What do we mean by Bluetooth for mobile phones?

1. Bluetooth is BlueTooth. BlueTooth technology was co-founded by the Special Interest Group SIG (Special Interest Group) composed of Ericsson, Intel, IBM, Nokia, Toshiba and other companies. It is an open standard for wireless data and voice transmission. It mainly solves short-distance wireless connections, usually in the range of 10 cm to 10 meters. If the power is increased or related external equipment is added, such as a dedicated amplifier (Optional Amplifier), etc. Achieve a distance of 100 meters.

2. The main applications include the following main aspects:

(1) Support Internet access. Laptops or mobile phones with built-in BlueTooth chips can not only use PSTN (Published Swithed Telephone Network), ISDN (Integrated Services Digital Network), LAN (Local Area Net), including asymmetric digital Digital subscriber lines such as ADSL (Asymmetrical Digital Subscriber Loop) and xDSL are used for Internet connection, and cellular mobile networks can be used for Internet connection.

(2) Flexible switching of connection methods. Within the effective transmission range of the parent machine, such as at home, a mobile phone with a built-in BlueTooth chip can be used as a cordless phone. This is very important to Chinese users, because when used as a cordless phone, it can avoid two-way charges and save mobile phone costs. When the user leaves the effective range of the base unit's transmission, the mobile phone used as a cordless phone will automatically switch to the wireless network base station.

(3) Wireless connection between mobile phone and computer. At present, most connections between mobile phones and computers are achieved through IrDA infrared or RS232 serial lines. Now BlueTooth technology can replace these connection methods. BlueTooth technology is not only easy to apply but also has high data transmission speed. It can also simplify the mobile phone connector and may even eliminate the connector in the future.

(4) Wireless hands-free. Mobile phones connected using BlueTooth technology can achieve wireless hands-free work, which is very useful in certain fields, such as car-mounted mobile phones, multi-person video conferencing, etc.

(5) Synchronous data transmission. Whether in the office or at home, users can use BlueTooth and its corresponding programs to achieve synchronous transmission of information on computers, laptops, mobile phones, PDAs, etc. The information transmitted here can be not only text, but also pictures and images. Using a digital camera with BlueTooth function, after the user completes shooting, the image can be transferred to the mobile phone and then transferred to any other destination.

(6) Achieve large-scale data sharing, making users’ work easier. Using BlueTooth technology, mobile phones, computers, PDAs, printers, digital cameras, MP3 players, etc. can realize the mutual transmission of voice, text, images, files and other information, realize large-scale data sharing, greatly simplify office facilities, Makes users' work simpler and easier.
