What are the characteristics of Bluetooth communication? What are the characteristics of Bluetooth t

Bluetooth technology is a short-range wireless communication technology, the use of "Bluetooth" technology, can effectively simplify the communication between mobile communication terminal devices such as handheld computers, laptops and mobile phones, and can also successfully simplify the communication between these devices and the Internet, so that the data transmission between these modern communication equipment and the Internet becomes more rapid and efficient, and broadens the road for wireless communication. To put it in layman's terms, Bluetooth technology makes some modern easy-to-carry mobile communication equipment and computer equipment to be networked without the help of cables, and can realize wireless Internet, and its practical application range can also be extended to various household appliances, consumer electronics and automobiles and other information appliances, forming a huge wireless communication network.

Bluetooth. An open global specification for wireless data and voice communications. Bluetooth technology is the technology used to establish a common short-range wireless interface in the communication environment between fixed or mobile devices.

Its transmission frequency band is a universal frequency band. It provides a transmission rate of 1Mbps and a transmission distance of 10m. Cons:

The chip size and ** are difficult to decrease, the anti-interference is not strong, the transmission distance is too short, and the information security problem is too long.

Bluetooth, transmission distance 2-30m, rate 1mbps, power consumption between zigbee and wifi.

Bluetooth is a low-cost, high-capacity, short-range wireless communication specification. A Bluetooth laptop is a laptop with Bluetooth wireless communication function. The name Bluetooth has a legendary story.

In the 10th century, the Norse princes competed for hegemony, and the King of Denmark stepped forward, and with his tireless efforts, the bloody war was stopped, and all parties sat down at the negotiating table. Through communication, the princes released their suspicions and became friends. Because the Danish king loves to eat blue plums, so that his teeth are dyed blue, he is known as the king of Bluetooth, so Bluetooth has become synonymous with communication.

Now, a thousand years later, when a new wireless communication specification was introduced, people used Bluetooth to name it.

In 1995, Ericsson was the first to propose the concept of Bluetooth. The Bluetooth specification operates in the microwave frequency band, with a transmission rate of 1m bytes per second, a maximum transmission distance of 10 meters, and can reach 100 meters by increasing the transmission power. Bluetooth technology is open to the world, with good compatibility on the global scale, and the whole world can be connected by low-cost invisible Bluetooth networks.

Bluetooth technology is not only used in computers, but also in many electronic devices such as mobile phones, digital cameras, video cameras, printers, fax machines, home appliances and so on, which can be used to achieve wireless communication without having to drag a tail (connecting cable). With the popularization of Bluetooth technology, home decoration is no longer troubled by the wiring of electrical appliances; When using home appliances, you don't have to worry about a lot of remote controls, a mobile phone or a car key can do everything; When you are away from home, the company's work arrangement and the picture of your relatives at home can be obtained anytime and anywhere; There is no need to queue up for punching in and paying fees, and you can easily complete the ...... without entering the door by passing near the payment pointThe widespread use of Bluetooth technology will make our lives incredibly easier.

Bluetooth is a wireless communication standard that is suitable for short ranges. At present, the latest version of the stuffy shirt is the Bluetooth standard, which was proposed by the Bluetooth Special Interest Group in 2016.

The advantages of Bluetooth are: low power consumption, low latency, high security, and the ability to connect regardless of obstacles within the effective range.

The disadvantages of Bluetooth are: the transmission distance is short, and the transmission speed is not high.

Although Bluetooth technology has been screaming for several years, there is no major application and promotion, but with MSI and other motherboard leaders have launched Bluetooth series products one after another, people in the industry who have always been conservative have begun to think that Bluetooth has hope to enter ordinary people's homes this year. But, ironically, when Bluetooth seems to be ushering in a spring in the hardware market, his "younger brother" - Bluetooth has already set the standard specification.

The outline of the standard specifications for Bluetooth is as follows:

Supports transmission rates of 4m, 8m and 12m per second.

Distributed media-access control protocols are available

When operating at a distance of 10 meters, peak power is expected to be twice that of Bluetooth.

The organization that developed Bluetooth also offers a protocol with a transmission rate of 2 to 3 Mbits-second, called Bluetooth.

Bluetooth is expected to be released in 2004.

Bluetooth is not meant to be a complete replacement for Bluetooth.

Bluetooth chips will account for 20% of the total Bluetooth chip market

For the time being, we can only know these details about the specification of Bluetooth, because Bluetooth has disappointed many people, so whether Bluetooth is on paper or "turning over and being a man", we have to wait and see.

The so-called Bluetooth (Bluetooth) technology, in fact, is a short-distance wireless communication technology, the use of "Bluetooth" technology, can effectively simplify the communication between mobile communication terminal devices such as handheld computers, laptops and mobile phones, and can also successfully simplify the communication between these devices and the Internet, so that the data transmission between these modern communication equipment and the Internet becomes more rapid and efficient, and broadens the road for wireless communication. To put it in layman's terms, Bluetooth technology makes some modern easy-to-carry mobile communication equipment and computer equipment to be networked without the help of cables, and can realize wireless Internet, and its practical application range can also be extended to various household appliances, consumer electronics and automobiles and other information appliances, forming a huge wireless communication network.

The background of the formation of "Bluetooth" is as follows: in May 1998, Ericsson, Nokia, Toshiba, IBM and Intel Corporation, five well-known manufacturers, jointly carried out the standardization of short-range wireless communication technology proposed Bluetooth technology, the purpose of which is to provide a short-range, low-cost wireless transmission application technology. The five vendors have also formed a Bluetooth Special Interest Group to enable Bluetooth technology to become the wireless communication standard of the future.

Chip overlord Intel is responsible for the development of semiconductor chips and transmission software, Ericsson is responsible for the development of wireless RF and mobile** software, and IBM and Toshiba are responsible for the development of notebook interface specifications. In the second half of 1999, the famous industry giants Microsoft, Motorola, Sankang, Lucent and five companies of the Bluetooth special group jointly initiated the establishment of the Bluetooth technology promotion organization, thus setting off a "Bluetooth" boom around the world. The global industry is about to develop a large number of Bluetooth technology application products, so that Bluetooth technology presents an extremely broad market prospect, and indicates that the beginning of the 21st century will usher in a magnificent wave of global wireless communication.

Bluetooth and infrared are both a kind of wireless transmission, infrared has been used for a long time, and Bluetooth is a wireless transmission method that has developed rapidly in recent years.

Compared with infrared, Bluetooth has several advantages: 1. The transmission speed is about 10 times that of infrared 2. The effective distance is long, generally 10 meters 3. Stable 4. Do not transmit in a straight line.

Wireless transmission, no traffic, no wifi, close distance transmission of data, connection of data, transmission of instructions, etc.
