Bluetooth technology is developing rapidly
In the past two years, the rapid growth of the wearable device market is inseparable from the development of Bluetooth technology. With the rise of Bluetooth 4.x, the rise of mobile Internet, Bluetooth technology applications from mobile phones, tablets and other portable devices like the Internet of Things, medical and other fields, many mobile platform-based Bluetooth applications bring new opportunities for the entire wireless market.
In 2018, the Bluetooth Special Interest Group (SIG) celebrated its 20th anniversary. In 1998, the Bluetooth Technology Alliance, consisting of only a few member companies, was involved in finding alternatives for voice and data transmission cables for mobile phones. Today, the Bluetooth Technology Alliance works with 34,000 member companies to develop and innovate flexible, stable, and secure wireless connectivity solutions.
From prototyping to becoming the global wireless connectivity standard, Bluetooth is gradually becoming available in industries such as wireless audio, wearables, and building automation. Bluetooth is changing the world.
development trends of Bluetooth technology
The application of Bluetooth technology is considered to be very broad and has great potential. It can be applied to wireless devices (such as PDAs, mobile phones, smart phones, cordless phones, image processing devices (cameras, printers, scanners), security products (smart cards, identification, ticket management, security checks), consumer entertainment (headphones, MP3, games) automotive products (GPS, ABS, power systems, airbags), household appliances (television, refrigerators, electric ovens, microwave ovens, audio, video recorders), medical fitness, construction, toys and other fields.
Bluetooth technology in the smart home market
It is reported that due to the promotion of mesh technology, the annual compound growth rate of Bluetooth technology in smart homes from 2013-2018 is as high as 232%. The mesh technology changes the traditional Bluetooth networking mode, and forms a grid in the form of broadcasts, which makes up for the shortcomings that traditional Bluetooth cannot form a large-scale network, and enhances the ability to penetrate the wall, effectively expanding the application prospect of Bluetooth.
Robin Heydon of the CSR Institute for Global Standards pointed out in his speech that 87 Bluetooth devices, such as doors and windows, garages, kitchen alarms, dishwashing tables, floor drains, dining tables, tables and chairs, bedrooms, balconies, etc., may be used only in home content. .
On the other hand, the emerging low-power Bluetooth technology (BLE) also plays a pivotal role in the entire low-power wireless communication market, and the outbreak of the smart home market will greatly promote the rapid growth of BLE technology. There are three main reasons: First, BLE itself has a low power consumption advantage, and after several years of development, Bluetooth technology has become a generally accepted standard in the market; followed by mobile operating system support for Bluetooth, currently Bluetooth technology is already a portable device Standard; finally, the development of related applications and accessories, among which Bluetooth headset, Bluetooth car and Bluetooth MP3 are very popular among users. Zhuo Wentai said that the future Bluetooth technology alliance will target all scenarios that require low power consumption and low speed. He pointed out that Bluetooth will complement the WiFi in the future.
Bluetooth chip with processing capability combined with sensor
In order to achieve better intelligence, the Bluetooth chip will be deeply integrated with the sensor in the future. The most likely is that the manufacturer will provide a Bluetooth chipset in the form of a SIP package. Zhuo Wentai said that in the future, the combination of Bluetooth and sensors can send the collected data directly to the cloud for processing, so that each device equipped with a Bluetooth module becomes a smart device, and such an application can have great potential in homes and offices. .
indoor positioning based on Beacon technology
Wentai Zhuo said that the Bluetooth-based Beacon positioning technology has high precision and low cost, which will subvert the future retail model. For example, when you walk into a retail store, Beacons positioning technology can pinpoint your positioning. When you walk to the jacket window, the phone will pop up relevant promotional information, and even recommend clothes based on your previous purchase big data.
