What is Bluetooth?　　

The so-called Bluetooth technology is actually a short-range radio technology. Using "Bluetooth" technology, it can effectively simplify the communication between mobile communication terminal devices such as handheld computers , notebook computers and mobile phones . Simplify the communication between the above devices and the Internet , so that the data transmission between these modern communication devices and the Internet becomes more rapid and efficient, and the road for wireless communication is widened. Bluetooth adopts a decentralized network structure and fast frequency hopping and short packet technology, supports point-to-point and point-to-multipoint communication, and works in the global 2.4GHz ISM (ie industrial , scientific , medical ) frequency band . Its data rate is 1Mbps. The time division duplex transmission scheme is used to realize full duplex transmission.

source of bluetooth name

The name Bluetooth comes from Harald Blatand, a Danish king 　　in the tenth century . Blatand in English can be interpreted as Bluetooth (Bluetooth) because the king likes to eat blue plums, and the gums are blue every day, so it is called Bluetooth.

The origin of Bluetooth The founder of Bluetooth is Ericsson of Sweden, which has been researching and developing as early as 1994. In 1997, Ericsson contacted other equipment manufacturers and sparked a strong interest in the technology. In February 1998, five multinational corporations, including Ericsson, Nokia, IBM, Toshiba and Intel, formed a Special Interest Group (SIG) with the common goal of establishing a global small-scale wireless communication technology, the current Bluetooth.

The name of Bluetooth comes from the 10th century Danish king Harald Blatand - the English translation is Harold Bluetooth (because he likes to eat blue plums very much, so his teeth are blue every day). In the preparatory stage of the industry association, a very expressive name is needed to name this high technology. Industry organizers, after a night of discussions about the history of Europe and the future of limitless technology, some thought it would be more fitting to be named after King Blatand. King Blatand united what is now Norway, Sweden and Denmark; he was articulate and sociable, like this forthcoming technology, which would be defined as allowing coordinated work between different industrial fields, maintaining the various systems Good communication between fields such as computing, work between mobile and the automotive industry. So the name was settled on.

About the Bluetooth SIG

The Bluetooth SIG (Bluetooth Special Interest Group Bluetooth Special Interest Group) is a trade association of leading manufacturers in the telecommunications, computer, automotive, industrial automation and networking industries. The group is committed to advancing the development of Bluetooth wireless technology, developing a low-cost wireless specification for connecting mobile devices over short distances, and bringing it to market.

Bluetooth SIG offices around the world include: Seattle, USA (World Headquarters); Kansas City, USA (US Headquarters); Malmö, Sweden (Europe, Middle East and Africa (EMEA) Headquarters); Hong Kong SAR, China (Asia Pacific Region) headquarters).

The entire staff of the Bluetooth SIG includes Dr. McFly, Executive Director, Anders Edlund, Director of Marketing, as well as sales, engineering and operations experts. In addition to support from the Bluetooth SIG (Bluetooth Special Interest Group), volunteers from member companies play an important role in running the Bluetooth SIG.

The sponsoring companies of the Bluetooth SIG are Agere, Ericsson, IBM, Intel, Microsoft, Motorola, Nokia and Toshiba. On October 13, 2006, the Bluetooth SIG (Bluetooth Technology Alliance) announced that Lenovo would replace IBM as a founding member of the organization, effective immediately. By becoming a founding member, Lenovo will join other industry leaders Agere Systems, Ericsson, Intel, Microsoft, Motorola, Nokia, and Toshiba with a seat on the Bluetooth SIG's board of directors and actively promote the development of the Bluetooth standard. develop. In addition to its founding members, the Bluetooth SIG includes more than 200 Alliance member companies and approximately 6,000 application member companies.

The advantages of bluetooth technology are available 　　worldwide

The Bluetooth wireless specification is freely available to our member companies worldwide. Manufacturers in many industries are actively implementing this technology in their products to reduce the use of cluttered wires for seamless connectivity, streaming stereo, data or voice communications. Bluetooth technology operates in the 2.4 GHz band, a license-free Industrial, Scientific, Medical (ISM) radio band. Because of this, there is no charge for using Bluetooth technology. However, you must register with your mobile phone provider to use GSM or CDMA, and you will not be charged anything for using Bluetooth technology other than the device fee.

Equipment range

Bluetooth technology has been used more widely than ever. Products that integrate this technology range from mobile phones to automobiles to medical devices, and users who use this technology range from consumers, industrial markets, to enterprises, and more. Low power consumption, small size and low-cost chip solutions make Bluetooth technology even in extremely small devices. Check out the wide range of products offered by our members in the Bluetooth Product Catalog and Component Product List.

easy to use

Bluetooth technology is an instant technology that requires no fixed infrastructure and is easy to install and set up. You don't need cables to connect. It's also easy for new users - all you need to do is own a Bluetooth branded product, check the available profiles, and connect it to another Bluetooth device using the same profile. The subsequent PIN code process is as simple as you would at an ATM machine. You can take your personal area network (PAN) with you when you're out and about, and even connect to other networks.

Global Specifications

Bluetooth wireless technology is the most widely supported, feature-rich and secure wireless standard on the market today. A worldwide qualification process tests members' products for compliance with standards. Since the release of the Bluetooth specification in 1999, more than 4000 companies have become members of the Bluetooth Special Interest Group (SIG). At the same time, the number of Bluetooth products on the market has grown exponentially. The number of products has doubled for four consecutive years, and the number of installed base stations may reach 500 million by the end of 2005.
