As an "old" technology that has been used for decades, Bluetooth's application range and market acceptance are increasing, which is inseparable from its long-term evolution of evolving technology. Especially in recent important evolutions, Bluetooth technology is more IoT,For example：
BLE solves the problem of excessive Bluetooth power consumption. The power consumption is a very core indicator in IoT devices, because low power consumption can not only increase the user's product experience, especially for battery-powered devices. There is also a positive significance in reducing costs. The emergence of BLE has enabled a variety of smart homes and wearable devices to begin to transmit using Bluetooth technology.
Mesh solves the problem of network coverage, because in a regional scenario, the cost of selecting a separate AP or gateway for network coverage is high, and Mesh technology can solve multiple devices in a certain application scenario at a low cost. Networking problem.
High-precision positioning opens up a larger application market. As a basic data dimension, location data has broad application prospects in the future. More than two-thirds of IoT devices will collect location data in the future, and in terms of positioning, accuracy is One of the most core indicators. In the latest version 5.1 of Bluetooth, the AOA positioning technology has been added, and the accuracy has been increased from the meter level to the centimeter level compared to the conventional RSSI positioning.
The power of the Bluetooth Legion is gradually expanding
The reason why Bluetooth technology can continue to develop, and the promotion of the Bluetooth Technology Alliance (SIG) is also inseparable. The SIG has greatly promoted the development of Bluetooth standards and the evolution of technology versions, community construction and market brand promotion. . On May 23, 2019, Bluetooth Asia 2019 was held in Shenzhen. At the conference, the latest developments of Bluetooth were demonstrated, especially the current strength of the Bluetooth Legion.
It can be seen that in 2018, the members of the Bluetooth Technology Alliance are close to 35,000 companies. At present, with the increasing number of wireless communication technologies on the market, Bluetooth still maintains its strong vitality. In the Asia-Pacific region, there are more than 12,000 Bluetooth technology alliance companies, of which more than 6,000 are in China, accounting for about half of the Asia-Pacific region.
Shipments of Bluetooth devices have also steadily increased. In 2018, shipments of Bluetooth devices were 3.7 billion units, and this number is expected to reach 5.4 billion units by 2023.
The number of low-power Bluetooth devices will increase day by day. It is expected that in 2023, 90% of Bluetooth devices will adopt low-power Bluetooth. Of course, Classic Bluetooth (BR/EDR) will not exit the market, and more Used in conjunction with the low-power Bluetooth dual-mode, it is expected that in 2019, 2.7 billion Bluetooth devices will be equipped with BR/EDR and low-power Bluetooth at the factory.
Location services will be the fastest growing application function Bluetooth
Functionally speaking, audio transmission, data transmission, location service, and device network are the four most important application functions of Bluetooth. Below is the Bluetooth Technology Alliance's forecast for shipments for these applications.
