The latest market analysis shows that Bluetooth is becoming an important driving
As early as a few years ago, major market research institutes made optimistic predictions about the potential of the Internet of Things. In the future, the number of Internet of Things connections will reach tens of billions, far exceeding the number of mobile phone connections. In fact, from the current results of the development of the Internet of Things, this vision is gradually being realized. Of course, the number of Internet of Things connections varies, and Bluetooth will play an important role in it.

The Evolution Direction of Bluetooth Technology is More Internet of Things

Bluetooth has been used for decades as an "old" technology, its application scope and market recognition are increasing, which is inseparable from its long-term evolution of technology. Especially in recent important evolutionary versions, Bluetooth technology has become more "IoT-like", such as:

BLE solves the problem of excessive power consumption of Bluetooth, which 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, but also have a positive significance in reducing costs. The emergence of BLE has enabled a variety of smart home and wearable devices to start using Bluetooth technology for transmission.

Mesh solves the problem of network coverage, because in regional scenarios, the cost of selecting an independent AP or gateway for network coverage is very high, while using Mesh technology can solve the networking problem of multiple devices in a regional application scenario at a very low cost.

High-precision positioning opens up a larger application market. Location data, as a basic data dimension, will have broad application prospects in the future. More than two-thirds of IoT devices will collect location data in the future. In positioning, accuracy is the core indicator. In the latest version 5.1 of Bluetooth, AOA positioning technology has been added. Compared with traditional RSSI positioning, the accuracy has been improved from meter level to centimeter level.

Bluetooth Corps is expanding

The continuous development of Bluetooth technology is closely related to the promotion of Bluetooth Technology Alliance (SIG). SIG plays an important role in the formulation of Bluetooth standards, the evolution of technical versions, the construction of communities and the promotion of market brands. On May 23, 2019, Bluetooth Asia 2019 was held in Shenzhen. At the conference, the latest development of Bluetooth was demonstrated, especially the growing strength of the current Bluetooth Corps.

It can be seen that in 2018, the membership of Bluetooth Technological Alliance is close to 35,000 enterprises. At present, with the increasing number of wireless communication technologies on the market, Bluetooth still maintains its strong vitality. In the Asia-Pacific region, which we are most concerned about, Bluetooth Technological Alliance has more than 12,000 enterprises, among which China has more than 6,000 enterprises, accounting for half of the left of the Asia-Pacific region. Right.

Bluetooth shipments have also been steadily rising, with 3.7 billion in 2018 and 5.4 billion in 2023.

Among them, the number of low-power Bluetooth devices will be increasing. It is expected that in 2023, 90% of Bluetooth devices will use low-power Bluetooth. Of course, classical Bluetooth (BR/EDR) will not exit the market. It is more likely to be used in combination with low-power Bluetooth dual-mode. It is expected that in 2019, 2.7 billion Bluetooth devices will be equipped with both BR/EDR and low-power Bluetooth when they leave the factory.

Location service will become the fastest growing application function of Bluetooth

Functionally speaking, audio transmission, data transmission, location service and device network are the four most important application functions of Bluetooth. The following is the Bluetooth Technology Alliance's forecast of shipments in these application areas.

Audio transmission

Bluetooth frees headphones, speakers and home entertainment devices from wires, bringing radical changes to wireless audio transmission.

data transmission

Every year, millions of new low-power Bluetooth data transmission devices from fitness trackers and health monitors to toys and tools enable consumers to get rid of wires.

Location services

New developments in Bluetooth technology help to achieve powerful, low-cost indoor positioning and location service solutions.

Equipment network

The introduction of Bluetooth mesh network paves the way for the realization of large-scale equipment network, thus monitoring and automating the management of thousands of interconnected devices.

It can be seen that audio transmission and data transmission are the most important functions of Bluetooth technology, and the corresponding shipments are also growing steadily. The biggest bright spot is positioning application. Although the current overall volume is not large, the composite growth rate of Bluetooth positioning function will reach 43% in the next five years. The composite growth rate of Mesh device networking is 23%.
