How to connect mobile phone hotspots with Bluetooth

Generally speaking, Bluetooth should not be able to connect to mobile phone hotspots. Generally, this mobile phone can be used directly, but it is useless. Usually yours still doesn't work. The following is the extended information about Bluetooth.

Bluetooth technology is an open global specification for wireless data and voice communication. It is a special short-distance wireless technology connection based on low-cost short-distance wireless connection, which establishes a communication environment for fixed and mobile devices. [ 1]

Bluetooth enables some portable mobile devices and computer devices to connect to the Internet without cables, and can access the Internet wirelessly.

abstract

Bluetooth is a radio technology, which supports short-distance communication of devices (generally within 10m). It can exchange wireless information between many devices, including mobile phones, PDA, wireless headsets, notebook computers and related peripheral devices. Using Bluetooth technology can effectively simplify the communication between mobile communication terminal devices, and also successfully simplify the communication between devices and the Internet, which makes data transmission faster and more efficient and broadens the road for wireless communication. [2]

As a small-scale wireless connection technology, Bluetooth can realize convenient, fast, flexible, safe, low-cost and low-power data communication and voice communication between devices, and it is one of the mainstream technologies to realize wireless personal area network communication. Connecting with other networks can bring more extensive applications. It is a cutting-edge open wireless communication, which enables all kinds of digital devices to communicate wirelessly. It is a wireless network transmission technology, originally used to replace infrared rays. [3]

Bluetooth technology is an open global wireless data and voice communication standard. Based on low-cost short-distance wireless connection, it establishes a special connection for the communication environment of fixed and mobile devices. Its essence is to establish a universal radio air interface for the communication environment between fixed devices or mobile devices, and further combine communication technology with computer technology, so that various 3C devices can communicate or operate with each other in a short distance without wires or cables. Simply put, Bluetooth technology is a technology that uses low-power radio to transmit data between various 3C devices. Bluetooth works in the global 2.4GHz ISM (that is, industrial, scientific and medical) frequency band, using the IEEE802. 15 protocol. As a new short-range wireless communication technology, it is strongly promoting the development of low-rate wireless personal area network. [2]

trait

The characteristics of Bluetooth technology and Bluetooth products mainly include:

1, Bluetooth technology is suitable for many devices. Computers and telecommunications can communicate with each other through wireless networking without cables. [5]

2. The working frequency band of Bluetooth technology is universal all over the world, which is suitable for users all over the world to use without borders, and solves the "national border" obstacle of cellular phones. Bluetooth technology products are very useful. With a Bluetooth device, you can search for another Bluetooth technology product and quickly establish a connection between the two devices. With the help of control software, data can be transmitted automatically. [5]

3. Bluetooth technology has strong security and anti-interference ability. Because Bluetooth technology has frequency hopping function, ISM frequency band is effectively prevented from encountering interference sources. Bluetooth technology has good compatibility. Bluetooth technology has been able to develop into a technology independent of the operating system, achieving good compatibility in various operating systems. [5]

4. Short transmission distance: At present, the main working range of Bluetooth technology is about 10 meter. After increasing RF power, Bluetooth technology can work in the range of 100 meters. Only in this way can we ensure the working quality and efficiency of Bluetooth and improve the propagation speed of Bluetooth. In addition, the interference between Bluetooth technology and other electronic products can be effectively reduced during the connection process, thus ensuring the normal operation of Bluetooth technology. Bluetooth technology not only has high communication quality and efficiency, but also has the characteristics of high communication security.
