The Bluetooth Special Interest Group announced Bluetooth Mesh in July 2017, bringing new possibilities for networking and inter-device communication, making end users and manufacturers highly expectant, and homes, offices and roads are only available. Immediately benefit from the tip of the iceberg. Innovative, forward-thinking manufacturers are beginning to look into further expansion of Bluetooth Mesh applications for cross-factory and manufacturing facility deployments to improve efficiency, productivity and Synchronicity.
According to reports, the Mesh network is not a single solution for all device online applications. As Mesh technology becomes more and more important in other wireless applications, Bluetooth Mesh will flip the status quo. This new software layer will replace the traditional Mesh function. The Point-to-communicaTIon method allows devices with built-in Bluetooth chips to communicate with Points of Contact.
The Smart Home network wireless protocol Thread, as well as the short-range, low-data-enabled wireless standard Zigbee, will be the next step in the development of Mesh technology. The IoT devices with built-in Bluetooth chips in smart homes all use point-to-point communication, so users can only manage a single device at a time.
Bluetooth Mesh's Hyper-connecTIvity feature allows users to remotely manage any Bluetooth-enabled device in the home from a mobile phone, including garage doors, kitchen appliances, lighting, Nest cameras, Wireless speakers, TVs, smart thermostats, etc.
In addition, Bluetooth Mesh is also suitable for office and smart vehicle applications. Managers can remotely control office devices, including office door locks, fixtures, and temperature, with a variety of built-in Bluetooth chips. Vehicles equipped with IoT sensors can communicate effectively with each other or with the surrounding infrastructure to monitor any driving safety-related things, such as detecting traffic signs that are approaching, and letting the driver know how much time there is before the change of the number; or Detecting vehicles passing by, allowing the driver to avoid possible collisions when changing lanes.
Product development engineers must take advantage of Bluetooth Mesh to meet the expectations of manufacturers and end users. First, in order to achieve the simplicity and low cost of a large number of deployments, product development engineers must ensure that these devices are manufactured at low cost and mass production in order to take advantage of the ease of replication of Bluetooth Mesh.
Secondly, because devices connected by Mesh networks must be widely deployed in a variety of locations, functions, and applications, engineers must consider small size targets when designing these devices. Finally, in order to avoid Dark Spots on Mesh networks, engineers must prioritize low-power usage and high-power reliability to ensure that the connected devices are always on (Always On).
There are two types of Mesh networks. The concept of routed Mesh is similar to telephone communication. The connected independent devices have designated communication paths, and the communication between specific devices follows the fastest specified path between two points. The concept of flooding Mesh is similar to communicating through a loudspeaker. Each device on the network can simultaneously send signals to all Bluetooth-connected devices in an area.
The prototype of the Bluetooth Mesh standard is a flood-based protocol, but it is not valid because of the flood of communication between devices that need to be managed and the inefficient use of energy. The latest Bluetooth Mesh proposes a Managed Flood that combines the advantages of routing and flooding, allowing similar devices to communicate with each other in the form of blankets.
