The conceptual meaning of the Internet of Things is that objects and people or animals, animals and things are defined as the only kind of identity that transmits data over the network without human interaction or human interaction. It is reported that by 2018, there will be 40 billion "things" connected to each other through the Internet of Things. The Internet of Things is driven by sensors and Internet connections, and all “things†connected to the network must be equipped with sensors or actuators. The sensors use a communication mode that can be detected by the main control device (such as mobile phones, tablets, etc.). And communicate with the master device to communicate.
The Internet of Things low-power Bluetooth is known as "Bluetooth Smart", a wireless communication technology designed and launched by the Bluetooth Technology Alliance. Low-power Bluetooth has several requirements: First, low-power Bluetooth is installed with button battery, and now IoT low-power Bluetooth devices need to use standard button batteries for many years, low-power Bluetooth Therefore, it is very energy-saving and energy-saving. It depends on an ultra-low peak standard. In idle mode, it basically does not need to consume power. Second, the low-power Bluetooth communication distance is up to 100 meters, but this specification distance does not clearly limit the communication distance on the SIG website, so Bluetooth solution manufacturers can produce low-power Bluetooth with communication distance greater than 100 meters. Communication equipment. Third, the rate of data transmission is as high as 1 Mbps, which is a very good result so far. Fourth, the widespread adoption of mobile smart device manufacturers, low-power Bluetooth has been supported by mainstream systems such as IOS system and Android system. It is expected that in 2020, 95% of smartphones will support low-power Bluetooth, a huge ecosystem. The system has created the popularity of low-power Bluetooth.
Low-power Bluetooth has been popularized in many industries. Smart wearables and smart home devices have fully used low-power Bluetooth communication protocols. Many Bluetooth solution manufacturers have invested heavily in the research and development of smart home and smart wearable device solutions. Manufacturers of low-power Bluetooth solutions, especially in smart wearables and smart home devices. Its latest development is a solution for smart wearable device integration. What is the "integrated" smart wearable device solution is to use smart wearable Bluetooth bracelet to connect and manage a whole set of smart devices in life. The integrated solution developed by Shengrun Technology has mobile payment, many-to-many connection, smart door lock, LED light management, intelligent weight scale and other functions, can support multiple people to connect management at the same time, directly accelerate the coverage of the Internet of Things low-power Bluetooth industry.
Low-power Bluetooth communication technology is currently the most widely used wireless communication technology in the Internet of Things industry. Currently, the biggest competitor of low-power Bluetooth in wireless communication protocols is the wide-ranging proprietary protocols of Wi-Fi, ZigBee and Ant+ series. All four communication technologies need to access the network. It is undoubtedly the best choice to analyze WIFI from the Internet of Things devices. However, the power consumption of WIFI is relatively large, so we need to use the button battery device to connect to the LAN through WIFI. So, WIFI is only used for some specific scene applications. Therefore, the ideal network for most electromagnetically powered IoT devices that need to communicate with a master device is PAN, which is the advantage of the Bluetooth low energy communication standard over the other three communication methods.
In the Internet of Things industry, low-power Bluetooth is the best choice for wireless communication applications. Its advantages are low cost, low power consumption, fast transmission rate and wide penetration of mobile smart devices. Therefore, more and more smart homes Smart wearable devices and medical monitoring devices consider low-power Bluetooth communication protocols to be the first choice. In the national IoT development planning policy, the major measures of smart city construction will vigorously apply the low-power Bluetooth communication protocol, so the development prospect of low-power Bluetooth will be incalculable.
