①More than 1,300 years ago, a brave people appeared in Northern Europe, the Vikings. The Vikings were adventurous and well-traveled. They sailed their ships with a sword in one hand and a torch in the other, and their stories spread throughout Europe. Their greatest leader was their king, Harald "Bluetooth". In Denmark, in Scandinavia and throughout Europe, "Bluetooth" stood for "unity, expansion, tolerance, courage," and "conquest".
②When history steps into the door of the 21st century, a kind of wireless communication technology proposed by the descendants of the Vikings, the Swedes, "to make complex cables disappear into the air" is known as "Bluetooth" technology (Bluetooth). At its core is the harmonization and inclusion of global standards.
③This globally harmonized standard brings endless creativity. It is in the last 10 meters of the modern communication network, will be like a kind of ubiquitous digital nerve endings, a variety of network terminal equipment, a variety of information technology equipment, are "wireless" to connect.
④Bluetooth technology is used to replace the portable or fixed electronic devices used on the cable or wire short-range wireless connection technology. The use of Bluetooth technology, can effectively connect cell phones and laptops, PDAs, and a variety of digital information devices, so as to get rid of the commonly used wired cables; at the same time, the formation of a kind of personal side of the network, so that a variety of information technology around the mobile portable devices can be seamlessly realize the resources **** enjoy.
⑤Because of its openness, Bluetooth technology is currently only a specification and has not yet become an industry standard. There are still some problems with interoperability between devices of different brands and models. However, Bluetooth technology itself has many advantages: Bluetooth generally works in the ISM band of 2.4GHz, which is a globally used industrial, scientific and medical band, and the use of this band does not need to apply for a license to the radio resource management department of each country; it can be used to transmit data and voice in real time; due to the use of advanced FM and error correction coding technology, Bluetooth has a very good anti-jamming ability, and devices equipped with Bluetooth can communicate more reliably with each other. Bluetooth has good anti-jamming ability, and the devices equipped with Bluetooth can communicate with each other more reliably. In addition, Bluetooth has strong portability and can be applied to a variety of communication occasions, such as WAP, GSM, etc., and roaming can be flexibly realized after the introduction of identification, and security is also good. Moreover, Bluetooth devices have low power consumption, easy to realize, easy to promote, and less harmful to human body.
6For the current development, Bluetooth technology has been used in devices such as cell phones, headphones, PADs, digital cameras and digital camcorders. Due to the high popularity of cell phones, Bluetooth cell phones have become the main application of Bluetooth technology at present.
⑦A Bluetooth-enabled cell phone with a small Bluetooth headset allows you to place the phone in your pocket for hands-free calling. In this way, in the bitter cold wind, while driving, in the hands of busy time, can be convenient to answer the phone, but also can avoid cell phone radiation.
⑧ Bluetooth cell phone can be easily connected to the computer to achieve the file transfer, in addition to pictures, ringtones, and Java games, general documents can be worn to the Bluetooth cell phone, so that you can use the Bluetooth cell phone as a U disk. Bluetooth cell phone can be in a certain range and laptop computer wireless connection, so that the laptop computer wireless Internet access has become a reality.
9Two users with the same Bluetooth cell phone can also exchange business cards, phone calls, and ringtones, or play games wirelessly. Together with the matching Bluetooth helmets, Bluetooth glasses, Bluetooth jackets and a series of other products, the wireless charm of Bluetooth allows you to experience a fashionable life.
⑩In fact, Bluetooth can also be used in wireless devices, image processing equipment, security products, consumer entertainment, automotive products, home appliances and many other areas. As Bluetooth technology continues to mature, a variety of Bluetooth products will penetrate into people's lives, change the way people live and work, and greatly improve people's quality of life.
