Bluetooth mesh makes quintessence of smart technology

Making smart homes has recently become an inevitable trend. Many communication technologies can be applied to control the house such as Wifi or Zigbee. While each technology has its plus and minus, Bluetooth mesh is considered as one of the most effective and reliable methods of sharing information in large networks.

Overview

Bluetooth mesh is a computer mesh networking standard based on Bluetooth Low Energy (BLE) that allows for many-to-many communication over Bluetooth radio. BLE was invented in 2010 to solve the problems of connectivity and data transmission in the period of rapid development in the field of Internet of Things (IoT).

Mesh networking is optimized for creating large-scale device networks. It is ideally suited for control monitoring and automation solutions that require tens, hundreds or thousands of devices to communicate with one another.

Advantages of Bluetooth mesh

Self-healing capabilities and extended range 

The mesh works under one principle called a flood network. Any messages sent by all devices are then forwarded through other devices to be delivered to the desired device, which greatly increases the connection distance up to hundreds of meters between nodes (known as devices in the mesh).

In addition, the network connection feature enables the other devices to continue transmitting messages even if one node loses connection without affecting all the system.

A device with standard bluetooth connection protocol can connect to hundreds of other devices with the same protocol. This feature also makes it easy to expand the network.

The network is easily extended in BLE mesh.

This protocol also does not require a central controller. Instead, users can take mobile phones as an intermediary device to participate in the network, which reduces costs as well as increases the usability of the system.

Low energy consumption

Bluetooth mesh is a mesh networking standard based on BLE technology, which is designed to provide low cost and energy consuming connectivity.

The electronic devices using BLE mesh have longer lifespan than before.

Specifically, devices in the network only need to use the amount of energy to send data to a nearby device, and then that device will continue to transmit while the device does not always need to broadcast continuously. Some devices that are not used very often only need to send and receive data every few hours. This advantage will be beneficial to sensors or battery-powered devices such as electronic locks.

Therefore, Bluetooth mesh is the ideal connection protocol standard for industrial IoT cases, especially lighting, because of its scalability, low power cost, reliability and good performance. It enables multi-device communication and is optimized for creating large-scale device networks.
