Bluetooth mesh network is ideally suited for control, monitoring, and automation systems where hundreds, or thousands of devices need to communicate with one another. (reference from： https://www.bluetooth.com/learn-about-bluetooth/recent-enhancements/mesh/) .
Since the Bluetooth Mesh device does not have the ability to directly access the Internet, a device with Bluetooth communication and networking capabilities is needed to realize the remote control function. This device is the Bluetooth Mesh Gateway. A Bluetooth mesh gateway is a IoT bridge for Bluetooth Mesh devices to connect to the Internet. Bluetooth Mesh devices use Bluetooth to make communication and cannot directly communicate with the cloud server. The commands sent from the cloud will be sent to the Bluetooth Mesh device through the Bluetooth mesh gateway. Also, the status of the Bluetooth Mesh device can also be reported to the cloud server through the Bluetooth Mesh gateway.
The main markets for Bluetooth mesh networks are building automation, wireless sensor networks and asset tracking. Why these three markets? Because most of these areas are indoor spaces, avoiding the need to establish a low-power wide-area network with outdoor base stations for long-distance transmission. Meanwhile, Bluetooth mesh network can deploy thousands of nodes, which solves the problem of insufficient transmission distance of traditional wireless networks. , so it can be deployed in large indoor spaces such as buildings, factories, hospitals, stadiums, etc. According to the introduction of Bluetooth SIG,
Bluetooth mesh was designed from the beginning to meet the strict requirements of commercial and industrial environments where performance, reliability, and security are of the utmost importance. Advanced commercial lighting control is one use case that has rapidly embraced Bluetooth mesh.
From the above introduction, we can see that BLE mesh network has expanded the way for smart buildings. When a smart building is deployed with the Bluetooth Mesh network, dozens, hundreds or thousands of BLE devices in the building can communicate with each other reliably and securely. After installing Bluetooth mesh gateways, it can help a smart building connect to the internet to realize building automation, so as to remotely control and link BLE devices.
How Exactly Bluetooth Mesh Network Help Realize a Smart Building
Imagine that on a winter morning, you drive to work. After passing through the company security system, the system automatically assigns a parking space to you. The number above the parking space automatically lights up, guiding you to park your car easily. Ane then, the space allocation system then immediately marks the space as occupied.
Smart Lighting Control
When you walking into the building, the sensor detects your presence and instantly identifies you through your wearable device. You walk into the elevator, ride to the second floor, and step out of the elevator. As always, you’re the first in the office again. When the elevator door opens, the lights will automatically turn on along the road from the elevator entrance to your office and kitchen. In order to save energy, other areas remain dark. See Bluetooth mesh lighting control introduction here!
Smart Temperature Control
You walk into the office and the door closes automatically. The lamps on the ceiling and on your table have been turned on and adjusted to the most comfortable brightness. You notice that the temperature seems to be slightly warmer, which happens to be your personal favorite temperature. As soon as you sit down, your computer automatically logs you in.
Reasons That the Building Become So Smart
Your day begins so smoothly, and the building automatically responds to your needs and even your preferences. All the systems work so efficiently, because a few months ago, the company installed a Bluetooth Mesh network. At the beginning, the mesh lighting system was installed first; later, presence sensors, environmental sensors, wireless heating and air conditioning, and parking management systems were added to the mesh network one after another. As a result, the company has saved a lot of electricity and heating bills, and the working environment has become more use-friendly, which greatly improves personnel work efficiency. Not only that, but maintenance costs are also reduced because the company no longer has to run extensive wiring to add new light switches, which is costly and does not disrupt normal operations.
How Bluetooth Mesh Gateway Help
At the same time, the building management team can also use various data, uploaded by Bluetooth mesh gateway to the cloud server, to understand the status of the entire building and various services, and at the same time use these data to optimize the system to the best condition. Bluetooth mesh network and Bluetooth mesh gateway work together to allow you to easily and cost-effectively know the services of the entire building, and control automatic behaviors wirelessly.
Bluetooth Mesh Gateway Solutions Offered by Dusun IoT
The Bluetooth mesh gateway launched by Dusun IoT interconnects BLE devices in buildings (such as smart lights, central air conditioners, security alarm systems, etc.) and cloud-based (private or public) management servers. Bluetooth mesh gateway provides a centralized security platform for acquiring various data from external sonsors and centrally integrating them. At the same time, Dusun IoT’s Bluetooth mesh gateway also has the edge computing function, which can directly issue instructions after performing edge computing on the data, so as to improve the response time of smart lighting equipment. This intelligence enables real-time processing and communication responses without relying on servers.
Working Principle of Bluetooth Mesh Gateway
- Bluetooth sensors collect smart building data.
- The Bluetooth mesh gateway integrates all relevant data, analyzes it, and provides (internal and internal) communication.
- The Bluetooth mesh gateway uses its advanced communication technology to forward the data to the cloud-based management center.
Advantages of Dusun IoT Bluetooth Mesh Gateway
Our Bluetooth gateway, including Bluetooth mesh gateway, can interconnect and collect data from different BLE devices. It breaks down data silos in smart buildings by integrating data across regions and disparate platforms that are often incompatible. Dusun IoT’s Bluetooth mesh gateway allows all IoT devices to communicate with each other without the hindrances imposed by uniquely dependent system software.
Quick to Market
Dusun IoT Bluetooth mesh gateways adopt flexible modular design. Therefore, the productized gateways can be directly introduced to the market only by transplanting the application program.
Bluetooth mesh is the only network topology based on mandatory security keys, which can protect the network at multiple levels of the protocol stack. Every data packet must be encrypted and authenticated.
Powerful Edge Computing Capability to Maximize Cost Savings
The Bluetooth mesh gateway solution with edge intelligence capabilities can directly process data for perception, integration, reasoning, judgment and decision-making. This also facilitates more and faster decision-making systems such as HVAC utilization, power, electrical management, water usage, etc.
Dusun IoT Bluetooth mesh gateway brings a full range of communication channels between IoT sensors and smart analytics (whether running on-device, locally or remotely). Our Bluetooth mesh gateway supports communication between wireless and wired devices. It forwards various data acquired from the sensors to the analysis engine (cloud server) and sends the necessary instructions back to the sensors. If you are looking for a reliable building automation solution, please feel free to leave your requirements, we will prepare a complete set of detailed IoT solutions for you.
