mesh‘s usefulness for IoT is partly due to the fact that it is an open standard. The same products can be used all over the world, which gives customers a large selection of available option. The high competition between products and producers means that the created solutions are innovative, characterized by high quality and give customers a considerable choice. Many suppliers of cooperating elements of this ecosystem mean that they are not limited to any specific brands or specific semiconductor manufacturers.
Competitiveness of ZigBee based solutions
With a maximum data bandwidth of 250 kbps at 2.4 GHz, ZigBee is slower than other popular wireless standards such as Wi-Fi or Bluetooth, but it doesn’t matter in typical sensor applications. ZigBee Mesh is designed to send small data packets at relatively long intervals, which is usually sufficient to collect data from temperature sensors, safety sensors, air quality monitoring systems and similar subsystems. In the meantime, the low bandwidth affects the low power needed for the system to work, so that ZigBee nodes can usually work for many years on a single AAA battery.
With low power consumption, ZigBee supporting products typically have a short transmission range – typically from 10 to 15 meters, and the signal they emit is easily disturbed by obstacles on the route, or changes in the environment. However, the beauty of ZigBee devices lies in their work as part of a lattice topology network, where each of them transmits signals between themselves over a total of longer distances. The grid topology also means that damage to a single device will not stop the entire network, as communication can simply be redirected.
Industrial use of ZigBee Mesh
One of industrial IoT devices, supporting ZigBee Mesh technology is eModGATE from TECHBASE. Economical, ESP32-based solution can serve as an end-point in any installation or works well as a gateway, gathering data from scattered sensor mesh across the installation.
